A vertical or horizontal well producing from multiple fractures exhibits a characteristic response during production or pressure transient testing that can be used to identify the geometry of the fracture system. Both well test analysis and production data analysis methods are available, or being developed, that focus on indentifying the productive fractures using the intra-well fracture interference observed in either transient or production data. For example, in a multi-fractured horizontal well, analysis of the early-time production data can be used to approximate the number of producing fractures and the fracture geometry along the lateral.
The new interpretation methods require observing interference between fractures along a single wellbore, that is, intra-well interference. Since interference between fractures occurs relatively quickly, the analysis methods focus on matching early-time transient or production data to type curves. Both simulated and field examples will be presented to illustrate the methodology.
David P. Craig works as a Chief Engineer with Halliburton developing reservoir engineering technology and developing a prototype mathematical model for analyzing complex hydraulic fracture patterns. Dr. Craig is also the owner and a consultant for Reservoir Development Company where he developed a process for identifying, evaluating, and stimulating bypassed or ineffectively-stimulated layers in oil or gas wells. Dr. Craig earned a BS in Petroleum Engineering from Texas Tech University in 1989, an MS in Petroleum Engineering from Texas A&M University in 1991, and a PhD in Petroleum Engineering from Texas A&M University in 2006.
