Gaz du Cameroun announces spudding of two development wells in Logbaba Gas Field, Cameroon


Victoria Oil & Gas’s Cameroon gas producing and distributing subsidiary Gaz du Cameroun has announced the spudding of development wells La-107 and La-108 in the Logbaba Gas Field located in Douala, Cameroon. 

The wells are being drilled by Savannah Oil Services Cameroon using the Komako 1 drilling rig.

The new wells will have to meet the expanding market demand for gas in Douala in order to develop Logbaba reserves and move some of the 2P (proven plus probable) reserves into the 1P (proven) reserve category.

La-107 will twin the La-104 well drilled in 1957, while La-108 will be a ‘step-out’ well that will be drilled into a target intended to prove up more probable reserves.

"La-107 will twin the La-104 well drilled in 1957, while La-108 will be a ‘step-out’ well that will be drilled into a target intended to prove up more probable reserves."

Both wells will be drilled directionally from a drilling pad close to the Logbaba processing plant, and will be linked into this facility once completed. 

The La-104 twin well is almost vertical, while La-108, the ‘step-out’ well, will be drilled to intersect a target that is approximately 1,100m south-east of the Logbaba drilling pad.

The wells are meant to be production wells completed in the Upper Cretaceous (Campanian and Santonian) Logbaba Formation, a thick sequence of interbedded sands and shales found at depths between 1,700m and 3,200m below the surface. 

As well as developing the gas reserves in the Logbaba Formation, one of the wells, La-107, has an additional objective of an ‘exploration tail.’ This is to be drilled from the base of the Logbaba Formation down to 4,200m below the surface to test the hydrocarbon potential of the Lower Cretaceous Mundeck Formation, which had gas shows and a significant gas kick in La-104 (twinned by La-107).

Implementation of the exploration tail is dependent on well conditions to be established during the drilling programme.

Without the exploration tail, the budget total for the two well programme is approximately $40m, which is expected to be funded by revenue and partner contributions.

Owned and operated by Savannah, the Komako 1 drilling rig is a 1500HP rig mounted on rails. The rail system enables the rig to be moved back and forth between the two wells as they are ‘batch drilled’.

The rig has been assembled, tested, commissioned and has also passed an independent third party rig inspection audit prior to spud. 

Drilling is slated to complete in the second quarter of 2017.
