As geoscientists working the Offshore Gulf of Mexico we are often asked, “why can’t you find normally pressured, shallow water prospects near shore?”Main Pass 61/62 Field (MP 61/62) is one of those management dreams come true. This field is located in 90 feet of water, 9 miles off the Mississippi river delta and situated among three fields that have produced 1/3 of the Federal Main Pass OCS portraction area oil and gas. MP 61/62 is a normally pressured, stratagraphic trap located at a depth of 7,200 feet sub-sea true vertical depth (SSTVD). Working off nearby company properties, and utilizing traditional subsurface and 3D seismic control, discovery and development of 50 million barrels of oil equivalent took 30 months. The field’s production of 20–30,000 barrels of oil equivalent per day was accomplished by the installation of two manned platforms and two caissons. A third water injection platform was installed to maintain a formation pressure in the primary reservoir.
