Fracturing/pressure pumping
The Houston-based enhanced geothermal developer scored $1.9 billion in an initial public offering, positioning it to expand projects in Utah and Nevada.
A Chinese operator in the Sichuan Basin used high‑frequency pressure monitoring to evaluate frac performance in unconventional wells.
Hydraulic fracturing holds great potential in the region, but there are several key questions worth asking as efforts move forward.
-
Evenly fracturing all clusters in heterogeneous zones is challenging in long horizontal sections penetrating heterogeneous reservoirs, as is often the case in the Eagle Ford shale. -
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 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.
-
This paper discusses fracture stimulation in the first joint-venture shale-gas project with foreign companies in China.
-
This paper presents a pragmatic integrated work flow used to optimize development and guide critical development decisions in the Black Hawk field.
-
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.
-
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.
-
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.

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.
