Abu Sennan concession (Rockhopper 22%)
Production from the six development leases within the Abu Sennan concession increased during 2018 with production during the period averaging approximately 813 boepd net to Rockhopper (2017: 760 boepd).
In July 2018, Rockhopper was pleased to announce the commencement of the 2018 drilling campaign on the Abu Sennan concession which included the drilling of two development wells (“Al Jahraa-6” and “Al Jahraa-10”), one exploration well (“ASZ-1X”), and a water injection programme targeting the Al Jahraa field.
The Al Jahraa-6 development well spudded on 4 July 2018 and reached total depth of 3,935m MD (-3,623m tvdss) in the Kharita Formation on 19 August 2018. Mudlogs indicated the presence of oil in the Abu Roash C, D, E and G levels and the deeper exploration target in the Bahariya Formation. The Bahariya formation was put on test on 22 September 2018 and, after clean-up, is producing in excess of 550 barrels of oil per day (“bopd”) with a stable water cut of 22%. This represents the first commercial oil production from the Bahariya formation within the Abu Sennan concession. The well has been completed to allow potential future production from Abu Roash G and C levels. The Company believes that the Bahariya discovery de-risks additional exploration targets at the same level elsewhere in the concession.
The Al Jahraa-10 development well reached total depth on 16 October 2018 in the Abu Roash-F Formation. Oil pay was calculated in the Abu Roash-C and Abu Roash-D levels. Following testing operations, the well was brought into production from Abu Roash-C at a rate of 130 bopd gross, and subject to further increase. Upside potential exists in Abu Roash-D which is being evaluated for possible acid stimulation.
Exploration well ASZ-1X located on Prospect S was spudded on 8 November 2018 and was the first of two commitment wells to be drilled in the first phase of the new concession. An oil discovery was made in the Abu Roash-C level. The award of a development lease over the discovery has recently been approved by EGPC and production has commenced.
The water injection programme in Al Jahraa began on 14 July 2018. Injection rates have increased steadily over time, with an accompanying reduction in wellhead pressure, indicating that reservoir injectivity has become established. Injection rates into the Al Jahraa-9 well are currently averaging approximately 2,000 barrels of water per day, which is sufficient to re-pressurise the reservoir.
2019 drilling campaign
Following joint venture approval, an active drilling programme has been agreed for 2019 including the drilling of one exploration well (SW-ASH-1X), two in-fill oil producer wells (Al Jahraa-11 and Al Jahraa-7) and a second water injection well on the Al Jahraa field. Activity in 2019 continues the planned development programme in the Al Jahraa field, as well as further exploration on the concession.
The Al Jahraa-11 development well, the first in the 2019 programme, was spudded on 13 March 2019 and is targeting the AR-C and Bahariya reservoirs. The well is expected to take approximately two months to complete.
