This is typically done through the use of cemented liners or casings, along with additional cement or mechanical plugs that provide multiple barriers to hydrocarbon flow.The narrow margins between pore pressure and fracture gradient established a challenging environment for sealing the well.
Operator training for emergency BOP operation should be improved to the point that the full capabilities of a more reliable BOP can be competently and correctly employed when needed in the future.
