Results of Large-dlqmeter Well Drilling in Philippine Geothermal Felds
4 large hameter casing design was adopted for 34 vells drilled in the Philippines using 13-3/8” mduction casing in combination with 9-5/8’ slotted iner to improve well output and to reduce space equirement in collaring the wells. Well test results ndicate an increase in production by as much as !50% compared with wells using the usual string ambination of 9-5/8” and 7-518”. In the 600 MWe q t e...
متن کاملA Comparison of Geothermal with Oil and Gas Well Drilling Costs
The costs associated with drilling and completing wells are a major factor in determining the economic feasibility of producing energy from geothermal resources. In EGS power plants, estimates place drilling costs as accounting for 42%-95% of total power plant costs (Tester et al., 1994) depending on the quality of the EGS reservoir. An earlier correlation first developed by Milora and Tester (...
متن کاملmonitoring of khiav river water during exploration well drilling at sabalan geothermal field, northwestern iran
in this paper, the results of surface and ground water quality monitoring during drilling of three deep exploratory wells in geothermal project in north west of sabalan in meshkinshahr are analyzed. the region has been investigated by various researchers to generate electricity using geothermal energy. drilling in deep geothermal projects, a variety of materials such as cement, bentonite, barit...
متن کاملAdoptive Control of Well Drilling Systems
Control of well drilling operations poses a challenging issue to be tackled. The loss of well control could lead to the occurrence of blowout as a severe threat, involving the risk of human lives and environmental and economic consequences. Conventional proportional-integral (PI) controller is a common practice in the well control operation. The small existing margin between pore pressure and f...
متن کاملEquivalent Circulation Density Analysis of Geothermal Well by Coupling Temperature
The accurate control of the wellbore pressure not only prevents lost circulation/blowout and fracturing formation by managing the density of the drilling fluid, but also improves productivity by mitigating reservoir damage. Calculating the geothermal pressure of a geothermal well by constant parameters would easily bring big errors, as the changes of physical, rheological and thermal properties...
