Wellbore case study

SPE159262 – Laboratory Testing and Numerical Modelling of Fracture Propagation from Deviated Wells in Poorly Consolidated Formations

The Project

The foundation of this work was over 40 fracturing laboratory tests to measure fracture geometries for a range of well deviations, differential horizontal stresses and rock strength. The samples tested were from three outcrops with unconfined compressive strength (UCS) values ranging from 300-1000 psi. For boreholes having low deviation angles and small differential stresses a vertical single planar fracture became mode complex, with transverse turning fractures no longer aligned with the wellbore.

The Software

These laboratory results were used to develop and calibrate a new fully-3D finite element model that predicts non-planar fracture growth, using the finite element code ELFEN. The model matches the details of the laboratory tests, including the transition from planar vertical to non-planar transverse fractures as the well deviation, azimuth and stress differentials increase.
