The Mahogany Field in Trinidad and Tobago was discovered in 968 and 1974 with the EM-1 and EM-2 exploratory wells. In 1994, exploration resumed in the field with the drilling of 4 exploratory wells, EM-3, EM-4, EM-5, and EM-5XST, resulting in the discovery and delineation of significant gas, oil and condensate accumulations. Field development commenced in December 1997. The Mahogany Field is a faulted anticlinal structure with Pleistocene age stacked sand and shale sequences. There are 15 reservoirs in this field, with over 2TCF in gas reserves. The 21 sand is a major reservoir with a 63 ft to 75 ft oil leg, overlain by a large gas cap (430 ft at crestal position). Oil reserves at the end of 1998 were estimated at 27 MMSTBO (150 MMSTBO in place).
