Sentence examples for borehole televiewer from inspiring English sources
These structures can be detected by caliper or image logs or borehole televiewer tools.
The borehole image log, also called the BoreHole TeleViewer (BHTV) log, is very useful in evaluating the fracture geometry.
We have observed anthropogenic secondary minerals on borehole walls using a borehole televiewer (BTV) in boreholes drilled into granitic rock.
Three main joint sets were found from the logging of the rock cores, acoustic borehole televiewer, and window mapping.
The pressure time records obtained from the test intervals with pre-existing fractures are discussed according to the acoustic borehole televiewer (BHTV) images.
Advanced logging methods for fracture analysis and detection, like the borehole acoustic televiewer, Formation Microscanner (FMS), Formation MicroImager (FMI) and Electric MicroImaging (EMI) are more accurate, but they naturally require higher cost and can only produce images at specific certain intervals.
Fracture direction can also be determined by means of geophysical logs such as televiewer ultrasonic borehole (BHTV), formation micro imager (FMI), and Caliper Logs (Fig. 2).
We describe the capability and operation of BIFAT, and illustrate its application with reference to the automatic identification and annotation of sections from an optical televiewer (OPTV) borehole log from Roi Baudouin, Dronning Maud Land, Antarctica.
Since these view 360° around the full circumference of an exploratory borehole, intersecting planes are reconstructed on the televiewer image as sinusoids, the amplitude and phase of which can be used to calculate, respectively, the dip and direction of dip of each of these planes.
The practical significance of the proposed solution lies in the fact that it can be used as a quick-solver for back-analysis of borehole breakout images obtained in situ via a televiewer for the estimation of the orientation and magnitude of in situ stresses and of strain stress measurements in laboratory tests.
