Buffalo-10 Well Drilling Update

Advance Energy ( AIM:ADV ), the energy company seeking growth through acquisition or farm-in to non-operated interests in discovered upstream projects, is pleased to provide an update on the Buffalo-10 well being drilled offshore Timor-Leste.

The Operator, Carnarvon Petroleum Timor, Lda., has advised that since the last announcement on 31 December 2021, the conductor has been installed and cemented in place, and the 17 1/2 " hole has been drilled down to planned section total depth of approximately 804 metres measured depth ("MD").

The rig is now setting and cementing the 13 (3) /(8) " casing and installing the wellhead, before drilling ahead in the 12 1/4 " hole section to approximately 2,800 metres MD and then setting the 9 (5) /(8) " casing, after which the target Elang reservoir interval will be drilled and logged.

No hydrocarbons are anticipated to be intersected in the 12 1/4 " hole section of the well.

The Buffalo-10 well is being drilled offshore Timor-Leste within the TL- SO T19-14 Production Sharing Contract in a water depth of approximately 30 metres with a target depth of approximately 3,500 metres.

The well is being drilled to test for the presence of commercial quantities of high-quality light oil that is expected to lead to the early re-development of the Buffalo field.

About the Buffalo Project

The Buffalo Project objective involves redeveloping the Buffalo oil field in the Timor Sea. The field resides in only 30 metres of water with a reservoir depth between 3,200 and 3,300 meters below the sea bed.

The previous field proved the existence of very high deliverability reservoir containing high quality light oil that is expected to sell at a premium to Brent in today's market.

RISC Advisory certified the mid case recoverable volume in the Buffalo field to be 34 MMstb (gross, 2C contingent resource), and the primary objective of the Buffalo-10 well is to demonstrate the presence of a significant, previously undrilled attic oil accumulation and for this resource to be converted to 2P reserves.

Furthermore, the CPR developed by RISC in March 2021 has demonstrated that an economic development of the 1C resource of 16 MMstb would be viable down to an oil price of $35. It is therefore considered that there is a strong likelihood that the Buffalo-10 well will confirm an economic development project, with RISC's CPR stating that: "RISC estimate the probability of development to be 86%."

For the above reasons, the Operator is working on plans to compress the timeline to first production once the Buffalo-10 well confirms a commercial oil resource. These plans include engaging with industry for supply and installation of suitable equipment to produce the oil.
