WitrynaStrength determination for a stratum should be given using a number of individual determinations by specified means, i.e. triaxial, laboratory vane and hand vane tests (see BS EN 1997-2:2007, Annex M, P and I).. NOTE 3 The soil/rock boundary is set at an undrained shear strength of 300 kPa (an unconfined compressive strength of 0,6 … Witryna1 maj 1991 · Shear-wave Logging Using Multipole Sources. The Log Analyst 32 (03). Over the past decade, a new generation of acoustic logging tools has been developed. These new tools are specifically designed to measure formation shear velocity in all types of rocks-information that is not always available with a conventional acoustic tool. bars meridian

Azimuthally Focused LWD Sonic Logging for Shear Wave

WitrynaA feller buncher is a type of harvester used in logging.It is a motorized vehicle with an attachment that can rapidly gather and cut a tree before felling it. Feller is a traditional name for someone who cuts down trees, and bunching is the skidding and assembly of two or more trees. A feller buncher performs both of these harvesting functions and … Witrynacomponent and its parts. This comprises log or billet racks, the furnace, the hot shear or saw, the press, the run-out table, pullers, the cooling table, the stretcher, the batching table, feed conveyors, the saw table (with its own feed conveyors), the saw and the stacker. And, whereas a reliability of 99 percent might have been acceptable when Witryna25 cze 2015 · Whenever possible, amplitude data should be used in conjunction with the other measurements presented on the log (e.g., travel time or full waveform) for a more-reliable bond evaluation. For example, the presence of shear-wave amplitudes on the full-waveform display is an indication of good acoustic coupling to the formation. su 管理员
