Oilex Limited (Oilex or the Company) is pleased to announce the following update with respect to the re-classification
of Cambay gas and condensate volumes to reserves and increase in resources.
Summary
1. A review of Oilex’s net reserve and resource position in the Cambay PSC by an independent reserves auditor has resulted in the return of 206 BCF of gas and 8 million barrels of condensate to the 2P Reserves category from Contingent Resources.
2. Oilex’s participating interest in the reserves and resources has increased from 45% to 100% following its
purchase of GSPC’s share of the project.
The revised reserve and resource position showing the re-allocation from Contingent Resource category to Reserves
and the increase in volumes from the GSPC acquisition is shown in Tables 1 and 2:
Reserves (Oilex WI %)
At 1 June 2016 (45%):
Gas (Bscf)
1P:0 2P:0 3P:0
Condensate (MMstb):
1P:0 2P:0 3P:0
At 1 June 2022 (100%)
Gas (Bscf)
1P:0 2P:206 3P:377
Condensate (MMstb):
1P:0 2P:8 3P:17.3
Contingent Resources (Oilex WI %)
Gas (Bscf)
1C:215 2C:417 3C:728
Condensate (MMstb):
1C:12 2C:27.4 3C:54.6
At 1 June 2022 (100%)
Gas (Bscf)
1C:388 2C:720 3C:1239
Condensate (MMstb):
1C:23.7 2C:52.8 3C:104
Background
In April 2015, the Company tabled a Resource Report on the Cambay Field Eocene gas and condensate reservoir which
is the same reservoir that hosts current oil and gas production and that is the focus of upcoming re-frac of the C-77H well as reported in recent announcements. The resource report was prepared by independent oil and gas advisors RISC and allocated recoverable gas and condensate volumes across Reserve, Contingent Resources and Prospective Resources categories. In June 2016, due to changes in economic assumptions specifically a fall in world oil and gas prices and the then impasse with GSPC deferring field development activities, the Reserves component of the overall gas and condensate volumes was re-classified to Contingent Resources while the aggregate Reserve and Resource
volumes remained unchanged.
RISC has again reviewed the recent material changes to the circumstances surrounding the Cambay project which remove the previous impediments to progress on the project development. These changes include the following:
1- Grant of a PSC term extension to September 2029 by the Indian government
2- Approval of a Field Development Plan for the Eocene reservoir by the Indian regulator (the Directorate General of Hydrocarbons)
3- Resolution of the joint venture impasse through Oilex’s purchase of GSPC’s participating interest taking Oilex’s participating interest to 100%
4- Recommencement of gas and condensate production from the Eocene reservoir with delivery of gas to buyers under a new gas sales agreement
5- Issue of new Environmental Clearances by the Indian government
6- Oilex’s commitment to the required work program to develop the resources including advanced planning and contracting for a re-frac of the C-77H well planned to commence in July 2022
7- Improvements in economic factors including the high current global and Indian oil and gas prices and the high demand for petroleum products in India.
As a result the contingencies for development identified in 2016 have been resolved and RISC consider that the Reserves re-classified as Contingent Resources in 2016 can now be reclassified as undeveloped Reserves, justified for development as shown in Table 1. The company’s net volumes have also increased following the GSPC acquisition as shown in Tables 1 and 2. At this point in time the 1P allocation is zero. Under the Society of Petroleum Engineers Petroleum Resource Management System (PRMS) the 1P volumes may be attributed once capital has been spent and a commercial analysis has confirmed a positive NPV10. Oilex intends that 1P volumes will be added at the appropriate time. r>
Oilex’s Chief Executive Officer, Roland Wessel, commented:
“The return of the volumes from contingent resource to reserve classification and the increase in overall volumes reflect the very significant and positive advances made by the Company over the last 12 months. The current efforts to re-frac the C-77H well and increase production levels are on schedule and it is expected that equipment will be mobilised to the
Cambay field in June with the re-frac flow back testing scheduled for July. Current production at C-77H confirms the presence of gas and condensate within a tight formation and specialist advice received on implementing a re-frac stimulation suited to the geology of the formation will provide the best opportunity to realise commercial gas flows. A successful outcome will allow further field development to be undertaken to address the large gas and condensate
volumes that have been identified.”
