Fracturing/pressure pumping
Technology developers expect the tight-oil industry to give lightweight proppants another look after the Permian Basin’s biggest operator becomes an adopter.
This paper describes development of a high-temperature water-based reservoir drill-in fluid using a novel synthetic polymer and customized with optimal chemical concentrations and sized calcium carbonate.
In this case study, a geomechanics-based approach was used to create bridging and sealing at the fracture aperture using a biparticle self-degradable lost-circulation-fluid system.

Shale operators are working harder to get as much out of new wells as they did from older ones nearby. -
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.

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.
