Fracturing/pressure pumping
Outstanding papers over the past year have addressed topics such as casing deformation, well spacing, frac-design optimization, proppant transport in the well or in fractures, integrating diagnostics from field trials, and exploring the effects of lateral length on production.
Operators from across the region met in Muscat to share how lessons from pilot programs are shaping cost, scale, and technology priorities across the region.
In this third work in a series, the authors conduct transfer-learning validation with a robust real-field data set for hydraulic fracturing design.

Hydraulically fracturing and stimulating multiple horizontal wells in sequence has been rapidly adopted by operators because of the potential for production without introducing unwanted risks. -
While storage and logistics are critical elements of the viability of water reuse, if the water chemistry is not fit for gel fracturing formulations, it will not matter how much is stored in centrally located impoundments.
-
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.
-
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.
-
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 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.
-
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.
