Fracturing/pressure pumping
This case study presents a procedure in which the operator compared production from wells with adjusted wettability to a control group, finding that the adjustments resulted in significant improvements in production and reductions in produced water.
Output is rising fast in the South American shale play and putting Argentina on a course to soon reach 1 million B/D.
This paper presents findings reinforcing the argument that acid fracturing is a strong alternative stimulation method to improve productivity in the Austin Chalk formation.

Widely held images of what happens when a well is fractured often bear little resemblance to what actually happens underground. -
Stanford geoscientists have found a way to detect thousands of tiny tremors around hydraulic fracturing operations that could serve as predictors of eventual larger earthquakes.

SPE Distinguished Lecturer Dan Tormey will present his peer-reviewed study of the environmental effects of hydraulic fracturing during a Web event scheduled for 8 March.

Schlumberger and Weatherford called off a joint venture, with Schlumberger buying Weatherford’s US fracturing assets outright.

Fracturing reservoirs effectively can be like boxing. Moving in close enough to land a powerful punch often means a fighter has to take some hits. To effectively develop all the productive rock in a lease, new wells are drilled as close as possible to older ones, making frac hits inevitable.

Secrecy lies at the heart of invention and capitalism to reward innovators with exclusive rights to their creations. But that secrecy can also come at a cost. With drilling and fracturig, the ingredients and chemicals used to obtain oil and gas are legally allowed to be kept confidential.

The effect of frac hits on production economics is becoming more important as a result of the high-speed drilling in the US shale sector. Recent research reveals the financial and recovery risks involved if well spacing results in well-to-well interference.

A hybrid downhole microseismic and microdeformation array was deployed to monitor fracture stimulation of a vertical coal-seam-gas (CSG) exploration well in the Gloucester Basin in New South Wales, Australia, to provide more-accurate insight into overall fracture height.

The primary objective of this study is to address all known causes of productivity declines in unconventional shale gas formations with horizontal multifractured wells and to develop a fully coupled geomechanical/flow simulation model to simulate these production conditions.
