Borehole Image Analysis Services

The methodology of Borehole Image Analysis involves identification of geological features on the image (fractures, tracefossils, bedding planes, lamination, breakout, facies), the spatial distribution of planar and linear elements using stereographic displays, and the projection along welltrace of the features for comparison with seismic or a 3D model.

Images may be used to reorient cores and to evaluate borehole stability, to model fracture patterns, to detect faults, and to evaluate paleogeographical trends.

Eriksfiord has in-house capabilities and top-expertise for authoritative processing of all types of commercial borehole image logs and conventional dipmeter logs, old as new. These include data from all main contractors (Schlumberger, Halliburton, Baker Hughes, Weatherford, BPB) and most local companies and may be derived from micro-resistivity, acoustic, density, gamma or other petrophysical readings of the borehole wall. Different tool types and technologies are used for different types of borehole fluids. The wells may be vertical, deviated or horizontal, requiring a sound geological insight for identification and evaluation of features in 3D space based on a hole 6 to 12 inches wide.
