A world-class development project
The Barda Rash PSC is 55 km north-west of Erbil, and holds the 14,015 mmbbls STOIIP and 1,433 mmbbls gross recoverable Barda Rash oil field. The field is defined as an elongated anticline with surface expression of 20 km length and up to 7 km width. The reservoirs are fractured carbonates of various depositional settings. In 2009, the BR-1 discovery well was drilled to 5,535 ft and successfully encountered oil in Cretaceous to Jurassic reservoirs. Well tests were carried out on the Jurassic Mus and Adaiyah formations, each yielding rates of around 3,200 bopd, with a subsequent extended test of the BR-1 well producing 440,000 barrels of 30° to 32° API oil over a three-month period. During this time, oil was trucked from onsite storage and sent to local refineries. Two further wells were drilled at the field in 2010, BR-2 and BR-3, both encountering oil full-to-base in all reservoirs. The field is defined by 326 km2 of good quality 3D seismic data. In 2012, we commenced the phased development of the field, initially targeting the development of light oil reserves. Having begun an extensive testing programme at the BR-1 well in July 2012, and establishing oil rates in excess of 6,000 bopd of 28° to 32° API oil, as well as obtaining valuable information on the production characteristics of the Mus/Adaiyah reservoir, we initiated production operations in August 2012. In July 2013, we commenced preliminary crude oil sales from the Barda Rash PSC to the local market. Gross production at the field averaged 639 bopd during 2013.
Afren has now moved to the second phase of development on the field, which involves drilling new wells to increase production capacity and acquiring modern log and core data to better understand and delineate the field. The Partners commenced drilling on the BR-5 well in Q1 2013 using the Romfor-23 drilling rig which is currently operating at circa 14,436 ft. They also commenced drilling the BR-4 well in May 2013, using the Viking I-10 rig. The well reached a total depth of 13,800 ft. As part of an ongoing programme BR-4 has tested two horizons in the Triassic Kurra Chine formation at 6,100 bopd and 1,750 bopd respectively. The BR-5 well has intersected a similar hydrocarbon-bearing sequence in the Kurra Chine formation and will be tested in due course. Flow lines and facilities will be updated to bring BR-4 and BR-5 into production during 2014.
On 8 August 2014, Afren announced that it had taken the precautionary step to temporarily suspend operations at the Barda Rash field in light of heightened regional security related issues. Working with our local security advisors, Afren isimplementing a phased withdrawal of non-essential field personnel from the Barda Rash field. All other Afren operations in the Kurdistan Region of Iraq remain unchanged. Afren will continue to closely monitor events on the ground in consultation with our security team and the relevant authorities. It is expected that Afren will return to field operations as soon as it is prudent to do so. The suspension is not expected to have a significant impact on the Group’s cashflow.
