shale

Challenging environments such as unstable clay formations represent high operational risk when running tubulars after drilling is completed.

One of the most promising targets for resource-rock stimulation in South America is the Vaca Muerta (VM) shale in western Argentina.

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.

At the recent 2015 Unconventional Resources Technology Conference, a major theme was how companies can improve performance without increasing the size of their budget.

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.

In this paper, the effect of timing and pattern of well placement on NPV is studied. Three scenarios were evaluated.

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.

Large amounts of clay minerals are present in shale; shale’s resulting instability is a major problem while drilling.

This article reviews methods used to understand the complexities associated with production from shale.

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.
