Subsea market presents challenges
The subsea market is growing rapidly, but because of the expense of
subsea well intervention, fewer production logs are acquired. Reservoir
information is therefore insufficient for an accurate understanding of
reservoir connectivity, drainage, and flow assurance.
An additional constraint for wells requiring sand control is that
sandface sensors must be deployed on separate completion runs.
With the high cost of subsea well intervention curtailing the
acquisition of production logs, the industry needed a new permanent monitoring
system that included
- a robust mechanism to
deploy sensors
- a method for communicating real-time sandface data from the lower to the upper completion
- a multidiscipline interpretation strategy to maximize the value of those sensors.
