Tamboran Resources Ltd (ASX:TBN) has successfully drilled the Amungee 2H (A2H) well to a total depth of 3,883 metres in the exploration permit 98 (EP 98) area of interest, with a horizontal component of 1,275 metres.
The company drilled the well in the most prospective zone within the Mid-Velkerri “B Shale” formation, where it encountered “significant” gas shows in line with pre-drill expectations.
The well was cased with 5 and a half inch casing, which Tamboran believes is optimal for placing a high intensity stimulation and on par with modern US unconventional drilling designs.
TBN intends to complete up to 24 stimulation stages within the Mid-Velkerri “B Shale”, expected to begin in the first quarter of 2023, subject to weather conditions.
Flow tests to determine gas deliverability
“We are pleased to have drilled and cased the A2H well ahead of budget and schedule,” Tamboran Resources managing director and CEO Joel Riddle said.
“The key objective of drilling, stimulating and flow testing the A2H well over the 1,275-metre horizontal section is to determine the gas deliverability of the Mid-Velkerri ‘B Shale’ in the deeper regions of the Beetaloo Basin.
“The larger casing diameter is expected to deliver sand and fluid at an increased rate to the perforations during the stimulation.
“This is a proven concept that has been known to deliver significantly higher production rates and Estimated Ultimate Recovery (EUR) than smaller casing diameter.
“The drilling operations have been performed safely, with no recordable injuries or reportable environmental incidents to date.
“This is a huge credit to our team, and our contractors, who have enabled a smooth transfer of operatorship since Tamboran’s acquisition of Origin’s Beetaloo assets in early November 2022.
“The location of the second well, which is targeted to be drilled in 2023, is under review. The site will be finalised following the completion of a comprehensive review of the data within the newly acquired EP 76/98/117 acreage.”
Tamboran took the well from spud to total depth in just 38 days for a total cost of $14.1 million, ahead of pre-drill design days and budget expectations.
The company is fully funding the drilling and flow testing of the A2H well, in accordance with the Stage 3 farm-in agreement between Tamboran and Falcon Oil & Gas Australia Limited.
