Title: Shallow Geothermal Survey of Durkee Oil Field and Woodgate Fault, Harris County, Texas: ABSTRACT

Author(s): Loran D. Ambs

Article Type: Meeting abstract


This study was conducted northwest of Houston, Texas, in two areas of intensive investigation: Durkee oil field and a nearby segment of Woodgate fault. Temperature measurements made with thermistors at a depth of 2 m revealed temperature anomalies caused by sources at depth and in the near surface.

At Durkee oil field, a cool anomaly of about 1°C was found to be caused by a reverse drag fold at a depth of about 6,000 ft (1,829 m). Two warm anomalies of about 1°C were found to be the result of two distributary channel sands at 7,000 ft (2,134 m) depth. Another warm anomaly of about 1°C and perpendicular to the channel sands was found to be the result of a fault intersecting the surface.

Where Woodgate fault possessed a scarp, a temperature maximum was found directly on the scarp. Where no scarp was visible, temperature measurements made at 2 m depth were successfully used to trace the fault and some of its associated fractures. The shape of temperature anomalies on and near the fault were found to be related to the pattern of ground-water flow in the area.
