3.4.2. Highlights of Important Results


Perhaps one of the most important products of the Deep Source Gas program was a 140 mile (230 km) seismic reflection survey designed to describe the regional structural geology of the Washington-Oregon area and to determine the practicality of using reflection techniques in this region.

The boundaries of the study area (Figure 3.4.2) were based on a magnetotelluric survey conducted by the U.S. Geological Survey (USGS) as part of the Deep Source Gas program.

This survey delineated an anomalously conductive rock layer in an area roughly bounded by Mt. St. Helens, Mt. Adams, and Mt. Rainier. This feature, named the Southwestern Cascades Conductive Anomaly (SWCC), was interpreted to be caused by a sedimentary sequence underlying the surface volcanic layer.

Previous exploration drilling had not tested these deep sediments, but other drilling in the Pacific Northwest had found shows of both oil and gas and had led to the discovery of the Mist gas field (42+ Bcf) of northern Oregon, the regionís only commercial field.

However, most exploration activity had been conducted before the development of modern plate tectonic theory.

Both the seismic reflection interpretation and associated maturity studies indicated that the study area contained sediments potentially favorable for hydrocarbon accumulations.

The geologic model suggested by the study also indicated an extremely dynamic system that had evolved significantly over time, with complex interactions between structural formation and deposition.

In an epilogue to this study, in late 1997 Hunt Oil Company drilled a rank wildcat in Lewis County, Washington (HOC State No. 36-1). The well encountered hole problems resulting from the stress conditions existing within the subsurface, and was abandoned at a depth of 10,342 feet, prior to reaching its target depth of 15,000 ft. While some shows were reported in the well, it did not reach the depth necessary to test the potential for deeper sediments suggested by the model.
