Integrated Drilling and Production System
IDPS Business Case
Developing subsea infrastructure that significantly reduces need for costly rig, and moves activities onshore
Suitable for majority of the global subsea oil and gas developments. Unique competitive advantage on single well tie-backs and large field developments
The IDPS will improve field development economics due to a number of efficiencies and cost reduction factors from life of field applications.
Contact NST to conduct a detailed business case for your application. NST may assist you with identifying the most cost effective solution for your field development.
Moving well construction onshore
The IDPS is fully assembled and tested onshore and is installed as a single unit prior to drilling the well.
Schedule flexibility
No further subsea production system installation activities are required after initial installation. The production facility can be hooked up even before completing the well activities if required.
Life of Field
The IDPS brings significant improvement in flexibility, allowing for quick and cost effective recovery and repair when required.
Logistics
The IDPS well design will result in reduction in pipe handling, base activity, and vessel movements, lowering logistics cost
Installation and removal
The IDPS will be installed and removed by using a vessel only, no rig will be required to establish the well foundation. The IDPS will facilitate a robust slim design with efficient P&A activities. The IDPS slim well design may include the 13 3/8” seamless casing in first hanger position, which allows for high differential pressure, liners over casings, efficient well construction, well testing and P&A activities
Vessel vs Rig
The IDPS well design moves activity from rig to vessel, significantly lowering the cost per day for installation activities
Rig type
The IDPS will improve economics of selecting a single activity rig over a expensive dual activity rig. The open water activities are significantly reduced with the pre-installed well foundation. Well economics may improve further for moored rigs in combination with the IDPS design, due to potential synergies of combining IDPS installation with pre-laid mooring.
Water depth
IDPS well design economics improve with increased water depth, as the open water activities such as tripping become more critical for overall well construction efficiency
