Eagle Ford Shale

In the Eagle Ford, an integrated approach to engineering and operations was key to optimize performance and improve understanding of the area.

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.

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.

Although refracturing is a topic that has gained a lot of interest, many shale producers have been sitting on the sidelines because early results did not justify the spending

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.

For the past several years, automated drilling has promised to deliver major improvements in drilling performance. But the technology is facing new obstacles that might affect its progress and commercialization.

For the past quarter of a century, underbalanced drilling (UBD) has been a niche technology known to many and practiced by few. It has seen acceptance in the North Sea, where UBD is used to drill through depleted reservoirs.

As shale operators look for ways to survive amid the current downturn in oil prices, accelerating the refracturing of older horizontal wells is turning into one of the most attractive options.

The authors describe the development of well-control techniques that allowed successful drilling operations in the Piloncillo Ranch lease in south Texas.

Hydraulically fracturing and stimulating multiple horizontal wells in sequence has been rapidly adopted by operators because of the potential for production without introducing unwanted risks.
