Thermal Response Test While Drilling
Knowledge of the ground thermal conductivity is of importance when designing borehole heat exchanger (BHE) systems. As thermal conductivity for any specific rock type varies due to its mineral content, porosity, pore fluid and anisotropy, it is preferable determined in-situ. Choudhary (1976) suggested a method for determining the thermal conductivity which analysed the heat transfer during the ...
متن کاملHorizontal Directional Drilling-Length Detection Technology While Drilling Based on Bi-Electro-Magnetic Sensing
The drilling length is an important parameter in the process of horizontal directional drilling (HDD) exploration and recovery, but there has been a lack of accurate, automatically obtained statistics regarding this parameter. Herein, a technique for real-time HDD length detection and a management system based on the electromagnetic detection method with a microprocessor and two magnetoresistiv...
متن کاملIndependent drilling outperforms conventional transtibial drilling in anterior cruciate ligament reconstruction.
BACKGROUND Optimal tunnel placement is critical in anterior cruciate ligament reconstructive surgery, yet the method used to drill the tunnels may compromise their placement. HYPOTHESIS An independent drilling method versus a conventional transtibial drilling method will place tunnels in different locations and produce reconstructions with different kinematics. STUDY DESIGN Controlled labor...
متن کاملRealtime sensing while drilling using the USDC and integrated sensors
The search for existing or past life in the Universe is one of the most important objectives of NASA’s mission. In support of this objective, an ultrasonic based mechanism is being developed to allow probing and sampling of rocks and soil. The novel lightweight Ultrasonic/Sonic Driller/Corer (USDC) used in this study takes advantage of its ability to drill with low axial force and low power. Th...
متن کاملAn Experimental Study Of Seismoelectric Signals In Logging While Drilling
Acoustic logging while drilling (LWD) may be complicated because of contamination by waves propagating along the drill collar (the tool waves). In this paper we propose a new method for separating tool waves from the true formation acoustic arrivals in borehole acoustic LWD. The method utilizes the seismoelectric signal induced by the acoustic wave at the fluid-formation boundary. The basis for...
