... data from some of the initial wells identified channel sands, tighter than expected, yet containing significant GIIP. Wells 7 and 8 of the first phase of drilling were completed using hydraulic fracturing to evaluate the potential for improvement in productivity and drainage from the lower permeability...

.... The polymer also incorporates functional groups that resist damage from water hardness. In addition, the polymer hydrates almost instantaneously and allows rapid viscosity generation and adjustment without a hydration unit, which greatly reduces footprint of hydraulic fracturing treatments. While this new...

... Abstract Hydraulic fracturing de-facto is the most common stimulation technique that is employed worldwide. Russia is following the same trend and most of the new and old wells are considered for hydraulic fracturing. However, eventually as more and more reservoirs become depleted operators...

... hydraulic fracturing stimulation, horizontal well drilling, and enhanced oil recovery amongst others. The vast majority of the production wells are completed with cemented 7” liners, and artificially lifted with electric submersible pumps with downhole gas separators.

... Abstract Reservoir completion techniques, such as hydraulic fracturing for low permeability wells and frac pack for unconsolidated formation treatments, are normally applied to increase well productivity. The production of treated wells can be greatly enhanced by increased propped fracture area...

... Abstract Conventional guar borate systems have historically been preferred for hydraulic fracturing applications because of the lower cost of the base polymer and crosslinker. Additionally, the fluid formulations can be easily tailored based on reservoir conditions and operational needs...

... Abstract Oil and gas productivity from shale formations can be dependent on the flow behavior of the hydraulic fracturing fluids used in stimulation treatments. Because of the unique characteristics of shale formations, including low permeability, existence of micro-fractures, and sensitivity...

... Abstract An extended-reach, S-shaped appraisal/development well drilled from a platform to prove up and drain a field extension in a Rotliegendes sandstone reservoir has been hydraulically fractured with a proppant-based stimulation treatment. The hydraulic fracture was a means to optimise...

For example, whilst hydraulic fractures may present an opportunity for significant enhancement in well performance, the fact remains...

... Abstract Hydraulic fracturing is used extensively to develop oil and gas wells in both high and low-permeability formations. Biopolymer-based fluids, including guar or guar derivatives, constitute the majority of polymers in fracturing fluids. These polymers cause formation damage, which...
