... Abstract Sapura Energy (Drilling Contractor) has developed a lightweight drilling package for a long-term plug and abandonment (P&A) campaign, designed to deal with wellbore uncertainties while remaining light enough to be rigged up on aging platforms. The package was deployed...

... technology available and adopting it to reduce operating time, project risk and ultimately cost. The final phase of the plugging and abandonment (P&A) is the well severance and conductor removal operation that is traditionally performed using mechanical knives for rig-based campaigns. This involves...

... to the conventional rig based decommissioning. However, with the day rates of Jack-up rigs slashed down to 35-40% of that of the pre-downturn period, entails us to revisit the strategy regarding the selection of the method for decommissioning. Therefore, this paper presents a framework that encompasses various...

... Abstract Conduct comparative evaluations of offshore wells abandonment projects on either platform or underwater, whether rig or rigless. Identify challenges and effectiveness in terms of operations and costs. Discuss the preparations to be made before the work and the procedures to be done...
