Located in the prolific Cambay Basin, the Cambay field is currently the most significant component in the Company’s portfolio, covering 161 km² (approximately 40,000 acres) in Gujarat State, the industrial heartland of India. 

In June 2021 Synergia Energy Ltd executed a binding sale and purchase agreement to acquire GSPC’s 55% participating interest in the Cambay Production Sharing Contract, providing Synergia Energy Ltd with a 100% working interest in the Cambay concession.

Between 2006 and 2011, the Company conducted an extensive work programme in the contract area, including 3D seismic, five wells and a study to evaluate the application of shale gas technology to the Eocene reservoirs. Netherland Sewell & Associates, Inc. (NSAI), conducted an independent assessment in 2011 which identified significant Contingent and Prospective Resources.

Cambay-73 was originally drilled in 2008 as a vertical well with a single stage fracture stimulation. During an extended production test in 2012 it had a peak production rate of 1MMscfd and 23.5 bbls of condensate.

In 2014, Synergia Energy completed the Cambay-77H horizontal well, achieving significant progress in delivering the following proof of concept objectives:

• Efficient drilling operations demonstrating the repeatability of targeting the EP-IV Zone
• EP-IV Zone reservoir properties lateral consistency, with variability ranges within expectations
• Completion of 4 fracture treatments, albeit 3 fracture zones were thought to be non-productive
• Successfully demonstrated “Plug and Perf” completion technique in India
• First horizontal well in the Cambay Basin with multiple fracture treatments to achieve flowback
• Flowback data used to calibrate horizontal well model for the first time

The key field results from Cambay-77H flowback and production testing were encouraging. The sustained initial 24 hour rate during flowback was 2.03 MMscfe/d, comprising 55% light oil/condensate with concurrent water production of 1,867bbls/d. Flowing wellhead pressure was 1,261 psig. (Rates are presented in energy equivalents converted at 5,800 scf of gas per bbl of oil because the well was originally designed as a gas and condensate producer).The results indicated recovery of significant volumes of oil and gas could be achieved.  Importantly, Cambay-77H and the model, confirm that the tight Eocene formation in the Cambay Field is amenable to this form of fracture treatment, leading to the conclusion that the EP-IV Zone could be commercially developed with this technology.

In April 2022, production from the C-73 and C77H wells was resumed after a hiatus of several years with production being co-mingled through the C-73 production facility. A gas sales contract was executed in April 2022 to market gas to the local low-pressure grid system.

Following the resumption of production in April 2022 and the increase of the Company's working interest in the Cambay PSC to 100% pursuant to the GSPC WI acquisition, a review of Synergia Energy's reserve and resource position was conducted by an independent reserves auditor (RISC). This has resulted in the return of 206 BCP of gas and 8 mmbbls of condensate to the 2P reserves category from Contingent Resources.

Selan Exploration JV

On 14 February 2024 Synergia Energy announced the agreement to farm out 50% of the 100% interest held by the Synergia Group in the Cambay PSC to Selan Exploration Technology Limited (“Selan”).

The Selan JV was approved by the Government of India on 19 July 2024.
