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 کاملDevelopment 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...
متن کاملDrilling for Polygons
We solve the problem of designing a simple device that uses rotary motion to drill a hole with a cross-section that is a regular polygon with an odd number of sides: the main idea is to use a polygonal trammel and a family of rotors. By using different rotors, one can produce a hole with a cross-section that is in any proportion of the trammel size from zero to exactly one. The key geometric id...
متن کاملDrilling for microbes.
For scientists who study subseafloor sediment, it’s not unusual to spend a lot of time at sea aboard a ship with a gaping hole in its hull. Known as a moon pool, the hole serves as a portal for the ship’s weighty drilling equipment to retrieve core samples of seafloor sediment thousands of meters below. Aboard scientific research vessels, such as the JOIDES Resolution, University of Rhode Islan...
متن کاملAn Optimization Algorithm for the Layout of Well Drilling
The author designs a genetic algorithm for the layout of well drilling based on partial order relations and establishes a mathematical model for the algorithm. Based on this, ideal results are obtained. The results of numerical experiments show that the algorithm is highly precise and runs at a rapid speed.
