Cased Borehole Effect on Downhole Seismic Measurements
Approximate and exact formulations are presented for the interaction of an incident wave with a cased borehole. In the approximate method, the borehole coupling theory is used to compute pressure in the fluid at a low frequency. The results are simple and explicit. They are useful in the study of cased borehole coupling and as well as borehole radiation. In the exact method, elastic potentials ...

Results of Laboratory Experiments to Simulate the Downhole Environment of Formation Testing While Drilling
A laboratory-based experimental study was conducted to more completely understand the fundamentals of pressure transients produced by Formation Testing While Drilling (FTWD) equipment. These tools can be run in open hole, positioned at a desired level, and actuated to measure reservoir pressure and flow capacity while in a dynamic drilling environment. Any number of pressure measurements can be...
متن کاملHeave compensation and formation strength evaluation from downhole acceleration measurements while coring
In order to evaluate the efficiency of heave compensation in the Ocean Drilling Program, we developed a device measuring the acceleration of the core barrels. First results show that heave compensation limits bit motion to 10% of the surface heave. We also use the acceleration data to characterize the formation. On rotary corers, acceleration amplitudes decrease with increasing hardness of the ...
متن کاملThermal 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 ...
