Subsea SPIDR Applications

[RodK]

We've recently been contacted by a Gulf of Mexico operator who is performing removal operations of platforms toppled by last years hurricanes, to monitor the casing pressure (at mudline) of shelf well(s) during Abandonment operations.

Because of our long-standing arrangement with Oceaneering where we supply SPIDR gauges to them for deepwater deployment, this is a fairly benign application for the SPIDR.
Oceaneering is able to supply and install the SPIDR and cabling back to the barge to monitor pressures, real-time, for extended periods. i.e. 30 days or longer as required.

We started working with Oceaneering about 5 years ago when an operator in the Gulf of Mexico who operated Subsea wells, experienced failure of his Downhole Permanent Pressure Gauge (DHP) and was concerned with producing the well at too high a drawdown and damaging the completion. The SPIDR / Oceaneering solution was pioneered, designed and utilzed to gather pressure data at the Subsea Wellhead for use in Pressure Transient Analysis.

This is an excellent application for a couple of reasons.

1) It can be used to establish a relationship between pressures with the DHP and the SPIDR while the DHP is still functioning as a backup in case the DHP fails at some future point.

2) As a stand alone pressure data gatherer when the DHP has already failed. DRC's core business is acquiring pressure and accurately converting that pressure to BHP via our proprietary algorithm

3) The system can be utilized by Oceaneering or rented out to other ROV operators who may have occasional Subsea work to perform where gathering pressure alone would not support the cost of the entire operation.
