Seismic Acquisition in Alaska’s Cook Inlet

摘要

In March/April 2011 Apache carried out an extensive series of seismic acquisition tests in Cook Inlet, Alaska, to evaluate the feasibility of large-scale, year-round 3D seismic acquisition in Cook Inlet, and to look at the effectiveness of a nodal or autonomous seismic recording system compared to a conventional cable-telemetry system. An 18-mile seismic line starting onshore, crossing the tidal mudflats, and extending into the deeper water of Cook Inlet was acquired using multiple onshore and offshore source, receiver, and instrument types to establish the viability of a large-scale regional 3D survey and the optimum source parameters for such a program. The location of the test line is shown in Figure 1.
