Abstract
Nowadays oil and gas industry are encouraging the independents and majors to take a fresh look at the technology and concepts required to develop marginal shallow water fields using a minimal platform approach. Innovation on well intervention means (lighter, smaller and less footprint) that fit for Offshore Minimalist Platform (OMP) is needed, including optimizing time and cost during well intervention activities in OMP.
To achieve the objectives, well intervention innovation and technology are the main focuses. Intervention activities commonly done on campaign basis with several units (slickline, wireline, coiled tubing, testing) shall be integrated in a safe manner. The approach of integration shall signify these points:
Identifying potential jobs in OMP to be done by well intervention methods
Identifying necessary well intervention means and methods to support the jobs (combo unit, micro coil, hazardous zone redefinition, remote operation)
Creating project planning and scheduling
Performing site visit and risk assessment
Implementation and operational execution
Evaluation of overall project execution result
The following results were obtained after the integration performed:
No major safety issues during operation
Exemplary method and risk assessment for well intervention activities which can be applied for next campaigns
Trials on well intervention new units and method (combo unit, micro coil, hazardous zone redefinition, remote operation), were safely performed with some optimization
100% success ratio
60% on supply boat arrangement
35% efficiency in N2 consumption for CT operation
45% efficiency in diesel consumption
20% - 40% efficiency in Rig Up Time
28% less in Job Cost compared to conventional unit
These innovations are proven as reliable method to answer OMP challenges with main advantages on footprint and cost optimization. Through this paper, we would like to share lucrative well intervention breakthrough and innovation in OMP with measurable milestones.
