Previous HitFieldNext Hit Productivity: Challenge to Manufacturers of Previous HitFieldNext Hit Systems

Tawassul A. Khan, E. Lynard Olsen

Three main requirements in the design of a Previous HitfieldNext Hit system help to improve seismic Previous HitfieldNext Hit productivity: (1) fast execution time, (2) simultaneous execution of several unrelated tasks, and (3) capability of multi-function recording. Multi-function recording relates to the various options available that provide multiple choices of using seismic sources, receivers, arrays, Previous HitdataNext Hit transmission, and Previous HitdataNext Hit-processing methods. These features allow one to use the recording system to the best advantage under changing geologic and Previous HitfieldNext Hit conditions. Faster execution time is necessary when dealing with large numbers of channels and high sample rates. Simultaneous execution of Previous HitdataNext Hit transmission, Previous HitdataNext Hit processing, monitoring, and quality control are needed for a realtime recording system. Multi-function recording provides capabilities like multi-functions (receiver, source, array, weight, correlate, etc) that have been specifically developed to provide considerable improvements in the Previous HitfieldNext Hit production.

Using the multi-receiver method, one can record two, three, or four times the Previous HitdataNext Hit corresponding to the ground stations in relation to the number of Previous HitdataNext Hit channels being transmitted to the system recorder. For Previous HitexampleNext Hit, using a Previous HitdataNext Hit encoding technique, geophone outputs from 240 or 360 ground stations can be transmitted using only 120 Previous HitdataNext Hit channels. Realtime decoding in the system recorder separates the Previous HitdataTop belonging to each ground station and outputs the original 240 or 360 seismic traces to the final tape. Similarly, the Multisource method uses different source encoding techniques that can be decoded in real time to provide higher CDP fold or multiple line recording.
