New Low for Active US Crude Oil and Natural Gas Rigs
In 2 months, the US saw a 56% decline in rig count, reaching a 33-year low.
Life After 5: How Tight-Oil Wells Grow Old
Production data from the oldest horizontal wells in the three largest oil plays in the US show that annual decline rates remain relatively high for a long period of time. This challenges assumptions held about production after 5 years and directly affects reserve and ultimate recovery estimates.
ConocoPhillips Leaning on Conventionals Near-Term, Unconventionals Long-Term
Most of ConocoPhillips’ oil and gas production by the end of the next decade will come from its unconventional operations. But, for the near-term, the Houston independent will rely on conventional assets as it seeks to keep spending in check, decline rates low, and cash flow on the rise.
Equinor Exits Eagle Ford JV
Spain’s Repsol will assume 100% interest in and operatorship of the joint venture as Equinor leaves the 9-year partnership.
Texas Regulators Say Yes to Flaring Over Pipeline Company’s Objections
Texas regulators rejected a rare challenge to gas flaring in the state after an oil company argued that a flaring ban would force it to shut in wells, damaging the reservoir and reducing future oil production.
Shale EOR Delivers, So Why Won’t the Sector Go Big?
There is every reason to believe that enhanced oil recovery through huff-and-puff injections in US tight-oil plays could be a technical success across large numbers of wells. However, widespread economic success remains uncertain.
Integrating Geomechanical Data Optimizes Completions Design
This paper demonstrates how engineers can take advantage of their most-detailed completions and geomechanical data by identifying trends arising from past detailed treatment analyses.
Viability of Gas-Injection EOR in Eagle Ford Shale Reservoirs
This paper studies the technical and economic viability of this EOR technique in Eagle Ford shale reservoirs using natural gas injection, generally after some period of primary depletion, typically through long, hydraulically fractured horizontal-reach wells.
Huff ’n’ Puff Gas-Injection Pilot Improves Oil Recovery in the Eagle Ford
The Eagle Ford formation has produced approximately 2 billion bbl of oil during the last 7 years, yet its potential may be even greater. Using improved oil-recovery (IOR) methods could result in billions of additional barrels of production.
BP To Buy US Shale Assets From BHP for $10.5 Billion
BP ends a year of speculation as to who will buy BHP Billiton’s much-coveted US unconventional business, transforming its Lower 48 portfolio in the process.
Double-Digit Growth Forecast in US Drilling and Completion Market
Drilling and completion expenditure and activity is projected to show multiyear double-digit growth from 2018–2022 despite a flattening of rig count increases.
Shale EOR Works, But Will It Make a Difference?
The promise of getting 30% more oil production from shale wells has set off a race by companies trying to see if they can replicate what EOG has done. But the big question is: Can it add enough oil to increase the industry’s low average recovery rate?
Tool Developed for Modeling Space Between Aquifers and Wells in Eagle Ford
A 3D conceptual model developed by ConocoPhillips helps to outline the company’s water usage for hydraulic fracturing operations in the Eagle Ford.
Data and Digital Hold E&P’s Future, Says New Century CEO
Leveraging data to drive the best technology solutions and inform business strategy is the route to future industry success, says a US independent’s top executive.
Drilling Improvements Work Toward the Perfect Well in the Eagle Ford
In the Eagle Ford, an integrated approach to engineering and operations was key to optimize performance and improve understanding of the area.
Production Performance in the In-Fill Development of Unconventional Resources
This paper presents results from the analysis of the effect of in-fill drilling on parent-well performance, and describes a simplistic approach to understanding the effect of the quest for operational efficiencies and economic cycles on development strategies.
Applying Lessons Learned To Minimize Overall Investment in Unconventional Plays
This paper provides a retrospective assessment of the Barnett and Eagle Ford Shale plays to highlight lessons learned and the associated value of those learnings.
Unconventional Technology Gains Exceed Expectations, but Low Prices Offer a Stern Test
Oil markets displayed their manic-depressive side in August, dropping to around USD 40/bbl early and jumping back to near USD 50/bbl at month’s end.
Eagle Ford Shale Well Control: Drilling and Tripping
The authors describe the development of well-control techniques that allowed successful drilling operations in the Piloncillo Ranch lease in south Texas.
A Novel Completion Method for Sequenced Fracturing in the Eagle Ford Shale
Evenly fracturing all clusters in heterogeneous zones is challenging in long horizontal sections penetrating heterogeneous reservoirs, as is often the case in the Eagle Ford shale.
Unconventional-Asset-Development Work Flow in the Eagle Ford Shale
This paper presents a pragmatic integrated work flow used to optimize development and guide critical development decisions in the Black Hawk field.
Production Analysis Couples Multivariate Statistical Modeling and Pattern Recognition
The purpose of this paper is to apply multivariate statistical modeling in conjunction with geographic-information-systems (GIS) pattern-recognition work to the Eagle Ford.
