Abstract

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.
