... to increase production by increasing the contact area of the producing interval. Subsequently, it became apparent that wellbore contact alone was not always sufficient for providing production increases expected, thus requiring multistage hydraulic fracturing (MSHF) stimulation treatments to achieve...

... allow the classification of the reservoir as a tight gas sand. The variability of reservoir properties, both spatially and vertically, makes it difficult to standardize perforation and fracture stimulation design which, in turn, complicates delineation of a development plan for the project. One...

... 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...

... hazard. The improvement in corrosion inhibitors makes the use of a strong acid as high as 28 wt% HCl possible. The acid reaction rate can be controlled by increasing acid viscosity using gelling agent or emulsifying acid droplets, acid-in-diesel emulsion. While the issues of stimulation acids reaction...

... Abstract The careful planning and successful execution of a multi-stage fracture stimulation completion in one of the first horizontal wells drilled in the Amin Formation instigated a step change in initial production rate and long term deliverability from this tight gas sandstone reservoir...

... 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...

... Abstract The Geesbrug-1 well was drilled in 1992, and perforated and tested in 1993. The production was considered uneconomic at the time. In 2009, the well was re-completed for fracture stimulation. Three horizons were targeted, the Rotliegend, Dalen and Hardenberg. Two propped fracture...

..., we discuss the results of evaluating if we can successfully apply shale-like stimulations in developing and improving the performance of extremely low permeability tight gas reservoirs. The focus of the study is on doing sensitivity model runs to investigate the effects of reservoir permeability...

... in each leg, with average stimulation pressures up to 9,000 psi. Multilateral solutions provide the means to work within a limited surface access, generating a reduced footprint while draining a much larger volume of the reservoir from a single-surface location. This poses a significant advantage when...

Most of the wells are deep (TD >5000 m TVDbdf [>16,000 ft TVDbdf]), in H P/HT (High Pressure/High Temperature) environments (even extreme HT >175 °C [350 °F] in some cases, Maldonado et a l. 2006 ) and need to be stimulated by hydraulic fracturing in several stages for evaluation...

... Abstract For many years, the industry has relied on cemented and perforated liners to complete multistage stimulated oil and gas wells. However, the boom in tight oil and gas plays in North America and elsewhere have seen the emergence of open hole multistage system completions as a competitor...

This paper presents results from a sensitivity study of the dimension of hydraulic fracturing stimulated reservoir volume (SRV), matrix and propped fracture permeability which is spatially varied as one of the most realistic approaches, and of the bottom hole pressure.

... Abstract Deciding on the optimum spacing between fractures and selecting the optimum fracture treatment parameters is a key challenge in designing the hydraulic fracture stimulations of Unconventional Gas and Liquid Rich Shale (UGLRS) wells. To make those decisions more effectively and more...

... Abstract Optimization of fracture stimulation treatments in BP's giant Wamsutter Field is an important aspect of efficient and viable development of this tight gas asset. This paper integrates historical fracturing data, well performance, surveillance data, and data from fracturing field trials...

... Abstract Combining production from multiple intervals within a well during completion has been used for many years. Many of these reservoirs required hydraulic-fracture stimulation, and a number of promising fracturing methods have been developed where several stages can be performed...

... in stimulation on OOGCF: Viscoelastic self-diverting acid (VSDA). Based on viscoelastic surfactant, VSDA initially has low viscosity. However, while the acid spends, the fluid viscosity increases, redirecting flow to less permeable zones. After the treatment, viscous VSDA losses its viscosity when it comes...
