seismic data capable of showing a three dimensional image of the reservoir. Strictly, 3-D is a closely spaced grid of 2-D seismic lines with interpolation to create a seismic cube. The cube can be sliced vertically to create 2-D lines or sliced horizontal

n: Schlumberger wireline tool designed to acquire multilevel triaxial seismic data in cased holes. Provides high quality seismic images in relatively close proximity to the wellbore.

n: Schlumberger wireline tool that digitizes compressional, shear, and Stoneley waveforms and is designed to minimize the discrepancies between sonic and seismic data. Used for porosity evaluation, shear seismic correlation, thin bed detection, fracture pred

a computation applied to seismic data that returns reflection events (signals) to their origin in the subsurface.

the difference in arrival times of reflected seismic data at different detectors.

adj: of or relating to an earthquake seismograph indicate the general characteror earth vibration, including those artificially induced.

an exploration technique that can find structures and potential reservoir traps by reflecting sound waves from the rock strata. [Seismic acquisition (2-D, 3-D, 4-D) – seismic data are used to map subsurface formations. A 2-D survey reveals a cross section

n pi: detailed information obtained from earth vibration produced naturally or artificially (as in geophysical prospecting).

n: The ways be used to detect the formation pressure by the different velocity of anthropic seismic wave in the formation.

n: An adjustable mechanical source that delivers vibratory seismic energy to the Earth for acquisition of seismic data. Mounted on large trucks, vibrators are commonly used for acquisition of onshore seismic data.

vertical seismic profile> Run in a single wellbore. Helps correlate logs with seismic data.
