What is Microbiological Oilfield Reservoir Souring?

Additional downhole pressure is needed to extract oil from a reservoir during secondary recovery. This is typically achieved by ‘water-flooding’ – introducing water into the reservoir through injection wells, to ensure a steady flow of crude oil at the producer.

What is M3 Molten Metal Manipulation?

Calling on more than 20 years’ expertise gained developing bismuth alloy seals for use in some of the world’s most challenging environments, we have created M3 Molten Metal Manipulation: a range of low-melting-point, reversible alloy seals and application techniques for the rapid recovery of leaks and cracks in civil structures, seals, joints, flanges and pipelines, as well as planned preventive maintenance.

Over $100 Million Saved for Leading Operator

Having been advised that a vastly expensive sulfate removal unit (SRU) was essential to prevent future microbiological oilfield reservoir souring at one of its offshore assets, the operator turned to Rawwater for a second opinion.

Key Benefits and Uses

Rawwater’s M3 Molten Metal Manipulation provides unique and unrivalled leak-sealing capabilities across a wide range of highly challenging industrial applications.

Reducing Chemistry Requirement by 20%

Committed to ensuring correct and bespoke chemical dosing strategies, a leading chemical vendor wanted to evaluate the efficacy of its biocidal treatment chemistry for microbiological souring control in the North Sea.

M3 Deployment Methods

M3 deployment methods include M3Spray – a kinetic molten alloy spray which is available with a range of hose lengths for manual or remote application, and M3CollarCast – a process that uses specially designed casting collar moulds for the application of rapidly curing molten alloy seals around pipes, joints and flanges.

Oilfield Reservoir Souring at Early Decision Gate

Wanting to understand the likelihood of oilfield reservoir souring in one of its new discoveries, a leading operator commissioned Rawwater to assess the impact of problematic subsurface sour gas generation.

Establishing the Viability of Shut-In Reservoirs

In light of consistently stable oil prices, a leading operator wished to ascertain the viability of bringing one of its previously shut-in North Sea assets back into service.
