The most challenging aspect is using hydraulic fracturing (fluid availability and management, fracturing fluid and proppant selection, fracturing design, equipment) as it incurs the highest...

... permeability of the Upper Baharyia reservoirs are the primary challenges to maintaining economic well productivity. The interest in developing low permeability reservoirs stems from favorable economics attributed to advancements in horizontal well drilling and hydraulic fracturing technology, offering methods...

... Wells of shale and tight reservoirs cannot be economically produced unless they are stimulated by a large hydraulic fracture treatment or produced by use of a horizontal or multilateral wellbores. To classify shale and tight reservoirs, the rock permeability was used to distinguish each type...

... Abstract Large, high density fracture networks are necessary to deliver commercial production rates from sub-microdarcy permeability organic-rich shale reservoirs. Operators have increased lateral length and fracture stages as the primary means to improve well performance and, more recently...

... Abstract Tight gas/tight oil reservoirs require fracture stimulation to achieve commercial rates of hydrocarbons. Fracturing operations involve pumping considerable volumes of proppant and water/gel into the reservoir. Rapid cleanup of fracturing fluids and residual proppant ensures the desired...

... to estimate how many years a well could produce and what the abandonment rate was. Other studies targeted production data analysis to evaluate the completion (hydraulic fracturing) of shale wells. The purpose of this work is to generate field-wide production forecast of the Eagle Ford Shale (EFS...

...Barnett Shale Learning Curve Abstract The industry has made significant advances in the way we exploit unconventional resources such as source rock and tight reservoirs. Innovations in horizontal drilling and multistage fracturing have unlocked previously uneconomical plays, and technology...

...Quantification of Fracture Parameters Fracture dip angle Naturally fractured reservoirs contain more than 50% of the known oil and gas reserves worldwide ( Ahmed 2010 ). These reservoirs are heterogeneous and anisotropic media consisting of matrix blocks and fractures. The ultra-low...

As a result of these extensive trials, the current best practices employ many of the techniques described by Moiseenkov et al. (2013) . For example, in the middle and bottom...

... stimulation treatment techniques. Mostly, horizontal wells or multilateral wells with transverse hydraulic fractures make the feasible production rates possible, and improved performance of these reservoirs should be taken into account as much accurate as possible ( Miskimins, 2008 ). Evaluation...

... methodologies to hydraulically fractured unconventional gas reservoirs. The rapidly changing dynamic flow behavior that occurs as fluids move from poor quality reservoir to a highly conductive fracture and then feed into an infinitely conductive wellbore creates complex solutions which are difficult to fully...

... Abstract In unconventional reservoirs, the well life cycle includes drilling, completion, flowback, and production. The analysis of the fracturing pressure, flowback, and production data provides an early estimate of the stimulated rock volume (SRV) and reservoir flow capacity. In this paper...

... Abstract The early development of a systematic approach to well completion practices centralized around multistage hydraulic fracturing treatments is often the critical component to sustainable reservoir exploitation and development. Unfortunately, the exploitation of either exploratory...

... Abstract This paper details the successful downhole microseismic monitoring of a number of hydraulic fracture treatments in a horizontal well drilled in the Barik reservoir, integrating the results with treatment data. The treatment well was drilled in a direction of 312°, at 90° to the assumed...

... Abstract During the past decade, the combination of hydraulic fracturing and horizontal wells, has proven to be the key, to the unlocking of unconventional plays across North America and elsewhere. This efficiency has been accomplished by using two very distinct completion approaches: the Plug...

The only other fracturing technique that had not yet been introduced to the Amin formation was a High Rate Water Frac (HRWF, also known as a Slickwater (SW) frac). This technology, widely used in North America...

... Abstract Microseismic data were acquired during the hydraulic fracture stimulation of a horizontal well in the Cotton Valley tight gas formation in east Texas, U.S.A., using a borehole observation array. The ~3700 feet horizontal well was successfully stimulated in six stages using slickwater...
