French multinational contractor SNF Flopam has won new enhanced oil recovery work for India’s state-owned giant Oil & Natural Gas Corporation.

SNF Flopam India will carry out a polymer injection project at ONGC’s Bechraji heavy oil field on its Mehsana asset in Gujarat to boost recovery of the viscous crude.

The contractor noted this project, which comprises 11 injector wells and 13 new producers, envisages continuous injection of around 50 cubic metres per day of polymer per day per well for 27 months.

SNF will lease to ONGC polymer injection modular skids for the mixing, hydration and injection of a polymer solution and also be tasked with their operations and maintenance on a turnkey basis.

The surface facilities for this EOR project will be installed at the Bechraji gas gathering station GGS-II during a mobilisation schedule of five months, which SNF described as “challenging”.

The contractor earlier this year secured polymer flooding EOR work worth $6.5 million at ONGC’s Jhalora field, also located onshore Gujarat, western India.

Jhalora was brought on stream in 1977 and has 102 producing wells. At this asset, SNF will inject alkali surfactant polymers (ASP) into 14 wells in an 18-month campaign.

Causing concern

“It [Jhalora] is a light oil field but water cut is causing concern. We want to use ASP to reverse the decline and increase recovery,” SNF quoted an ONGC official as saying.

SNF’s new manufacturing facility at Ghanhidham in Gujarat can produce 120,000 tonnes per annum of acrylamide, 60,000 tpa of poly acrylamide powder, 42 tpa of poly acrylamide liquid and 36,000 tpa of poly acrylamide emulsions.

The company is no stranger to working in India, having earlier secured EOR contracts for Cairn at Barmer in Rajasthan and at ONGC’s North Kadi oilfield in the Cambay basin.
