Bakken Case Study: Fracturing-Plug Drillout Performance With Task-Built PDC Bit Design
A new line of specialized polycrystalline-diamond-compact bits have been tested in a series of Bakken wells. The bits’ integrated design allowed significant increases in drilling rate and the number of plugs drilled.
Permian, Bakken Operators Face Produced Water Challenges
As oil prices recover from the low point of the downturn, operators in the Permian and the Bakken are tackling water management issues.
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.
CO2-Based Enhanced Oil Recovery From Unconventional Reservoirs
In this study, detailed petrophysical and geological field models focusing on the middle and lower members of the Bakken Formation were developed.
Shale Completions Improve, Despite Shrinking Number of New Wells
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.
Designing an Optimized Surfactant Flood in the Bakken
The Bakken’s ultratight, largely oil-wet nature limits the potential of waterflooding. As an alternative, an optimally spaced well-to-well surfactant-flooding technology is proposed.
Design Optimization of Horizontal Wells With Multiple Hydraulic Fractures
The ultimate performance of fractured wells in tight reservoirs is affected severely by the interfering effects inside the fracture and interfractures.
