Abstract

Bombay Offshore basin is the largest oil accumulation area in India. Oil was discovered in reservoirs varying from a few metres to about 100 m (328 ft) thickness in small and large pools scattered across the exclusive economic zone. Besides exploitation through a large number of conventional wells, as on date about 32 horizontal wells and 10 drain holes were completed and recompleted in the conventional wells respectively in major oil pools. L-II carbonate reservoir of Bombay High field, developed with a mix of horizontal and conventional wells, by far has the longest production history of horizontal wells. Horizontal well completion in this field under gas and water coning situations is considered as an excellent example of techno-economic success. However, much needs to be done in the areas of workover jobs, well testing and stimulation of these horizontal wells. There are several marginal pools discovered around major offshore fields having similar gas and water coning problems and/or low productivity. With rich experience gained through horizontal well technology, it is now possible to exploit the marginal fields with horizontal wells for improving oil recovery in Bombay offshore basin.
