A Numerical Simulation Study on Wellbore Temperature Field of Water Injection in Highly Deviated Wells
According to the temperature distribution of water injection well-bore in highly deviated wells under different conditions and unstable temperature field heat conduction principles, a true three-dimensional model was established to analyze the law of variation on temperature of highly deviated wells during the water injection process, and to analyze the factors that influence the water injectio...
متن کاملBorehole Geomechanics in Petroleum Exploration and Development: From Controlling Wellbore Stability to Predicting Fault Seal Integrity
Few in the Australian oil patch were familiar with the term 'borehole breakout' when David Lowry alerted PESA Journal readers to this phenomenon (1990, v.17, p. 43-44). Ten years later, few are unfamiliar, with breakouts having been reported in every Australian basin subject to significant drilling activity. This change witnesses the dramatically increased awareness of borehole geomechanics in ...

متن کاملSIMULATION OF WELLBORE COOLING BY CIRCULATION AND INJECTION Leonard
The high temperatures existing within a geothermal well preclude the use of most logging instrumentation which is necessary to study the wellbore and surrounding rock matrix. Possible solutions to this problem include cooling the wellbore and the surrounding rock by circulating fluid in the wellbore and by injecting fluid directly into the rock matrix. The latter method, however, is not preferr...
متن کاملGeothermal energy from abandoned oil and gas wells using water in combination with a closed wellbore
Binary cycle power plants have been used successfully for electricity generation utilizing co-produced fluids from active onshore oil wells. Adapting this process for use on abandoned wells by circulating the binary working fluid down the wellbore has been previously proposed and a selection of fluids evaluated. This work proposes and evaluates an approach using water as the wellbore fluid in c...
