Completion techniques in tight hydrocarbon reservoirs commonly include hydraulic fracturing (“fracing”) to increase conductivity and improve deliver-ability. Because completion techniques are expensive, often costing as much as half of the cost of a well in tight formations, it is important to understand the factors that control the fracture geometry. Improved understanding of the fracs leads to better overall reservoir management by more accurately executed treatments, identification of bypassed resources, and optimizing infill well placement for maximum reservoir drainage. All disciplines associated with the development of the reservoir: drilling, completions, reservoir engineering, geology, and geophysics can benefit from increased understanding of the frac mechanisms and resultant fracture geometry. This Jonah field study illustrates the integration of several different data types: surface seismic data, vertical seismic profile (VSP), and borehole microseismic data to determine the magnitude and direction of induced hydraulic fractures in a complex, tight-gas reservoir.

Understanding, Exploring, and Developing Tight-gas Sands
The 2005 Vail Hedberg Conference was convened to gain a better understanding of the tight-gas sand resource life cycle by encouraging a free exchange of cross-disciplinary discussion among leading scientific and engineering experts. The results of the conference have led to improved exploration models and development and completion strategies required to exploit the vast North American tight-gas sand potential and emerging international tight-gas sand plays. This third volume in the AAPG Hedberg Series is recommended for geologists and engineers involved in exploring, developing, and appraising tight-gas sand plays for a comprehensive updated view of this important natural-gas resource.
