Natural Gas Production
Searching for Natural Gas
Companies typically perform seismic studies to learn about formations most likely to hold recoverable natural gas, and may drill exploratory wells to confirm the results of these studies.
Companies can make educated guesses about which tracts of land within a field hold recoverable natural gas. Before making large financial investments, however, they typically perform seismic studies that help in characterizing the size, shape, and depth of the formations most likely to hold recoverable natural gas. The use of 3-D seismic technology to image subsurface rocks increases geologic knowledge, improves drilling accuracy, and lowers risks in exploration.
Seismic studies involve the detonation of explosive charges to create vibrations and sound waves that move through underground formations. The sound waves are subsequently reflected back to surface receptors. Some of the elements in a seismic study include:
Company geologists use the results of the seismic studies to predict the optimal locations for siting the wells. In areas with previously established production, production wells can be drilled directly. However, in some cases, before embarking on a full-scale drilling program, the companies may drill one or a few exploratory wells that are used to confirm whether the targeted formations hold economically viable resources.
Drilling an exploratory well involves essentially the same process as drilling a production well. The production well drilling process is described in the next section.
