Abstract
A practical analysis technique for the determination of actual fracture geometry and proppant profile using a three-dimensional hydraulic fracturing simulator is presented in this paper. A guideline has been presented to properly describe the treatment interval, analyze the fracture treatments using field measured data, and to confirm the results using pressure transient tests and production data analysis. The examples illustrate that detailed description of the reservoir layers is essential to properly evaluate hydraulic fracture treatments. Application of this methodology requires the study of well logs. These logs (particularly the gamma ray and resistivity) allow the engineer to differentiate layers within the interval based on lithology and porosity. These logs are also used to estimate in-situ stress, permeability and porosity of such layer. A three-dimensional fracture propagation model that uses the detailed mechanical and fluid information from all layers is crucial for accurate analysis.
