Loren and Associates, Inc.

Problem
Errors in well logs make them not match the seismic data, making advanced seismic analysis very difficult to use.

Solution
Purify the log curves using the industry-leading Loren method. Open the door to excellent synthetic seismograms, wavelet extractions, AVO, inversion, geostatistics, and other advanced techniques.

Method
The Loren method of purification is unique: it relies on the redundancy between curves to establish a network of equations relating the variables. Zones with erroneous data are exposed, because they violate the equations. The erroneous values can be replaced by calculated values. We use nonlinear regression to calibrate the equations for local conditions, and human judgment to select the zones.
