AGR to deliver reservoir modelling support on Draugen field

AGR has announced it will be assisting Norwegian operator OKEA by building a new full field reservoir model for the Draugen asset in the Norwegian Sea.

Draugen was discovered in 1984 and the oil is found in the Garn and Rogn formations, of which the latter holds approximately 90% of the reserves. The western part of the field also produces from the sandstone of Middle Jurassic age in the Garn Formation.

It has been producing since 1993. OKEA ASA is the operator with 44.56% interest, with Petoro (47.9%) and Neptune Energy (7.56%) as partners in the license.

The field has been developed with a concrete fixed facility and integrated topside and has both platform and subsea wells. Stabilized oil is stored in tanks at the base of the facility. Two pipelines connect the facility to a floating loading-buoy.

According to OKEA, the current production on Draugen is in the order of 23,000 bbl of oil and nearly 180 000 bbl of water per day. 110 000 bbls of water are reinjected to the reservoir, while the rest is discharged to the sea with an oil in water of approximately 20 ppm.

“We are excited to deliver this project as part of our long-term relationship with OKEA. We’ll be applying our in-house expertise to build the model, from its elements up to a history-matched dynamic model, which will be used for forecasting the assets’ production volumes for many years to come”, André Sæthern, AGR’s VP of Reservoir Management, said.

“AGR is a highly competent reservoir consultancy that has consistently demonstrated its ability to deliver similar large-scale projects. We’re pleased to partner with them on this latest development and look forward to working together to provide a first-class reservoir model for the Draugen asset”, Håvard Morset, Draugen Subsurface Manager at OKEA, comments.

The AGR project team will cover skills of Geophysicists, Petrophysicist, Sedimentologist, Geomodellers, Reservoir Engineers and a Production engineer.
