OIL services firm RHEOCHEM made a confident stock market debut yesterday.
Shares in the company, which supplies drilling fluids and engineering services for Australia's oil and gas market, rose 3p to 19.
That values Rheochem, founded in 1995, at £17.1million.
Chief executive Haydn Gardner said the £4.7million raised from the flotation will go towards expanding into regions like Nigeria, New Zealand and India.
He added: "Our continual development of cutting-edge products puts us in a very strong position to become a significant supplier to the international oil and gas exploration industry."
