FAR's Gambia Well Finds Oil Traces. Side-track Required after 'Significant Fluid Losses'

FAR, an Australian oil and gas company that began drilling at the Bambo-1 exploratory well in Block A2 off the coast of The Gambia last month, said Monday the well had encountered oil traces but would have to be plugged and side-tracked after drilling was temporarily halted due to significant fluid losses.

"FAR advises that the Bambo-1 well has drilled 3216m MDBRT (measured depth below the rotary table) of a total planned depth of 3450m MDBRT. Oil indications have been detected in rock cuttings and hydrocarbons have been interpreted across several intervals in the well from LWD data (logging whilst drilling). Further wireline logging needs to be completed to confirm the finding," the company said.

"Drilling operations were temporarily halted at the current depth after significant fluid losses were experienced. These fluid losses were stabilized in accordance with standard offshore operating procedures, and FAR is now planning to plug and side-track the well to continue drilling to the planned total depth," it added.

"Prior to side-tracking and provided hole conditions remain stable, FAR is undertaking a wireline logging program in the current well bore. FAR estimates that the cost to complete the well will increase from a total of US$51.4M to US$61.27M, an increase of US$9.87M or US$4.935M net to FAR," FAR, which is using the Stena IceMax drillship for Bambo-1 drilling. The Bambo-1 well sits around 85km offshore The Gambia, in 930 meters of water depth.

FAR forecasts a cash balance of US$37M after the completion of the well, inclusive of the increase in Bambo-1 well costs. The addition of the side-track program has extended the period of operations which is now expected to be completed by the end of December 2021, the company said-

The well has been designated a “tight hole” by FAR and JV partner Petronas and as such, no information related to depth or formation is likely to be provided during the drilling beyond what is required to meet ASX continuous disclosure obligations, the ASX-listed firm said.

"Market participants should exercise care before transacting in FAR shares until such time as FAR, as Operator of the Joint Venture, makes formal ASX disclosures regarding well results," FAR said.

FAR’s Managing Director, Cath Norman, said “FAR is pleased with the experienced drilling team and contractors who have acted to quickly manage and adjust the Bambo-1 drilling program to suit the geological setting and best meet the objectives of the drilling program. FAR is well placed to achieve these objectives through the side-tracked well and in particular drilling through the as yet undrilled Soloo Deep prospect. We are encouraged by the presence of oil in potential reservoirs and look forward to completing the well in the coming weeks.”

The Bambo well has been designed to drill into a series of vertically stacked targets with a combined estimated recoverable, prospective resource of 1,118 mmbbls (arithmetic sum of the Best Estimates, un-risked, 559 mmbbls net to FAR) and, before the drilling started, FAR calculated the chance of geological success for the various horizons to range from 7% to 36%.

FAR is the operator of the offshore block with a 50% working interest in the A2 and A5 permits with its joint venture partner, PC Gambia Ltd, a subsidiary of Malaysia's Petronas, holding the remaining 50%.

FAR has previously said that, if successful, a discovery could result in a standalone development which would be The Gambia’s first oil production.
