New Patent Addition To The Group's IP Portfolio

Graphene NanoChem (AIM: GRPH), the performance nanochemicals and advanced materials company, is pleased to announce it has filed a patent application in relation to its latest invention of a drilling and completion fluid with an additive capable of maintaining the physical properties of the drilling fluid over extreme temperatures and pressure conditions in both oil and water based drilling systems.

The Group's one-stop additive has a unique multiple capability of:

· improving the rheological properties and rheology of the drilling fluid system over high temperature and pressure conditions without altering other physical properties of the system;

· providing lubricity without addition of conventional lubricants, substantially reducing torque and drag effect during drilling;

· increasing viscosity and yield point of the fluid in extreme conditions; and

· controlling fluid loss to formation during drilling process.

The depletion of "easy" and conventional oil reserves has led to exploration of oil and gas in increasingly challenging environments, extending to sensitive regions, particularly offshore and shale where drilling is carried out under high temperature and high pressure conditions at considerable time and cost. Traditionally a series of additives are utilised by industry to enable the drilling fluid to operate in the extreme situations creating additional costs for both the initial drilling phase and additionally for the waste treatment that follows with stringent environmental standards now becoming the norm for the industry worldwide.

The Group's latest innovation provides the ultimate high performance cost effective drilling and completion fluid, which is also biodegradable and environmentally friendly.

The Group will be seeking to extend the patent protection for its latest invention in selected jurisdictions worldwide.

Jespal Deol, Chief Executive Officer of Graphene NanoChem, commented:

"We are very pleased with this addition to our current IP portfolio, signifying another technological milestone in our oil recovery solutions that enables faster drilling, reduces equipment downtime and improves output level, resulting in significant cost reduction benefits to Big Oil."
