Perform safe and efficient P&A of 22 platform wells and reduce P&A costs
Halliburton was awarded a multi-services contract from an independent oil company to provide plug and abandonment (P&A) services for 22 wells on five platforms located offshore Canada. The project operations started in December 2017, and were estimated to take approximately three years to complete.
The risks associated with conducting these multi-platform well P&A operations included:
These challenges had the potential to add significant cost to the project economics.
The Halliburton Project Management team was also tasked with leveraging its well abandonment expertise during planning and operational phases.
Given the sensitive nature of the worksite and the potential for incidents on an offshore installation, all possible exposures related to health, safety, and the environment (HSE) were treated with the expected due diligence, and this drove the implementation of scope-specific HSE key performance indicators (KPIs).
Halliburton was awarded a multi-services contract to provide services involving cementing, abandonment fluids, coiled tubing, slickline, e-line, tubing-conveyed perforating, and completions on a time and materials type of contract. This contract also included third-party nitrogen, milling, tubing handling, and fishing services.
Halliburton’s solution was in the development of a moonpool conversion of the rig with a skidding system to enhance overall operations permitting simultaneous operations of intervention and rig activities on two different wells at the same time.
Alignment was key between all project stakeholders, and common project delivery durations meant that all were accountable for performance and were mutually incentivized to collaborate to achieve. Similarly, alignment for HSE at the worksite drove a safety “one team” culture offshore.
A Halliburton team comprising a project manager, well intervention engineers, a performance development coordinator, and various Halliburton product service line (PSL) representatives were assigned to the project. The project manager was tasked with driving project efficiencies, and recommending and recommending Halliburton technologies and updated industry methodologies.
Successful implementation of the above included:
The Halliburton team captured lessons learned and opportunities for improvement, and leveraged experience from previous projects to help foster a safe work environment focused on continuous improvement.
Health, safety, and environmental (HSE) issues
Lost-time incidents (LTIs)
Days of SIMOPS
Wells on five platforms
The project was completed safely and efficiently – well ahead of the original planned schedule. It was delivered under budget and with zero HSE incidents or lost-time incidents (LTIs).
The alignment of all contractors, including Halliburton as the main contractor, and the efficiencies gained resulted in the project being delivered with 194 days of SIMOPS – ultimately reducing total project delivery time from three to two years.
The Halliburton team’s ability to work closely with the client to provide applicable solutions and to implement cost- and time-saving technologies were major contributing factors to the project’s overall success.
This successful project delivery has allowed Halliburton to gain the first integrated well abandonment project for offshore well work in Eastern Canada, while adding to our already robust P&A track record.
