... in Mokhtari's setup and reservoir pressure in subsurface applications). Hoang et al. (2011) present a thermo-hydraulic model for the wellbore and reservoir for a perforated completion and account for the fluid leakage to the reservoir from the wellbore during a hydraulic fracturing treatment. However, they do...

... Abstract Lately, the United States of America has experienced tremendous growth in shale plays development. To date, more than 5,000 wells have been drilled and completed in more than 20 fields. Worldwide, exploration and development of shale plays has also increased. Currently, due to low gas...

... of these reservoirs. Recently, the slot-drill (SD) completion technique was proposed as an alternative treatment method in such formations ( Carter 2009 ). This paper documents the results of a comprehensive numerical simulation study conducted to evaluate the production performance of the SD technique and compare...

... Abstract Completion programs for hydraulic fracture stimulations are planned to optimize the spacing of wells and perforation clusters such that the largest volume of the reservoir can be accessed through the promotion of a discrete fracture network in the reservoir. Such treatments also seek...

... Abstract Determining the optimal number of wells for infill drilling in an unconventional reservoir is a critical endeavor for shale gas operators as many leases are held only by production. To develop a given section, operators must select locations and completion designs for all wells...

... efficient and less resource intensive. This paper compares open hole multistage fracturing systems (OHMS) and cemented casing, "plug and perf" (CCPP) completions and presents the evolution of completion methods utilized in the Marcellus Shale. Production results from horizontal wells in two counties...

... resistivity and porosity, which in many cases may not have been previously economical to obtain in lateral wells, can now be used to delineate the needed basic reservoir properties for planning completions and future drilling designs. The method employs a newly engineered ultra slim toolstring...

... presents the successful execution of a multi-interval fracture-stimulation treatment for a long-lateral horizontal completion in the Bakken shale using a state-of-the-art hybrid coiled-tubing (CT) system and hydrajet-assisted fracturing (HJAF) technology. The new approach incorporated the following...

... Abstract Horizontal well completions in the Granite Wash formations of the Anadarko basin in Western Oklahoma and the Texas Panhandle approximately doubled year on year since 2006. During this period, the evolution of horizontal well completion and stimulation practices coupled with diligent...

... Abstract There have been over 14,000 wells drilled and completed in the Cotton Valley sand of east Texas and north Louisiana, with more than 7,900 drilled and completed since 2003. (IHS 2010) All of these wells require multistage hydraulic fractures to economically produce. Well over 180...

... Abstract Horizontal well technology is now considered a standard completion practice in unconventional gas reservoirs. With significant improvements in the drilling and completion technology, many tight gas and shale gas prospects have become economically viable. Optimizing location...

... Abstract Across many shale plays in North America, operators ask why production performance disparities exist among horizontal wells. For example, even though drilling and completion practices of a neighboring operator may be mimicked, significantly different production results are frequently...

... of the available completion technologies have been implemented with varying success, and a better understanding of reservoir performance has been linked with an increase in fracture stage capacity to drive the evolution of completion methods. This paper exclusively addresses horizontal, multi-stage completions...

... Abstract Drilling horizontally and hydraulic fracturing is becoming the well type of choice in ultra-low permeability sands and shale. However, as the complexity of these wells increases, the challenge of evaluating the effectiveness of these completions proves more problematic. The reason...

... Abstract Accelerating the learning curve in a fluvial tight-gas development program can be achieved by understanding the impact of reservoir quality and completion properties on well productivity. Too often completion changes are made over a small sample (statistical) wherein numerous...

... Abstract Traditional shale formations are presently being produced via horizontal well completions. These horizontal wells consist of numerous selectively stimulated stages containing as many as 20 stages spread out across 2000 ft to 9000 ft interval. The well completions have been stimulated...
