Fracturing/pressure pumping
The Houston-based enhanced geothermal developer scored $1.9 billion in an initial public offering, positioning it to expand projects in Utah and Nevada.
A Chinese operator in the Sichuan Basin used high‑frequency pressure monitoring to evaluate frac performance in unconventional wells.
Hydraulic fracturing holds great potential in the region, but there are several key questions worth asking as efforts move forward.
-
This paper offers an alternative explanation for the early boundary-dominated flow related to dissolution of salt-sealed natural fractures in the shale. -
On the basis of production data, diagnostic methods, and field observations, it is becoming increasingly clear that induced unpropped fractures created during the hydraulic-fracturing operation play a critical role in determining the success of fracture treatments.
-
One study is showing that when pumping a proppant into a fracture, a little bit of extra effort might increase performance.
-
A long-time energy industry executive and chemical engineer has built a new water treatment system that he says can increase recovery rates from shale wells without using chemicals and will recycle all the water used in the process.
-
Openhole multistage (OHMS) systems are more cost-effective than the cemented casing plug-and-perf (CCPP) techniques for increasing production and reducing development costs.
-
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.
-
A service using pressure data from a few nearby unconventional wells to map fracturing will soon be for sale.
-
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.
-
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.
