The agency has been brought in following a pitch process revealed by PRWeek, amid fears that the sector is 'widely misunderstood'.
Trisha O'Reilly, director of comms at Oil & Gas UK, pointed to previous experience that MHP had in the sector as one contributing factor towards its pitch success.
She added: 'What we are trying to do is increase understanding of our industry, and as a trade association we tend to focus on our specialist publics such as journalists and those within political process. This is about broadening that engagement and showing our role in economic growth.'
The organisation continues to work with Bell Pottinger for strategic counsel.
