Fracturing/pressure pumping
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 US supermajor is using one of its lowest-value hydrocarbon products to generate double-digit production increases in its most prolific US asset.
The collaboration has announced Closed Loop Fracturing, which combines real-time subsurface data with automated surface control.

This paper attempts to describe some of the common problems and to help prevent some common errors often observed in diagnostic fracture injection tests (DFITs) execution and analysis. -
Refracturing older unconventional wells is likely to reward those willing to investigate the reasons why production declines and what can be done to restore it, according to George King, distinguished engineering adviser at Apache Corp.

This paper presents a pragmatic integrated work flow used to optimize development and guide critical development decisions in the Black Hawk field.

This paper discusses fracture stimulation in the first joint-venture shale-gas project with foreign companies in China.

This paper describes a modeling technique by which hydraulic fractures are represented as part of the well model rather than as any form of refinement in the simulation grid.

Used extensively by the food, chemical, and pharmaceutical industries, the mechanical-vapor-recompression (MVR) process is viewed as a reliable method for recovering demineralized water from concentrated brines. This paper reports on performance of an advanced MVR system in north-central Texas.

A growing chorus of suppliers, researchers, and service companies is persuading US operators to re-examine their use of slickwater in shale plays and consider displacing it with carbon dioxide and nitrogen.

Pumping fracturing jobs is an equipment killer. The job requires running enormous quantities of water and sand through a pump, which is an abrasive mix that damages pumps in ways that cannot be fixed. Adding to the pressure is the trend toward clustering wells on pad sites that extend run time.

Hydraulic fracturing solutions use a gelling agent known as guar gum to transport proppant. Flowback water can have guar gum concentrations has high as 1% by volume creating treatment challenges prior to reuse or disposal.

For those in shale exploration, “fracability” is a real word, a critical property, and a point of contention.
