Multi-PSL team executes deepwater subsea P&A projectDownload PDF
Collaborate to perform operator's first local deepwater subsea P&A project
Halliburton was awarded a multi-services contract to provide plug and abandonment (P&A) services offshore Malaysia for two subsea wells. The P&A project was conducted from the operator’s semi-submersible rig, and Halliburton provided all services related to the project.
The complexity and risks associated with conducting well abandonment operations for deepwater subsea wells is significantly higher compared to platform P&A work scopes, and includes:
These challenges had the potential to add significant cost to the project’s economics.
Halliburton Project Management (HPM) was tasked with integrating multi-services teams from various Halliburton product service lines (PSLs) and third-party contractors to leverage well abandonment expertise during planning and operational phases. HPM consolidated plans, and evaluated all the risks that the project posed, specifically relating to execution.
Given the sensitive nature of the worksite and the potential for incidents on an offshore installation, possible exposures to risks related to health, safety, or the environment (HSE) were treated with the expected due diligence, driving the implementation of scope-specific HSE key performance indicators (KPIs).
Halliburton was awarded an integrated services contract that included wireline and perforating services (e-line and slickline), coiled tubing, completions, tubing retrieval, high-expansion retrievable bridge plugs (through third-party services), tubular running services, and fishing and milling services.
The HPM team worked with the customer to finalize the program’s work scope, schedules, KPIs, and drivers for project efficiencies, and to implement Halliburton technologies. Successful implementation of the above include the following:
days to complete mobilization
HSE or LTI incidents
Remote operation of Downhole Electric Pipe Cutter tool
NPT or service quality events
Through close collaboration with the customer, Halliburton was able to mobilize within 90 days and achieve the following results:
