What We Do

Xpert Opinions is a web based technical discussion forum through which facilities engineers within the oil and gas industry may access a range of consultants with deep technical competencies and experience. 

Xpert Opinions aims to create a “back-pocket” facilities engineering function accessible to all registered members of the forum. Xpert Opinions is of particular relevance to small and medium sized oil and gas operators and service companies who may not have ready access to a full complement of technical authorities.

Consultants will typically be subject matter experts in their respective engineering disciplines. They will be members of a professional engineering institute, either at chartered or fellow status. Our intent is to maintain a balanced, yet comprehensive and multi-disciplined community of consultants. Numbers will therefore flux with demand and we will occasionally seek to engage further consultants through a structured selection process.

Our Discussion Forum

Our Technical Discussion Forum is now open for membership. Click here to access the login page to the forum.

The Xpert Opinions Technical Discussion Forum has no restriction on membership and no enrolment or subscription fees. The purpose of the forum is to promote dialogue amongst its members, including  guidance and advice on common technical issues, sharing of best practice, experiences and lessons learned, and the ability to seek expertise from the forum when required. 

Prospective members initially need to register with the forum. Once complete, members are able to create posts visible to all members of the discussion forum. Threads and any subsequent posts are moderated in accordance with forum guidelines. Posts are also be categorised by engineering discipline and subject matter such that our data base of previous threads may be easily searched.
