Fracturing/pressure pumping
This paper describes an alternative lower-completion concept for developing Lower Wilcox reservoirs referred to as high-angle multifractured well design.
The SPE International Hydraulic Fracturing Technology Conference and Exhibition opens with calls to adapt technology while addressing regional realities.
Casing deformation has emerged as a major challenge in China’s unconventional oil and gas fields, prompting the development of new solutions to address the issue.
-
The paper presents a case study of fracture interaction mitigation in a multistage horizontal stimulation of an offshore Black Sea well. -
This issue marks the debut of the Hydraulic Fracturing Operations feature in JPT. While hydraulic fracturing has long been a feature topic, this year, we are branching this major area of interest into both this feature and a Hydraulic Fracturing Modeling feature, which will appear in the November issue of the magazine.
-
The authors have investigated the effect of perforation hole size, geometry, and shape on the coefficient-of-discharge value at ambient conditions and with backpressure, before and after sand erosion.
-
A growing volume of free data and reports from US shale fracturing test sites is available, with more on the way.
-
A major issue facing many production engineers is sand management. There are many obstacles equipment hasn’t historically been able to overcome and prolonged use is costly.
-
A lot has been learned about shale, but those working to eke out oil from that ultratight rock still extract more value from data than physics.
-
Schlumberger talks about options for improving remote operations of the many valves involved in the various activities occurring simultaneously on a multi-well pad.
-
Shale producers have learned in recent years that their fracture plugs may not be holding up as well as they thought. One of the first operators to realize the true scope of the issue is now sharing the pathway it took to solving it.
-
The supermajor would be the second to conduct a hydraulic fracturing pilot project in the country.
-
Ease of use and crowd-pleasing economics are driving US shale producers toward wet-sand completions. Chesapeake Energy is among the latest converts and explains why it wants to use wet sand on every new well.
