Since 1991, GridSTAT has been used by geologists in Kern River Field to identify bad data, correct the temperature effect in resistivity logs, correlate wells, identify faults, and generate cross sections in more detail and in much shorter time. Cross sections like the one shown here are used to identify how the sands are connected between wells and to help optimize oil production. High resistivity values (>8) represents sand that contains oil. The well in the middle is a deviation well. The labels next to the well sticks are measured depths.

This is a porosity cross section generated with porosity logs and seismic impedance. A top and a base horizon markers are used. The seismic depth has been adjusted to match well logs. The seismic horizons are matched to the well markers. The seismic impedance is calibrated to porosity logs. The cokriging technique honors the well logs at well locations and weights both well data and seismic data in between wells. The variation between wells comes from the variation in seismic data. Usually there should be multiple iterations modifying the seismic picks and calibration. This section may still need more iteration.
