When operators abandon a well, they are obliged to leave it in a condition that protects both the downhole and surface environment in perpetuity. This involves removing completion hardware, setting plugs, and squeezing cement into casing annuli across producing and water bearing zones to act as permanent barriers to pressure from above and below.
Minimising the cost of these operations, without sacrificing the integrity of the abandoned well, is critical to operators who must make these significant investments that carry no financial return. In the event a seal fails and well fluids leak to surface, or cross flow into another formation, the operator is liable for fixing the problem.
Ikon Science can reduce the size or number of cement plugs and still assure long-term isolation integrity. In fact, our goal is to enable operators to reduce plugging and abandonment costs by up to 35%.
Ikon Science's decommissioning proposal
- Study regional and local pore pressure and geomechanical stresses using static and dynamic reservoir data
- Build a basin-scale, integrated geopressure and geomechanical model of the linked aquifers and pressure systems affected by oil and gas extraction and water injection over tens of years
- Perform robust well-by-well risk assessments of seal breach, leaking faults, and cement plug failure
- Optimise and simplify well abandonment while minimising the risk of hydrocarbon leakage to surface or between formations
