Oil Council North America Assembly

Velocys (VLS.L), the smaller scale gas-to-liquids (GTL) technology innovator, is pleased to announce that Roy Lipski, CEO, will be joining other industry leaders in providing insight on key strategic energy-related topics at the prestigious Oil Council North America Assembly in Houston, Texas next week.

Roy Lipski's presentation is scheduled for Tuesday 22nd October at 3.30pm CST.

As the development of shale plays in North America continues, driving the price of natural gas to $4/mmbtu and below, much attention is being focused on the implications of the low gas price in comparison to other energy commodities. At the OilCouncil panel discussion "Natural gas, LNG, GTL: North America's opportunity", Roy Lipski will highlight how smaller scale GTL is uniquely placed to capture these price spreads and realise high value from shale gas and other gas resources. Alongside him on the panel will be senior representatives from other companies such as Sasol.

Roy Lipski, CEO of Velocys, said:

"Multi-billion dollar conventional GTL projects are an option for only a handful of large players at only a few locations. Smaller scale GTL, based on the use of Velocys technology, opens up the market to the majority of energy companies. We see worldwide opportunities for smaller scale GTL; whilst in North America, it is an especially good fit for the challenge of monetising remote or low-value gas resources of 10 million scf/day or more, from either conventional fields, shale or associated gas."

A copy of Roy Lipski's presentation can be downloaded from the Velocys web site from Monday 21st October.
