Oilex unveils favourable fracking analysis for Cambay

Oilex unveiled positive results from the large gas resource at the company's Cambay project on Thursday.

The analysis, completed by both tight gas experts at Schlumberger and Baker Hughes, confirmed that siltstones at Cambay could be effectively stimulated as part of the fracking process and that commercial gas flow rates were potentially achievable.

Managing director Joe Salomon said that the findings had confirmed the importance of implementing a tailored approach.

"We are very pleased that the review and analysis has confirmed the substantive potential of the EP-IV reservoir at Cambay, and that it has provided specific solutions to be employed in the execution of future drilling and well completion programmes.

"These findings have confirmed the importance of implementing a tailored approach to unlocking the potential commercial success of the large gas resource at the company's Cambay project".

With Schlumberger carrying out the testing, the report from Baker Hughes indicated various important details for the fracking process at Cambay, such as that the reservoir rocks had the essential characteristics for the development of suitable fractures required to increase exposure to the reservoir as well as to enhance gas flow rates under production.

Also the report noted that proppant selection will be crucial to the maintenance of the necessary conductivity for sustained production.

Proppants are a solid material, typically treated sand or ceramic materials, that are designed to keep an hydraulic fracture open, during or after its has been fractured.

Additionally, the report felt the fractures within the overall reservoir section were particularly critical to attaining optimum fracture length and direction, as well as to ensure that the fractures were constrained within the reservoir section.

Finally, that reservoir temperature and pressure offered no direct challenges to adding the stimulation technologies.
