Abstract

​

Hydraulic fracturing is one of the most common methods to enhance oil recovery all over the world. Taking into account changes of stress-strain properties and stresses along the wellbore calculated using well log data from correlations based on core analyses significantly improves quality of estimated parameters of hydraulic fracture geometry. This paper reviews the problem of geomechanical models incorporation into fracturing design. Several options of geomechanical modeling data adaptation have been offered to optimize fracture design. Based on engineering analyses, pilot projects have been implemented in three wells. Downhole logging, including full-wave acoustic logging, noise logging, and pulsed neutron logging with tracer injection confirmed matching between model parameters and actual hydraulic fracture geometry.

Key words:

​

geomechanical modeling, fracture design, clustering, fullwave acoustic logging, pulsed neutron logging, hydraulic fracturing
