Fracturing/pressure pumping
After 5 years of in-depth diagnostic research, the Oklahoma City-based operator shares more insights on fracture behavior.
This paper discusses the development of a multientry, multistage fracturing system and its advantages over traditional openhole multistage fracturing solutions.
Two new studies from completions experts suggest the global upstream industry has a major opportunity in medium-quality reservoirs.

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. -
One of the biggest ways to lower the cost of production from shale would be to identify zones that are productive, or not, before fracturing them.
-
A service using pressure data from a few nearby unconventional wells to map fracturing will soon be for sale.
-
Two places that illustrate the mounting challenges facing the shale business are the Bakken Shale in North Dakota, where the number of working rigs is one-third what it was a year ago, and the Fayetteville Shale in Arkansas, where there are no more working rigs.
-
What is observed when an unconventional well is fractured is often at odds with what was expected by those who planned the job.
-
When it comes to hydraulic fracturing, steadiness may not be a virtue. That was the conclusion of a test to see if rapid pump rate variations would lead to greater production than conventionally fractured stages when the pressure was held steady.
-
Hydraulic fracturing exerts transient geomechanical forces near the wellbore, enabling a brief time interval in which a second hydraulic fracture can be created in a different direction.
-
A new unconventional proppant technology—a rod-shaped proppant—delivered 25% higher oil per net pay compared with offset wells using conventional proppant.
-
A refracturing campaign in the Permian yielded a production gain that allowed payback on the investment within 6–12 months.
-
The integration of microseismic data with 3D seismic attributes, and well log and completions data is used to understand geomechanical rock properties.
