Oil and gas in the energy mix. Canadian Production. This method entails grouping data to reflect what is homogeneous and multiple groups can be created to further simplify specific properties. OPEC and non-OPEC partners continue to throttle their oil supply affording market price stability. Initially, a shallower structure in this formation, Jonathan Field, was discovered and developed as a commercially productive oil reservoir, Later a deeper closure, Macintosh Field, was drilled with oil discovered there also. Analogues can be used to estimate likely reservoir parameters, initial rates or production profiles, as well as expected recovery factor and ultimate recovery. The oil & gas industry is no stranger to big data, in fact the industry has arguably been working with big data longer than anyone else. In our oil and gas report, we have translated the energy requirements of key demand sectors into the trends we expect to see across the value chain. Forecasting future oil and gas production for a well is one of the most important tasks of a reservoir engineer. It also becomes imperative to evaluate how different the aggregated parameters from the analogs are to the target reservoir. Sidle, R. E., & Lee, W. J. Canada.After a wild ride for producers over the last several years, the Canadian E&P outlook is a bit better for 2020. Modified Arps curve with a 10% minimum terminal decline rate. The Arps coefficient Di is related to the effective decline rate by: The effective decline rate for the above example is 85.0 %/yr. Production forecasting. Oil and Gas Production Forecast: 2018-2027 . Similar to conventional wells, future oil and gas production for unconventional wells is often forecasted by fitting a curve through historical production volumes then extrapolating the curve to predict future production, a technique called decline curve analysis (DCA). More information. Al-Kaabi, W.J. Figure 1 –Cumulative Probabilities of Analogs vs EUR (Pending permission approval). 2010. Figure 1. These wells often experience linear flow for a large portion of their life. You must log in to edit PetroWiki. Arps noted in his experience the b value ranged between 0 and 1 with the majority between 0 and 0.4. value of 0 leads to the special case of exponential decline: Although Arps did not discuss b values greater than one, reservoir engineers soon discovered that such values were usually associated with transient flow data, violating Arps’ assumption that the well is in boundary dominated flow. We also house a number of presentations and third party reports. "Petroleum Resources Management System." This page was last edited on 31 May 2016, at 11:27. Cover: Shell’s Olympus tension leg platform (TLP) is part of the Mars B development (forefront), located in 3,100 feet of water (945 m), installed in 2013 and designed with a production capacity to exceed over 100,000 BOE per day. Google Scholar A.U. In 2020, there will be some more ‘black swans’ which are by definition unpredictable instances which affect the market already. This brief introduction to decline curve analysis introduced the classic Arps equation and the modern modified Arps method which is widely used to forecast future production from unconventional wells. Rob McBride, Jesse Mercer and Brendan Nealon, Enverus Energy. In addition, the report contains an assessment of Danish oil and gas reserves, production forecasts and a description on the impact of hydrocarbon production on the Danish economy. The ESM procedure generates forecasts by using exponential smoothing models. With the emergence of unconventional wells, especially long horizontal laterals, in the last twenty years, Arps b values greater than one are quite common. Reliable production from all your oil and gas resources. Other aggregates of properties such as mobility ratio [(Kw/μw)/(Ko/μo)] can be used to determine how successful other miscible flood process, such as waterflood, will potentially perform. The distribution shown in Fig 1 represents a fairly good number of analogs. A master database of the properties of interest must be validated and normalized (normal probability distribution) while potential outliers are identified and eliminated. Production forecasts. A production forecast is performed on the basis of principle of material balance. Gas producers share many of the basic challenges of oil producers. Arps hyperbolic plots typically show a steep initial decline followed by an extended period of gentle decline. Society of Petroleum Engineers. "This paper introduces methodologies to forecast oil and gas production by exploring implementations of the AUTOREG, ESM, and MODEL procedures in SAS/ETS ®. He is editor and chapter author of SPEE Monograph 4, “Estimating Ultimate Recovery of Developed Wells in Low-Permeability Reservoirs”. Global oil production has absorbed the lion’s share of the impact, but natural gas output, which was previously set to grow, is also set to decline by 2.6 percent this year, Rystad Energy forecasts. FORECAST Crude Oil Forecast. Gas producers share many of the basic challenges of oil producers. Suncor Energy on Monday forecast higher production and spending for 2021 as the Canadian oil and gas producer expects consumer demand and commodity prices to recover from pandemic lows. Prices plummeted in the second quarter, with one day in April even closing at $9/b for Brent prices internationally and -$37/b for … At late times, the calculated decline rate can fall to a value of 1%/yr or less. Additionally, the DEA prepares an oil and gas consumption forecast, a so-called baseline scenario. Investment will be needed to add new oil and gas production capacity, and to operate existing assets safely and sustainably over this period, to deliver output levels that can meet predicted demand. Oil production was described by a simple equation with three empirical coefficients. Society of Petroleum Engineers. Oil And Gas Production Forecast: 2020 And Beyond. EIA forecasts U.S. dry natural gas production will average 90.9 Bcf/d in 2020, which is down from an average of 93.1 Bcf/d in 2019. Unique to each well, the three Arps coefficients, qi, Di, and b, are determined by the curve fit exercise. The downturn caused by COVID-19, however, is unlike any other. Long, D. R., and Davis, M. J., 1987, “A New Approach to the Hyperbolic Curve”, SPE 16237. Global facts and figures of EV … His current duties include unconventional reservoir engineering, reserve studies and economic evaluations, unconventional well performance analysis, and serving as an expert witness for litigation and regulatory hearings. Society of Petroleum Engineers. The extreme data demands of exploration geophysics alone has been a major reason for many advances in computing power, and even today some of the biggest supercomputers spend large amounts of time calculating seismic volumes. 2020 Forecast - U.S. oil and gas production /// U.S. crude output surges, overproduction wallops gas prices Log in to view this article. The companies that operate oil and gas pipelines and process the offshore output also shut ahead of the storm. 1. Feasibility of oil production predicting results influences the annual planning and long-term field development plan of oil field, so the selection of predicting models plays a core role.   All expected comparisons and analysis of analogs must satisfy PRMS’s definition of analogs as well as reserves where and when applicable. If there is a significant difference between analogs and target reservoir, a better understanding of the contributing parameter(s) will be necessary. The analog method is a more qualitative than quantitative approach which generally results in a wide range of estimates of performance with no clear basis for a most-likely estimate. CAPP releases its Crude Oil Forecast, Markets and Transportation report annually in late spring. Growth slows in 2020, hinging on global demand and the market's ability to support continually increasing output. Oil prices started strong this year at $64/b in January. Total pentanes plus and condensate will keep growing for the forecasted period from 418 Mbpd in 2019 to 604 Mbpd in 2039 underpinned by demand from oil sands and driven by liquids-rich natural gas drilling. Principal component analysis is a method that is used to recognize patterns in data to highlight similarities and differences is data sets. These production forecasts are used for estimating remaining reserves, optimizing production operations and business planning, among other tasks. The outlier was a high productivity well that had recovered many times the EUR when compared with wells closer to the target reservoir. At late times, the calculated decline rate can fall to a value of 1%/yr or less. as reflected by well spacing, lift mechanism, fluid injection type) can also be important in establishing the relevance of the analogy and becomes especially important when using analogues for prediction how a production profile will look, as opposed to just overall recovery factor. Using production data from an oil producing horizontal well initially above the bubble point, I will demonstrate a simple methodology to forecast gas-oil ratio using straight lines. Similar to conventional wells, future oil and gas production for unconventional wells is often forecasted by fitting a curve through historical production volumes then extrapolating the curve to predict future production, a technique called … The AI in Oil and Gas Ecosystem size was valued at $413 Million in 2018 and is expected to grow at ~16.2% CAGR from 2019 to 2020. One of the methods often used in this type of scenario is analog studies. Outside the U.S., North American drilling is slated to decline 7.1% during 2020, with Canada down and Mexico up. Sharma, A., Srinivasan, S., & Lake, L. W. 2010. Resources and reserves . Forecasts of how much oil and gas could be produced by the UK offshore industry have been revised upwards. http://dx.doi.org/10.2118/166449-MS. Society of Petroleum Engineers (U.S.). Organization of Petroleum Exporting Countries (OPEC) has increased its forecast for average daily oil production in Azerbaijan for 2020-2021. Enhanced oil recovery (EOR) schemes require analogs that satisfy most conditions in addition to type of fluid injected, injected rates and injection pressures. For a long time Colin Campbell has published (also in an Atlas) oil and gas forecasts up to 2030, more recently updated up to 2050. Analogs are similar types of reservoirs to the targeted pool, which help to reduce exploitation risk as well as to suggest the type of reservoir development mechanism applicable and what future production performance might be expected. Analysis of aggregates, such as productivity, makes a more compelling evidence of analogy. Production costs are coming down too. The global energy transition ties together established markets with emerging power sources of the future. These wells often experience linear flow for a large portion of their life. Cluster analysis is a way of analyzing groups of data by using homogeneity of the data as the classification criteria. LeeUsing Artificial Neural Networks to Identify the Well Test Interpretation Model (Includes Associated Papers 28151 and 28165 ) (1993) 8(03) Google Scholar. Oil and natural gas from deep shale formations are transforming the United States economy and its energy outlook. Cumulative probabilities of parameters, such as initial rates and original gas in place can be plotted against EUR for different analogs on a log-log basis. The classic DCA method developed by Arps for conventional wells has been adapted for use with unconventional wells. An example of the use of analogs can be found in shallow natural gas systems where probabilistic distribution of analog parameters can be used to generate initial gas rates and EUR. are expected to perform better in forecasting oil production in waterflooded oil fields. He has more than thirty-five years of experience in unconventional gas and oil reservoir engineering in domestic and international plays. The study covers onshore and offshore conventional oil, including shale and tight oil activity, conventional natural gas, coalbed methane, tight and shale gas, and the associated natural gas liquids (pentanes plus and condensate only). 3. Other important tasks will include missing value analysis and data standardization. Oil and Gas i Solution Brief Improve Oilfield Production Forecasting With Predictive Analytics For the oil and gas industry, production forecasting is a highly complex task, and as such requires an advanced analytical engine to achieve robust forecasts. SPE disclaims any and all liability for your use of such content. To achieve a good process of evaluating analogs, a consistent procedure must be put in place. Arps, J. J, 1944, “Analysis of Decline Curves”, Trans. This GLOMACS training course demonstrates how the financial and commodity markets provide useful information for the generation of “expected prices,” or forecast prices, in the critical areas of oil, natural-gas and refined products. A consideration of individual analogs can lead to the wrong conclusions regarding suitability of analogs. His forecasts for oil plus NGPL is compared to mine and to Pierre-René Bauquis (PRB), along with past liquids production data. The resulting forecasted rates and recoveries were erroneously high. Further, I will show how to acquire other reservoir engineering parameters such as initial producing gas-oil ratio and cumulative production up to the bubble point used in determining drainage area of a well. However, sporadic reports of credible b values greater than one were discussed by Long and Davis, With the emergence of unconventional wells, especially long horizontal laterals, in the last twenty years, Arps b values greater than one are quite common. This type of analysis requires ranking of similar types of reservoirs based on a large database of geologic and reservoir properties. Hodgin, J. E., & Harrell, D. R. 2006. The modified Arps method retains the original method for early time data then later imposes an exponential decline a specified decline such as 5%/yr. 2011. A comparison of a target reservoir with its analogs must show that these estimates are similar even if individual properties are slightly different. Oil and gas development projects need production forecasts for planning purposes and to understand the economic viability of each project. In the case of analyzing multiple analogs where the results appear different; the more conservative results will be beneficial to the overall objective of identifying suitable analogs. The remaining oil and gas in the reservoir determine future inflow performance relationship (IPR) and, therefore, production rates of wells. Petroleum Reserves and Resources Definitions. The resulting forecasted rates and recoveries were erroneously high. A good example of analog use in oil reservoirs is found in Sidle et al (2010)[1], which considers “a regionally productive formation” which “has multiple closures against updip faults as it dips to the south. Analogous features and characteristics can include approximate depth, pressure, temperature, reservoir drive mechanism, original fluid content, oil gravity, reservoir size, gross thickness, pay thickness, net-to-gross ratio, lithology, level of heterogeneity, porosity and permeability. Martin Rodriguez, H., Escobar, E., Embid, S., Rodriguez, N., Hegazy, M., & Lake, L. W. 2013. A b value of 0 leads to the special case of exponential decline: And a b value of 1 gives the special case of harmonic decline: Although Arps did not discuss b values greater than one, reservoir engineers soon discovered that such values were usually associated with transient flow data, violating Arps’ assumption that the well is in boundary dominated flow. ... Production forecasting. OPEC Monthly Oil Market reported in its November issue, that the average daily oil production of oil and other hydrocarbons in Azerbaijan in 2020 will be at 0.73 million barrels, with an increase by 0.01 million barrels compared to October's forecast. The annual report for 2015 will be released in separate sections. Also, it is fair to note that there are different petroleum recovery mechanisms and they continue to evolve. This increase contributes to total U.S. crude oil production reaching 11.4 million b/d in December 2021. The report projects a constrained outlook for Canadian oil production from 2019 to 2035. The oil & gas industry is no stranger to big data, in fact the industry has arguably been working with big data longer than anyone else. When the decline rate of the hyperbolic curve fell to a specified limiting rate - for example, 6%/year - an exponential decline was used to forecast future production. Although production will increase by 1.27 million barrels per day (b/d) by 2035, that growth rate is about 6% less than CAPP’s 2018 forecast.. Total annual production is expected to increase by an average of 3% until 2021, then slow to an average growth rate of 1% annually. Resources and reserves The percentage of resources in a field expected to be recoverable over the life of the field is termed the ultimate recovery. Type curves drive oil & gas operator decision making – production forecasting, reserves estimation, and investment decisions. AIME (1945), vol 160, p. 228. With little regard for reservoir physics, reservoir engineers began predicting future well performance with simple curve fits to production data early in the twentieth century. Petrol. Table 2 shows a comparison of SPE and SEC analog criteria and guidelines put together by Hodgin et al (2006)[2]. Oil production from legacy wells in the Permian Basin, for example, was projected to drop by 236,697 barrels per day in December, according to the U.S. Energy Information Administration’s latest Drilling Productivity report. A comparison of each of these parameters shows that specific properties, such as porosity or permeability, are lower in Macintosh Field. Sign up below to receive Tip of the Month email updates!

Dr. Seidle is an instructor for industry classes, primarily unconventional reservoirs. Further, I will show how to acquire other reservoir engineering parameters such as initial producing gas-oil ratio and cumulative production up to the bubble point used in determining drainage area of a well. The EIA forecast that Brent crude oil prices will average $43/b in the fourth quarter of 2020 and $49/b in 2021. ... Probabilistic Decline Curves and Production Forecasting. In the short-term, several key issues will be monitored for their effect on regional and global production outputs. Jill Feblowitz IDC Vice President, Utilities and Oil and Gas • Data size and complexity. These early empirical methods were summarized and extended in a semi-empirical, semi-rigorous method based on assumptions about the well and the reservoir it is draining by Arps in 19441. These sets of guidelines will require technical judgment and must be used on a case by case basis. These production forecasts are used for estimating remaining reserves, optimizing production operations and business planning, among other tasks. Some specific statistical techniques available to use in ranking analogs include principal component analysis as well as cluster analysis. New Approach to Identify Analogue Reservoirs. An Update on the Use of Reservoir Analogs for the Estimation of Oil and Gas Reserves. Analogues are not necessarily situated in the same geographical location. a steep initial decline followed by an extended period of gentle decline. Over 70% of this growth occurs in the United States to service new LNG export facilities. AndersonSimplified forecasting of tight/shale-gas production in linear flow. Unique to each well, the three Arps coefficients, qi, Di, and b, are determined by the curve fit exercise. Canadian Production. In our oil and gas report, we have translated the energy requirements of key demand sectors into the trends we expect to see across the value chain. Analog to Validate Producibility - In certain instances. However, sporadic reports of credible b values greater than one were discussed by Long and Davis2 and they proposed a modified Arps method for such cases. Lee, W. J., 2016, Chapter 6 in SPEE Monograph 4, Estimating Ultimate Recovery of Developed Wells in Unconventional Reservoirs. Incorporate well surveillance and predictive models into forecasts to improve short- and long-term estimates of ultimate recovery. North American gas production represented over 28% of total gas supply in 2019, and production in the region increases 1.5% annually through 2025 according to our forecast. This revised forecast is 140,000 barrels per day lower than the IEA's previous projection. There must be sufficient production history to reflect scheme performance and it must be repeatable to be classified as an analog. 2011. High global oil inventory and surplus oil production capacity are expected to limit oil price increases in 2021. The DEA uses this consumption forecast together with its oil and gas production forecasts to determine whether Denmark is a net importer or exporter of oil and gas. The report projects a constrained outlook for Canadian oil production from 2019 to 2035. EIA forecasts that global consumption of petroleum and liquid fuels will average 92.4 million b/d for all of 2020, which is down by 8.8 million b/d … The DEA uses this consumption forecast together with its oil and gas production forecasts to determine whether Denmark is a net importer or exporter of oil and gas. DR. JOHN SEIDLE is a Partner and Senior Reservoir Engineer with MHA Petroleum Consultants LLC in Denver, Colorado. Monday - Friday, 08:00 - 17:00 CST (-6:00 GMT), With little regard for reservoir physics, reservoir engineers began predicting future, A plot of the Arps equation fit to production data is shown in Figure 1. Electric vehicle outlook to 2040. The Novi solution uses predictive analytics built on oil & gas data to drive dynamic per-well type curves for oil, gas, condensate and water that scale automatically for completion designs and spacing considerations. Richardson, Tex: Society of Petroleum Engineers. We discuss how the oil and gas energy system will meet this demand from existing and new production capacity. If you are interested in learning more about advanced decline curve analysis and reserve estimation techniques, we recommend enrolling in the following related courses. The EIA forecasts that WTI prices will average around $38/b in 2020 and $44/b in 2021. No production tests were done on the deeper reservoir but log and core data were taken, along with a wireline fluid sample.” The comparative data from Jonathan and Macintosh Fields are contained in Table 1. Sometimes, especially in the exploration and appraisal stages, it is necessary to develop a range of production forecasts for a project based on very limited data, often in the absence of flow information for that particular field,. Arps hyperbolic decline curve fit to data. https://petrowiki.spe.org/index.php?title=Production_forecasting_analog_methods&oldid=52802, Copyright 2012-2020, Society of Petroleum Engineers. Decline curve analysis (DCA) is a graphical procedure used for analyzing declining production rates and forecasting future performance of oil and gas wells. This statistic shows the oil production capital expenditure worldwide by region from 2010 to 2014, with forecasted figures for 2015 to 2021, in billion nominal U.S. Legacy gas production was also projected to … After 2030 exports to the US grow due to the decline in production from their maturing shale fields. CAPP publishes a number of reports on a variety of topics related to Canada’s oil and natural gas industry, such as the Crude Oil Forecast and our six-part Economic Series. The forecast worksheet displays production forecast analyses in a table. Jill Feblowitz IDC Vice President, Utilities and Oil and Gas • Data size and complexity. The AUTOREG procedure estimates linear regression models when the errors are autocorrelated. EIA expects crude oil production in the Lower 48 states will increase from 8.7 million b/d in February 2021 to 9.1 million b/d in December 2021, as drilling increases in response to rising oil prices. The U.S. Energy Information Administration (EIA) has raised its Brent and West Texas Intermediate (WTI) oil price forecasts for both 2020 and 2021, its … It was estimated that the well was producing from a different pool and it was dropped because the EUR significantly inflated the EUR for the target reservoir. Multiple PetroSkills classes extend this brief introduction to include wells producing gas or condensate, discuss other decline methods for unconventionals such as the Duong and stretched exponential decline models, and introduce methods to detect well interference, reservoir pressure dropping below bubble point or dew point, and diagnostic methods to determine flow regime. Click the infographic below to get a glimpse of our integrated research. Mon, 12/02/2019 - 08:00 AM. We've paired our proven authority in macro oil forecasting with unrivaled expertise in power and renewables, metals and automotive sectors. Gulf of Mexico OCS Region. Other important rate-dependent parameters include reservoir pressure and gas oil ratios, which can also be used to compare potential analogs in most petroleum systems. Society of Petroleum Engineers. The NPD’s forecasts show that oil and gas production, following a slight decline in 2018/2019, will increase during the period from 2020 to 2024. A different field contained fewer wells but a candidate for analog comparison was one township lateral distance away from target reservoir. We also consider implications for LNG and pipelines, and the roles digitalization and emerging technologies will play across the value chain. Improve Oilfield Production Forecasting With Predictive Analytics For the oil and gas industry, production forecasting is a highly complex task, and as such requires an advanced analytical engine to achieve robust forecasts. Arps hyperbolic plots typically. Legacy gas production was also projected to … The task of identifying analogous reservoirs in petroleum systems requires active collaboration between geoscience and reservoir engineering. Offshore activity in these two nations should rise 16.4%, to 85 wells.
