Cairn India starts polymer injection in its Mangala field in Rajasthan

Cairn India, one of the largest independent oil and gas E&P companies in India, has initiated polymer injection at the Mangala field. 

Enhanced oil recovery (EOR) project

The Mangala enhanced oil recovery (EOR) project, which is amongst the largest polymer flood EOR programmes in the world, commences well ahead of the guidance provided by the company. The polymer injection activity would gradually be ramped up. 

The operator recognised the potential for chemical EOR at an early stage of development in its Mangala, Bhagyam and Aishwariya (MBA) fields. The reservoir quality, oil properties and ambient temperature make these fields ideal for the application of chemical flooding EOR methods such as polymer or alkaline surfactant polymer (ASP) flooding. The chemical EOR programme has a potential to enhance recoveries from the Mangala, Bhagyam and Aishwariya fields by around 300 million bbls.

Successful pilot programme

The Mangala ASP pilot programme, the next phase of EOR has also yielded excellent results so far, suggesting better mobilisation of oil post polymer flooding.

Sudhir Mathur CFO Cairn India, commented: “Injecting the polymer at our world class polymer flood EOR project, ahead of schedule is a testament to our execution skills and team work. This will enable us to further unlock the potential of the prolific Rajasthan block and help contribute significantly towards the nation’s energy security.”
