NACE MR0175/ISO15156


NACE MR0175 / ISO 15156 is the petroleum and natural gas industries standard that addresses the materials for use in H₂S containing environments in oil and gas production.

At OGC Energy we have the Technical Authority to advise on the interpretation and use of NACE MR0175 / ISO 15156 because we are experts in sour environments (production with H₂S).

Our expertise in sour service has been recognised as a member of Task Group 299 on the Oversight of Maintenance Panel for NACE MR0175 / ISO 15156.

NACE MR0175 / ISO 15156 is a legal requirement in several countries including USA, in the UK compliance to this document is a requirement by the Health and Safety Executive. Its interpretation and implementation can be daunting, but our expertise will help you understand the document and its impact to your asset operation.

We are already helping clients to implement NACE MR0175 / ISO 15156 in the following areas:

Regulatory compliance during design and operations:

Operators are responsible for safeguarding the integrity of an installation throughout its life cycle, from design and construction, through operation and maintenance to decommissioning and dismantling. Whenever there is a possibility of H₂S being present, operators need to implement the requirements of NACE MR0175 / ISO 15156. We help operators to comply with this regulatory requirement throughout the life cycle of an asset.

Reservoir souring and its impact on existing assets:

When H₂S levels increase and an asset has not being developed considering sour service, we help operators to evaluate the potential risks and to take informed decisions that meet regulatory compliance, NACE MR0175 / ISO 15156 as well as safeguarding the integrity of their operations. Let us help you assess the risk of reservoir souring.

New product development and qualifications:

Developing a new product and qualifying it to NACE MR0175/ ISO 15156 is one of our core strengths, we help product developers to select materials and qualify products for the harshest downhole conditions.
