Fracturing/pressure pumping
This case study from ARC Resources and DarkVision outlines the use of acoustic imaging tools in two active fracturing programs in Canada to monitor well casing deformation.
The creation of SPE’s Acid Stimulation Technical Section shines a light on the technique that improves injectivity and productivity. JPT talked with the chair of the new section about the importance of the technical area.
Fracture modeling continues to be used to evaluate and design novel applications, and integration with diagnostics and other forms of field-data collection are crucial to success.

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. -
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.
-
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.

AFGlobal acquired the Axon pressure pump technology and product line from Amkin Technologies, a privately held oilfield equipment and technology developer.
-
A Canadian startup company is developing a tool that uses solid rocket fuel to fracture vertical and horizontal wells without the use of water.
-
To reduce the risk of wells getting “frac hits,” Permian Basin operators around Midland created an information exchange to give them notice of nearby fracturing.
-
The boom in organic shale plays has revealed the critical need to size hydraulic-facture treatments correctly to achieve commercial success.
-
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.
