US oil production is getting lighter and gas production is spreading as unconventional formations feed export growth.
IEA Sees No End to US Shale Output Surge
The scheme by OPEC and non-OPEC producers to collectively curb oil production has brought stability to the global market—which, as a result, could soon be awash in “a second wave” of US shale output growth.
Innovation Will Drive Shale Survival
How can operators and service companies go forward in a shale-dominated industry with low oil prices?
3D Full-Field and Pad Geomechanics Models Aid Shale Gas Field Development in China
The oilfield-development plan (ODP) for a shale gas field at the southern edge of the Sichuan Basin in China started in early 2014.
Energy Panel: Efficiency Focus Still Necessary in an Era of Transition
Despite optimism in a shift from “lower for longer” oil prices, industry executives stressed the value of maintaining efficient operating practices.
Integrated Completion Sensitivities for Horizontal-Well Design in the Vaca Muerta
The boom in organic shale plays has revealed the critical need to size hydraulic-facture treatments correctly to achieve commercial success.
BHP Billiton Plans To Divest US Onshore Assets
BHP Billiton plans to divest its US onshore assets. The company will continue to complete well trials, acreage swaps, and look into midstream solutions to increase the value, profitability, and marketability of the assets.
Natural Fractures Add Little to Shale Gas Reservoir Productivity
Senior Research Scientist and SPE Distinguished Lecturer Ian Walton uses a semianalytic shale gas production model to show that natural fractures, contrary to the intuitive beliefs of many, do not contribute significantly to production.
IEA: US May Be Top LNG Exporter by 2022
One of the world’s leading energy watchers says the second shale revolution will come in the form of LNG exports.
Offshore Drilling Market: Recovery by 2020s?
An analyst from Rystad looks at the state of the offshore drilling market and the likelihood of recovery by 2021.
Steerable-Drilling-Liner Technology in Unstable Shale
Challenging environments such as unstable clay formations represent high operational risk when running tubulars after drilling is completed.
Conditioning Mature Vertical Wells To Stimulate and Test Shale Productivity
One of the most promising targets for resource-rock stimulation in South America is the Vaca Muerta (VM) shale in western Argentina.
Shale Industry Needs to Look Within for Solutions That Save
At the recent 2015 Unconventional Resources Technology Conference, a major theme was how companies can improve performance without increasing the size of their budget.
Refracturing With Expandable Steel: A Stronger Alternative to Chemical Diverters?
Enventure Global Technology is working to convince operators that its solid expandable steel liners perform better than chemical diverter agents for refracturing operations. Its technology is called the ESeal ReFrac Liner.
Oil Price Plunge Requires Revised Completion Methods
In this cost-cutting market environment, completion engineers face added pressure to maximize the return on every dollar invested when putting unconventional wells into production.
Effects of Infill- and Offset-Drilling Patterns on Field Development for Shale Wells
In this paper, the effect of timing and pattern of well placement on NPV is studied. Three scenarios were evaluated.
Thermoelectric Nanomaterial Improves Shale Stability
Large amounts of clay minerals are present in shale; shale’s resulting instability is a major problem while drilling.
Combined Geostatistics and Bayesian Updating Optimize Drilling in Shale-Gas Plays
The development of an economically efficient drilling program in shale-gas plays is a challenging task, requiring a large number of wells; even with many wells, the average well production and the variation of well performance (economics) remain highly uncertain.
Factors Critical to Multiwell Reservoir Simulation of Liquids-Rich Shale Plays
Multiwell modeling of shale plays is not performed frequently. In projects in which a main objective is well spacing or completion optimization, a comprehensive multiwell reservoir-simulation study is required.
Molecular Simulation Helps Determine Key Shale-Gas Parameters
Shale gas is fast becoming a source of energy of paramount significance for the coming years. Although commercial production has been achieved in numerous plays throughout the world, the actual physics involved is poorly understood.
