A Synergistic Approach to Optimizing Hydraulic Fracturing

Abstract

Combining meawiernent, simtilafion,..m. dbnaging technologies into an integ@ted program .can help operators achieve the best hydraulic f~cture treatment possible. Hydrocarbon production can be signi@iMy increased when fractures tire extended to the planned length, and fracturing fluid is.rektined within t& zone of interest. Fractures that briali out of zbne incfesse the risk of excess water "production with the hydrocarbon. Consequefitly, the ability to select suitable operational parameters for hydraulic fracturing is critical to job SUCCS.3S.An evacuation of formitkiii piopeiti& and potenfib amiem to hydraulic fracttiijng can bc made with three-"" "dimensional (3D) simulatiori to integrate data tzken from wirelirie logs, wzveforni sonic-logs, and.microfrai measurements.

Application of Dipole Sonic To Evaluate Hydraulic Fracturing

“…Several programs 19 were developed, based on the basic rock mechanics equations developed in the 1900s, to calculate the different strength modules [20][21] and the Poisson relationship from compressional and shear travel time and the formation density (Elastic or Young Module, Volumetric Module, and Shear Module). In addition, the Mohr-Coulomb criteria is used to model the response of the reservoir to different stress conditions.…”

“…1,2,3,4,5,6,7,8,9,10 The candidate selection process evaluates the net-to-gross sand thickness ratio, reservoir pressure, and permeability for each zone. The net-to-gross ratio provides information on productive and non-productive fracture height, which is needed for inflow analysis.…”

New Petrophysical Process Improves Reservoir Optimization by Linking Stimulation Design, Reservoir Modeling, and Economic Evaluation

“…[1][2][3][4][5][6][7][8] The value of production enhancement treatments is established, and stimulation methods have advanced greatly over the years. The integration of traditional porosity and saturation petrophysical analysis, stress profiling from log-derived elastic moduli, and pay cutoffs are the reservoir parameters needed for 3D modeling.…”
