Explanation of Acoustic Wave Propagation Monopole compressional and shear Compressional and shear waves (sometimes referred to as p- and s-waves) are excited in the formation, along with various modes in the borehole, by a monopole source operating at high frequencies (typically 10-20 kHz). They propagate as body...
Depth correlations and core-log integration Total gamma-ray log curves, which are acquired with every toolstring combination, are normally used to depth match all of the logsobtained in any one hole. The HSGR log from the Triple Combo is used as the base curve, and the SGR...
Description The BHC sonde measured the time required for a compressional sound wave to travel through one foot of formation. The BHC consisted of an upper and lower transmitter arranged symmetrically on either side of two pair of receivers. The spacings T1-R2 and T1-R4 were 3 and 5 feet apart, as well...
Description The Array Seismic Imager (ASI) consisted of an array of five seismic shuttles linked by a bridle to a signal-conditioning cartridge. Each shuttle sensor package contained three mutually orthogonal geophones fixed relative to the sensor package geometry. One geophone lay along the axis of the package (z-axis); the other...
Description The APS sonde is the key module in the Integrated Porosity Lithology system components. The electronic neutron source (minitron) allows epithermal neutron measurements and detector shielding, resulting in porosity values that are less influenced by environmental conditions. The near-array ratio epithermal porosity is the primary...
Description The Borehole Geometry Tool Kit (Schlumberger Seismos Prakla VSP Tool) was a three-component VSP tool that was used for many years in the petroleum exploration industry. At the time of its deployment in ODP, it was the slimmest available Schlumberger 3-axis VSP tool. Each of the...
Description The WST-3 was a Schlumberger three axis check shot tool for both zero offset (chef shot) and offset vertical seismic profiles (VSP). It consisted of three geophones that pressed against the borehole wall and recorded the acoustic waves generated by an air gun located near the sea...
