Abstract

A method and apparatus by which fractured rock formations are identified and their orientation may be determined includes two orthogonal motion sensors which are used in conjunction with a downhole orbital vibrator. The downhole vibrator includes a device for orienting the sensors. The output of the sensors is displayed as a lissajou figure. The shape of the figure changes when a subsurface fracture is encountered in the borehole. The apparatus and method identifies fractures rock formations and enables the azimuthal orientation of the fractures to be determined.

Acoustic paramagnetic logging tool

Patent Vail, III, William B. (Bothell, WA)

New methods and apparatus are disclosed which allow measurement of the presence of oil and water in geological formations using a new physical effect called the Acoustic Paramagnetic Logging Effect (APLE). The presence of petroleum in formation causes a slight increase in the earth's magnetic field in the vicinity of the reservoir. This is the phenomena of paramagnetism. Application of an acoustic source to a geological formation at the Larmor frequency of the nucleons present causes the paramagnetism of the formation to disappear. This results in a decrease in the earth3 s magnetic field in the vicinity of the oilmore »« less

Methods and apparatus to produce stick-slip motion of logging tool attached to a wireline drawn upward by a continuously rotating wireline drum

Patent Vail, III, William Banning (Bothell, WA); Momii, Steven Thomas (Seattle, WA)

Methods and apparatus are described to produce stick-slip motion of a logging tool within a cased well attached to a wireline that is drawn upward by a continuously rotating wireline drum. The stick-slip motion results in the periodic upward movement of the tool in the cased well described in terms of a dwell time during which time the tool is stationary, the move time during which time the tool moves, and the stroke that is upward distance that the tool translates during the "slip" portion of the stick-slip motion. This method of measurement is used to log the well atmore »« less

Eddy current inspection tool which is selectively operable in a discontinuity detection mode and a discontinuity magnitude mode

Patent Petrini, Richard R. (Livermore, CA); Van Lue, Dorin F. (Livermore, CA)

A miniaturized inspection tool, for testing and inspection of metal objects in locations with difficult accessibility, which comprises eddy current sensing equipment (12) with a probe coil (11), and associated coaxial coil cable (13), coil energizing means (21), and circuit means (21, 12) responsive to impedance changes in the coil as effected by induced eddy currents in a test object to produce a data output signal proportional to such changes. The coil and cable are slideably received in the utility channel of the flexible insertion tube 17 of fiberoptic scope 10. The scope 10 is provided with light transmitting andmore »« less

Borehole logging method for fracture detection and evaluation

Patent Hornby, B.E.; Johnson, D.L

A method is describe for locating a fracture in a subsurface earth formation traversed by a borehole, the method using an acoustic source and at lest one acoustic detector traversing the borehole at a plurality of depths, the fracture positioned outside the direct path from the acoustic source to the at least acoustic detector, the method consists of the steps of: generating a first signal from the acoustic source, the first signal representative of Stoneley wave propagating in the borehole, receiving the first signal at the at least one detector, the first signal representative of Stoneley waves propagating in themore »« less
