Reduced OPEX Costs

Problem Definition

Gas hydrates are one of the major flow assurance challenges for the industry and are expected wherever gas meets water at high pressure and low temperature. Operators typically mitigate the risk of hydrates by continuous injection of chemical inhibitors (methanol or MEG) or by investing in heated pipelines for large subsea fields. These strategies are based on worst-case simulations projected over life of field and result in overdosing of chemicals. This chemical and associated costs can account for between 10% and 20% of annual OPEX costs of a gas field.

“Chemical injection works very well. Methanol is more effective than MEG, but at the same time it is more expensive and more dangerous”

—Service Company, Global

“We have various tie back operations. Recently there has been a lot of investigation into whether we have got the mitigation right, or whether what we are doing is overkill.”—Major Operator, International

“I view the idea of an integrated approach as very, very promising. There is a lot of money to be saved”.

—Consultant, International

How We Solve It

Blue Gentoo has technology which monitors what is happening in the field. It measures the risks of hydrates in real-time, shows how effectively this risk is being managed by the chosen mitigation strategy that is being applied, and provides information for more effective and efficient chemical dosage.

The Technology

HydraCHEK®

Is patented technology which monitors the salt and inhibitor concentrations in the produced water from the first-stage separator to determine the risk of hydrates and/or the safety margin compared to the hydrate dissociation curve for the field.

Benefits

The benefits for the operator are continuous information on what is happening in the field (so greater risk assurance and peace of mind) and the potential for huge OPEX cost savings by managing chemical injection within acceptable safety margins.
