ONGC powers R&D drive to help country cut oil imports

ONGC on Wednesday entered into an MoU with Super Wave Technology Pvt Ltd (SWTPL), a company incorporated by the Society for Innovation and Development, Indian Institute of Science (IISc), Bengaluru, for carrying out research and development (R&D) on alternative technology for hydraulic fracturing.

The historic event at IISc, Bengaluru, was attended by Prime Minister Narendra Modi, Minister of State (Independent Charge) for Petroleum & Natural Gas Dharmendra Pradhan, oil & gas secretary Sourabh Chandra, ONGC CMD Dinesh K Sarraf, Director (Technology & Field Services) Shashi Shanker, IISc Director Prof Anurag Kumar and SWTPL Director Prof Gopalan Jagadeesh. The MoU was signed by Shanker on behalf of ONGC and Prof K P J Reddy on behalf of SWTPL.

With this partnership, ONGC will provide assistance to SWTPL for developing Shock Wave-Assisted Fracking Technology, an alternative to conventional hydraulic fracturing which, if proven effective as a substitute to hydraulic fracturing — in particular for shale gas exploitation — will be a game changer for the oil & gas industry.

Hydraulic fracturing needs huge amounts of fresh water and energy for pumping at very high pressures. After hydraulic fracturing, a well produces substantial quantities of effluent water which need to be disposed. The global oil & gas industry has been searching for an alternative technique for fracturing which would require little or no water. Shock waves are one of the most efficient energy dissipation phenomena. The sudden release of massive amounts of energy in a miniscule space domain triggers the formation of these waves. The impulse generated by these waves can be used for many interesting and innovative applications.

In the project with ONGC, SWTPL proposes to use shock/ blast waves for initiating fractures/
features in sandstone/ shale reservoirs located initially at depths of 1,000-1,500 m. The MoU signed on Wednesday would provide an impetus to the development and field implementation of shock waves technology for oil & gas fields.
