A customer needed to re-evaluate a
previously abandoned well in deepwater
Gulf of Mexico. The slot had been abandoned
at the 20-in. casing shoe due to an extremely
narrow pore pressure fracture gradient
window and the associated risks of
weakening the integrity of adjacent wells.
The area had a history of shallow hazards
and shallow water flow conditions, causing
significant problems in the past. To examine
the feasibility of recovering the slot required
undertaking a formation integrity test. The
time and cost of purchasing a riser, installing
a blowout preventer (BOP), and the relevant
rig time made this choice uneconomical
with conventional technology and current
economic conditions. xact-facilitated-riser-less-test-gom-cs.pdf
