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...

Development of Drilling Technology for Deep-seated Geothermal Resources

Concept of the deep-seated geothermal resources Deep-seated geothermal resources is defined as the depth of 3000-4000m at temperature of approximately 350 degrees C. And it is considered that those deep-seated geothermal resources exist below shallow geothermal reservoirs whch already exploited. 580,000 KW. And it is indispensable to explore geothermal resources " to increase it rapidly. In Jap...

Utilizing supercritical geothermal systems: a review of past ventures and ongoing research activities

Introduction High enthalpy geothermal systems have been harnessed for electrical power generation for over a 100 years. While the classification scheme for low, medium, and high enthalpy systems varies for different authors (Axelsson and Gunnlaugsson 2000; Benderitter and Cormy 1990; Hochstein 1990; Kaya et al. 2011; Muffler and Cataldi 1978; Nicholson 1993), reservoir temperatures above 150–22...
