First Purchase Order from a new Texas based distributor

Hydrocarbon Dynamics Limited (“HCD”) ( ASX: HCD ) announces that it has received an initial Purchase Order from a new Texas based distributor. The distributor’s client will use HCD Multi-Flow in more than one application in the highly paraffinic Uinta Basin of Utah to test its efficacy controlling production and operating problems associated with the ‘green wax’ of the Uinta Basin. Wax issues are so severe that crude oil must be transported to refineries via heated trucks and production fields suffer from wax deposition and high crude oil viscosity related issues. This represents a prime opportunity for HCD to showcase its exclusive chemistry.

This basin has been specifically targeted by HCD as part of its ongoing strategy to focus on regions and basins that utilise high volumes of paraffin inhibitor and remediation chemical usage and where HCD’s unique technology can demonstrate its efficacy.

The initial PO is for ~$11,000 of product.

Release approved by the Board of Directors.
