“…Ever since the first commercial multichannel seismic digital recorder came into use in the late 1960s with 24 channel capabilities -the DFS-1 by Texas Instruments with support from Mobil and Texaco (Laster, 1985), the huge data acquisition rates of marine seismic vessels have rendered it nearly impossible to achieve real-time processing of seismic data at sea. Modem marine systems commonly employ 240 or more channels at 2 millisecond sampling rates which calculates out to 120,000 amplitudes recorded every second.…”

In the fall of 1990, Texaco completed an innovative 4,300 km seismic program which included processing, interpretation of stacked and even some migrated-stacked sections of key lines. One of the new lead areas of complex block faulting was identified, infilled and, after final office-based interpretation of the entire data set, matured into a drillable prospect. By using this unconventional technology, Texaco saved the time and expense of mobilizing a second survey to mature new leads and furthermore, it allowed the explorationist a chance to begin the block evaluation process months ahead of schedule as good quality (albeit not final quality) record sections were made available hours rather than weeks after data collection.

Two key technological developments in petroleum exploration - three dimensional seismic survey (3-D Seismic) and integrated seismic interpretation workstations - have led to significant discoveries of oil and gas in the various Nigerian oil provinces where they have been introduced. These new technologies were introduced in Nigeria in the mid-1980s and have since resulted in significant additions to the country's proven crude oil and natural gas reserves.

The last ten years have seen an evolution in the state of the art for seismic data processing on a number of fronts. Data transformations investigated have made some types of analyses much more straightforward. Deconvolution has become a sophisticated process which includes statistical, model‐based, and deterministic methods. Vibroseis® processing has led to a greater understanding of the statistical limitations in recovery of the wave‐field amplitude from sign‐bit recording, and the deconvolution of Vibroseis data has improved. Multichannel filtering and analysis in transform domains have resulted in increasingly effective tools for noise reduction and signal enhancement. In statics analysis, surface consistency as a constraint remains a standard, and refraction analysis has become popular as a means of preconditioning data for residual statics estimation. Advances in stacking methodology have come mainly from addressing three effects: ray bending through lateral velocity variations, complex structure, and source‐receiver azimuth variations. Recently many techniques of interpretation processing have been introduced with the goal of improving the estimate of earth properties, rather than generating a stacked or imaged section of higher fidelity. The interaction among related disciplines has increased and this serves to amplify the effectiveness of each discipline because they are now developing in less isolation.
