WITH A FOCUSED EFFORT TO APPRAISE DISCOVERED RESOURCES AND TO ADD HYDROCARBON RESERVES IN BOTH ONSHORE AND OFFSHORE AREAS IN THE KINGDOM OF BAHRAIN, THE EXPLORATION DEPARTMENT EXECUTED A NUMBER OF TECHNICAL AND OPERATIONAL PROJECTS IN 2022.
 Initiated the first proppant fracturing pilot in Rubbles history – five (5) jobs have been completed and results are being evaluated.
Shallow Reservoirs
 Successfully increased the total production of Shallow reservoirs over the target with additional 1200 BOPD FYA, mainly from the extensive workover program, drilling and fracking campaigns.
 Completed fracturing forty-one (41) wells in OST/MAG reservoir peaked at 1,400 bopd with average production of 1,000 BOPD (as of December 2022). Total cumulative oil production produced from this project is 0.24 MMBO as of December 2022.
 Drilled Extreme Extended Reach wells in Ahmadi and the longest well in the Bahrain Field’s History (lateral section of 4,949 ft with 100% exposure in Ab-3 reservoir).
 Delineating Ahmadi reservoir in the east and south flanks with drilling long horizontal and deviated step out wells approaching and exceeding Oil-Water Contact (OWC) and still producing pure oil with initial rates of more than 100 BOPD.
 Expanding Gas Injection (six (6) injectors) in Ahmadi and (four (4) injectors) in OST/MAG reservoirs. The vicinity of mature injectors showed incremental oil gains and arresting decline, whilst showing an additional increase in reservoir pressure from 300 psi up to 700 psi in Ahmadi and 50 psi in OST/MAG.
 Successful implementation of Acid Fracture Campaign to OST/MAG and Ahmadi with total of one hundred eighty (180) wells.
 Started Tatweer Petroleum - ADNOC collaboration on Ahmadi project with focus on improving production, studying new technologies through trials and refine depletion plans. Shallow Reservoirs
Bahrain Reservoirs
 Continued Mauddud Tight Spacing Program by drilling twenty-five (25) infill producers in Mauddud Central Area in 2022.
 Reachedtotalproductionrecoveryof10MMBO from Mauddud Tight Spacing Program in 2022 with capital recovery exceeds 100%.
 Achieved the highest VRR in Tatweer Petroleum history, VRR reached 0.96 in 2022 FYA.
 Completed eight conversions to Gas Injection in Mauddud Central Area as part of Mauddud Tight Spacing Project – Phase 1 (AG Compression Phase 5 and 7).
 AchievedAGsupplytoBanagastargetof635 MMSCFD FYA and Field AG production target of 780 MMSCFD.
 Completedevaluationofsteampilotappraisal in Mauddud; suspended LOSF 7-Spot Pilot and completed all recommendations from close out report by December 2022.
 Established Phase 2 of Mauddud EOR Evaluation Study – Laboratory evaluation of EOR process with Freiberg University.
Deep Oil Reservoirs
 Drilled seven (7) Kharaib wells, including infill locations, whilst expanding away from the crest and targeting step-out locations.
 Deepened one (1) Kharaib well to Arab Reservoir for data acquisition and production evaluation.
 Completed routine core analysis for A-1003 (initiated in September 2020) and started special core analysis, expected to be completed by Q3 2023.
 Completed routine core analysis lab work for three (3) wells (A-2135D, A-2137D, A-2143D) in Arab-D formation and started special core analysis, expected to be completed by Q2 2023.
