Low hanging fruit
While there is deeper exploration potential at the fields, he said the near-term goal is to go after producing zones.
Gross proven and probable reserves stand at almost 140 million barrels of oil, while total contingent resources are estimated to be about 110 million barrels.
About 631 million barrels has so far been recovered from an estimated oil in place resource base of 3.8 billion barrels, comprising 17 to 27 degrees API oil in Upper Cretaceous sands and much lighter crude in Lower Cretaceous reservoirs.
The seven producing fields — Kome (the biggest producer), Miandoum, Bolobo, Moundouli, Maikeri, Nya and Timbre — in which Savannah is acquiring a 75% stake were brought on stream between 2003 and 2009 and host some 300 wells in total.
In 2020, production averaged 33,700 barrels per day, but output is due to drop to about 30,000 bpd this year before Savannah’s well operations and infill drilling programme kicks in.
The new operator also aims to boost the performance of existing waterflooding and polymer flooding activities to enhance oil recovery.
A bonus for Savannah is that any fresh oil reserves it exploits can be fed into the Chad-Cameroon export pipeline, which runs for 1070 kilometres between the Doba basin and a floating storage and offloading vessel at Kribi port.
Savannah will control the pipeline and FSO with a 70% stake as part of the ExxonMobil-Petronas deal.
This pipeline’s capacity is 250,000 bpd, with throughput in 2020 averaging 129,000 bpd, about 75% of which came from other Chadian oilfields operated by China National Petroleum Corporation — which is producing about 100,000 bpd — and Taiwan’s OPIC, plus Switzerland-based Glencore, which is selling its assets to Perenco.
Knott said all three operators look set to increase production in the coming years.
The pipeline tariff is not related to oil prices, and in 2020 equated to about $3.6 per barrel for both ExxonMobil and Petronas and about $6.7 per barrel for the third-party shippers.
According to Savannah, total pipeline throughput is forecast to reach almost 160,000 bpd in 2027, with consultancy Wood Mackenzie estimating that output could potentially exceed 200,000 bpd by this time.
Savannah’s in-house broker finnCap noted that the upstream assets are expected to deliver net production of 22,500 bpd in 2022, with the pipeline forecast to transport 136,000 bpd.
Knott also pointed out there is the potential to to make more use of the Kribi FSO. "I think there's potential for us to allow third parties to link directly to our FSO and to evacuate crude."
On the ascent
FinnCap said the ExxonMobil-Petronas transaction is expected to boost Savannah’s total working interest production in 2022 by 144%, to 38,600 barrels of oil equivalent per day, and proven and probable reserves by 131%, to 183.1 million boe."
