Abstract

Abstract The geology of offshore oil and gas fields varies widely, but imposes constraints and opportunities for developing offshore hydrocarbons. This becomes evident during the E&P Life Cycle (Find‐Develop‐Produce) as the field geology influences locating and testing exploration prospects with seismic and wildcat drilling, optimizing the number and location of development wells and production facilities, and the field's production rates and ultimate recovery. To reduce geologic uncertainty, a stepwise approach to acquiring information is usually employed, as shown by two examples. The Tahoe Field in the Deepwater Gulf of Mexico and the Lula Field in the Brazil Offshore Subsalt both utilized a similar approach to offshore development, which allowed for increasing understanding of the field geology while reducing uncertainty.
