Production Decline Curve Analysis in the Annual Energy Outlook 2020. Release date: March 18, 2020. A key assumption in evaluating the expected profitability of drilling a well is the estimated ultimate recovery (EUR) of the well. EIA uses an automated routine to analyze the production decline curve of shale and tight oil and natural gas wells. This study derives typical production curves of tight oil wells based on monthly production data from multiple horizontal Eagle Ford shale oil wells. Well properties initial production (IP) rate and production decline rate were documented, and estimated ultimate recovery (EUR) was calculated using two empirical production decline curve models, the hyperbolic and the stretched exponential function. This study derives typical production curves of tight oil wells based on monthly production data from multiple horizontal Eagle Ford shale oil wells. Well properties initial production (IP) rate and production decline rate were documented, and estimated ultimate recovery (EUR) was calculated using two empirical production decline curve models, the hyperbolic and the stretched exponential function. Tight oil production in three of the four most productive regions (Eagle Ford, Bakken, and Niobrara) began to decline during 2015 as rig counts have fallen near or below the relatively low levels during 2009.

28 Mar 2019 EIA projects further U.S. tight oil production growth as the industry level through the early 2020s before gradually declining through 2050.

KEY WORDS: Tight oil, Shale oil, Well production, Decline rate, EUR, Eagle Ford. INTRODUCTION. Extraction of oil and gas from shale formations. 1 Feb 2020 Tight-oil production in the US set new records in 2019, but the At 5 years of age , horizontal wells in the Permian see decline rates fall to an 20 Feb 2018 The Low Oil Resource case projects tight oil growth of another million barrels per day through about 2022, and then a steady production decline

Significantly, the decline rate is highest in the producing segment that many in the market are relying on to swing higher to meet new demand: shale oil. A tight oil well can decline by up to 50

Abstract Performance prediction of wells producing from tight microdarcy These tools include (a) traditional decline-curve analysis (Arps formulation), 12 Nov 2019 The U.S. has more than doubled oil production over the past decade, and at It is worth reiterating that after an initial burst of production, shale wells decline change…the EIA's forecasts for tight oil and shale gas production Tight oil's key problem is the rapid decline in well pro- ductivity, which requires repeated drilling of wells in or- der to maintain production - Drollas L.P. (2013).5.

14 Nov 2018 The fracking of hard-to-reach oil reserves has helped the US regain its crown oil industry peaked in 1970s and was thought to be in terminal decline, has adding that it would require a tripling of US tight oil production from

28 Mar 2014 Getting that tight crude requires hydraulical fracturing, or fracking, After that, production is forecast to decline only gradually through 2040.

Although U.S. tight oil, or shale oil, is a dynamic new source of supply, investment in more In existing oil fields, production is declining – and this decline rate is

Most of this growth was due to increases in tight oil and natural gas liquids (NGLs ). OPEC production declined by 330,000 b/d while non-OPEC production 14 Nov 2019 US shale resources—light tight oil (LTO) and shale gas—provided a is that they decline quickly, such that production from individual wells 17 Jun 2019 The rig count, an early indicator of future output, has declined over the past six months as independent exploration and production companies cut
