HAYNESVILLE SHALE: HYDRAULIC FRACTURE STIMULATION APPROACH

摘要

The Haynesville Shale is an ultra-low permeability, unconventional gas reservoir located in east Texas and northwest Louisiana. High gas prices and the success of other shale-gas plays have led operators to invest highly in this resource play. It has great potential for development by applying the new technology available in the oil and gas industry today.Hydraulic fracturing is necessary to realize the potential of this reservoir. The nature of the formation requires that it be addressed on its own merits and not considered an analog to other shale reservoirs. Therefore, common fracture-stimulation treatments might not lead to the optimum production results. A critical evaluation of the target zones and the boundary layers is recommended for an accurate treatment design using available fracture simulators. An understanding of the formation characteristics and how they impact the development of fracture geometry and proppant placement can lead to improved success.This paper reviews the design process and technologies that are recommended to achieve the best production results. Examples of fracture-design output are presented to illustrate the following:Fluid systems and additives Proppant recommendations Design approach .
