Ithaca Uses ROV Support Vessel for Intervention on Athena Field (UK)

Ithaca Uses ROV Support Vessel for Intervention on Athena Field (UK)

Ithaca Energy Inc. announces an Athena field operational and production update.

The planned hydraulic intervention to eliminate the production tubing blockage in the P1 well, using a Remotely Operated Vehicle Support Vessel, has been performed. This intervention, involving the pumping of fluids into the P1 well flowline (at the wellhead), has resulted in a minor incremental increase in the previously observed flow rates achieved from the well, with gross production from the well now being approximately 700 to 800 barrels of oil per day (“bopd”) (160 – 180 bopd net to Ithaca).

The production data that has so far been obtained from the field indicates that the anticipated sweep of oil within the reservoir is likely to result in the reserves attributed to P1 being fully produced by the well in its current production condition, supported by recovery from the other wells on the field. The P1 well is the original appraisal well that was drilled on the field in 2006 (completed as a development well in 2011) and represents the least significant producer in terms of forecast ultimate oil recovery from the field.

Based on the results of the P1 hydraulic interventions and an assessment of reservoir performance, the Athena co-venturers have decided that the value of producing the P1 well in its current condition outweighs the benefit of performing a workover on the well using a drilling rig. The well will therefore now be produced in its current condition. Future attempts to further clear the blockage by applying hydraulic pressure, using the facilities on the FPSO, may be undertaken when operations allow.

The field continues to produce dry oil and the field facilities are performing well.

Ithaca third quarter production figures will be announced as usual in early October and a further update on Athena performance will be included at that time.

The co-venturers in the Athena field are: Ithaca, operator (22.5%), Dyas UK Limited (47.5%), EWE Energie AG (20%) and Zeus Petroleum Limited (10%).

Substructures for UK Offshore Wind

Design, construction and installation

Optimising offshore substructures is one of the key challenges for reducing LCOE. Foundation designers have produced a variety of different solutions: monopiles, GBS, jackets, suction buckets and floating foundations. Looking at U.K. projects – different soils, water depths,fabrication timelines and installation challengescreate many questions for the industry to solve. We’re entering uncharted territory; projects arelarger, farther and more complex than ever completed.

Now is the time to have a close look at lessons learnt and define the room for improvement for the U.K. wind industry.
