The total reconciled oil and associated gas produced for H1 2024 were 16,405,020.00 bbl and 42,581.32 MMSCF at average rates of 90,137.47 bbl/d and 233.96 MMSCF/d, respectively, according to the Public Interest and Accountability Committee(PIAC).
In the 2024 PIAC Semi-Annual report, it notes that the highest cumulative monthly oil produced within the reporting period was recorded in March 2024, as a result of the ramping up of J03-P and J69-P (post-commissioning of J69-P in late February).
A total volume of 3,056,353.00 bbls was produced at an average of 98,592.03 bbl/d. June recorded the least cumulative oil production, producing a total volume of 2,570,305.00 bbl at an average rate of 85,676.83 bbl/d.
The low production obtained in June 2024 was mainly attributed to facility upsets. Production was slightly cut back to manage high flaring as a result of the low-pressure gas compressor (LPGC-A) trip and Ghana National Gas Limited Company (GNGLC) processing plant trip. The TEG contactor also tripped due to a faulty level transmitter.
The report explained this then had a cascading effect which tripped all the gas compression systems resulting in the choking down of some wells to minimise flaring rates.
The gas export profile followed a similar trend as oil production, but significant decrease in gas export from April 2024, which recorded the lowest export rate, was mainly due to process upsets at the Ghana National Gas Limited Company (GNGLC) plant
Seventeen (17) crude off-take operations were carried out from the Jubilee field. A total volume of 16,183,076.00 net1 bbls of oil was lifted by the Jubilee partners in H1 2024.
Together with Petro SA Ghana Limited, Tullow Ghana Limited (TGL) made seven (7) liftings (6,640,375.00 bbls),representing 41.03 percent of the total volume of Jubilee
liftings; Kosmos Energy made six (6) liftings (5,728,856.00 bbls) representing 35.40 percent; Further, the report highlights that GNPC Exploration & Production Company Ltd. made one (1) lifting (951,903.00)representing 5.88 percent.
The Ghana Group made four (3) liftings (2,861,942.00 bbls) representing 17.68 percent.
The TEN Field, like the Jubilee Field, is an associated gas field with similar production trends in both crude oil and gas.
The total reconciled oil and associated gas produced H1 2024 were 3,450,445.00 bbls (see Table 4) and 28,701.05 MMSCF at average rates of 18,958.49 bbls/d and 157.70 MMSCF/d respectively. The highest cumulative monthly oil produced within the reporting period was recorded in March 2024. A total volume of 600,859.00 bbls was produced at an average rate of 19,382.55 bbls/d. February recorded the least cumulative oil production, producing a total volume of 530,542.00 bbls at an average rate of 18,294.55 bbls/d (see Figure 2). The low production in February was largely attributed to flow assurance issues, and the nonperformance of oil-producing wells: En08-P and En10-P.
In the reporting period, approximately 85.78 percent (24,618.66 MMSCF) of the cumulative produced gas of 28.70 bcf from the TEN field was reinjected into the Ntomme field for pressure support whiles 2.78 bcf representing 7.58 (2,176.76 MMSCF) percent of the total gas was flared. Out of the remaining total gas produced, about 104.43 MMSCF, representing 0.36 percent of the produced gas was exported to GNGLC at an average rate of 0.57 MMSCF/d, while 1,801.22 MMSCF representing 6.28 percent of the produced gas was used as fuel.
Typically, the TEN gas is exported to substitute for Jubilee gas due to technical constraints when Jubilee is unable to meet nomination by GNGLC.
Three (3) crude off-take operations (liftings), amounting to 2,982,272.00 bbls, were made in the TEN Field in H1 2024 as follows: Together with Petro SA Ghana Limited, Tullow Ghana Limited (TGL) lifted twice(1,987,699.00 bbls) representing 66.65 percent of the total volume of TEN liftings; and, Kosmos Energy Ghana HC lifted once (994,573.00 bbls), representing 33.35 percent. of the total volume of TEN liftings.
Neither the Ghana Group nor GNPC Exploro 3 made a lifting in TEN in H1 2024.
