Title: Quality improvements impact seismic business

Abstract

The introduction of 3D, and now 4D, has opened new, important applications involving more accurate reservoir delineation for reduction of drilling risk, better reserves calculation and production optimization. The latter derives from more precise location of drainholes and a clearer understanding of reservoir drainage over time. Since its early days, seismic technology has evolved on two parallel paths, acquisition and processing. With a few exceptions, acquisition--the way a wavefield is sampled--has remained the same for the past two decades. At the same time, advances in computer technology have allowed great strides in the ability to process seismic data. A new technique, called simply Q, offers 30,000 channels recordable in real time at a 2-msec sampling rate. With this many discrete channels, geophysical solutions are effectively decoupled from the hardware, providing clean, distortion-free signals to the processors. A software technique--digital group forming--allows data to be shot once and processed multiple times to achieve optimum results for each particular target. Some of the advantages of Q are described.
