The Seitel company has made the local news recently on two accounts. First, a seismic survey worker was killed near Fairview in Marion county as part of data acquisition via rig drilling using 30 foot deep holes. And, secondly, helicopters are being used to drop supplies for similar activities involving geophone detectors and data transmission equipment. It appears from the information compiled below that this is all part of the “Cassville West” seismic data acquisition campaign of the Seitel Inc.
Seitel, Inc. Company Profile
There aren’t any “Quiet” signs in Seitel’s library, which consists of more than 43,000 sq. miles of 3-D and about 1.1 million linear miles of 2-D seismic data. The data is used to locate oil and gas. The company contracts with third-party seismic crews to gather data but handles the processing itself through its Olympic Seismic, Seitel Data, Seitel Matrix, Seitel Solutions business units. The bulk of Seitel’s total revenues comes from the acquisition and licensing of seismic data. The balance is primarily generated by its Seitel Solutions subsidiary, which gives customers access to the company’s seismic database.
Seitel, Inc. is a leading provider of seismic data and related geophysical services to the oil and gas industry in North America. Seismic data is a crucial tool in mapping the earth’s subsurface and revealing the potential for hydrocarbon accumulations. It is key to the success of oil and gas exploration efforts and to the recovery of the discovered hydrocarbons. Their products and services are used by oil and gas companies to assist in the exploration for and development and management of oil and gas reserves.
Seitel’s seismic data library includes both onshore and offshore three-dimensional (3-D) and two-dimensional (2-D) data and offshore multi-component data. Their library of onshore seismic data is one of the largest, if not the largest, available for licensing in the United States and Canada. The majority of the seismic data library covers onshore regions within North America, with a geographic concentration on the onshore and transition zone of the U.S. Gulf Coast. They conduct seismic data creation and licensing business through two wholly owned subsideries, Seitel Data, Ltd. in the United States and Olympic Seismic Ltd. in Canada.
To support the seismic data licensing business and their clients, they provide state of the art data processing services to the geophysical industry, through the Seitel Data Processing business unit. Through their Seitel Solutions business unit, they offer the ability to access and interact with their seismic data.
The currently active data acquisition campaigns include the following:
Ambridge (In Acquisition): Beaver, Allegheny & Washington Counties, PA
Horton (In Acquisition): Elk, Jefferson & Clearfield Counties, PA
Mahoning (In Acquisition): Jefferson, Clearfield & Indiana Counties, PA
Cassville West (now in acquisition), includes land in Monongalia, Marion and Wetzel counties in WV as well as land in Greene county, PA. It is presumed that this particular project includes the activities now in the news in West Virginia.
Seismic data carry critical information related to rock properties and stress, which are among the determining factors for sweet spot prospecting. Technologies are available to generate seismic attributes that can fully characterize the geology of the shale plays, including structural features, formation heterogeneity, rock prop- erties, and stress. Highly desired information such as shale brittleness and stress can be extracted from the seismic data, making seismic data more relevant in the exploration and exploitation of shale resource plays.
Shales are frequently highly heterogeneous in nature. Seismic data, with properly preserved amplitudes and sampled in the angle domain, contain information related to lithology and rock properties. Properly processed and analyzed, the seismic data are not only relevant in prospect identification but also are an important data source for well planning in a shale play. The objectives are (a) to observe shale heterogeneity by examining and analyzing different seismic attributes such as frequency-dependent attributes, structural attributes, and trace shape attributes, (b) to determine and map the shale brittleness using rock mechanical attributes such as Poisson’s ratio and Young’s modulus; and (c) to estimate stress and its orientation by deriving, evaluating, and integrating amplitude versus angle versus full azimuth and residual moveout attributes.
