Gravis Oil Corporation Grassy Creek Technology Update

CALGARY, July 25, 2011 /PRNewswire/ - Gravis Oil Corporation., (the "Company"
or "Gravis"), (OTCBB:GRAVF) which holds a major position in the western
Missouri heavy oil development play, completed the drilling of a new
development pattern at its Grassy Creek operations at the end of April
2011. The Company's development strategy incorporates the use of modern
technologies to increase cost effective production by minimizing
lifting costs and improving recoverable reserves per net acre. Gravis
is employing advances in chemistry, real time data measurement and
drilling techniques to achieve these operational goals.

Gravis intends to provide periodic updates regarding the deployment of
these advanced technologies and comment on the progression of operating
and production results. Steaming of the new Grassy Creek development
pattern, consisting of an injection well, two observation wells, and
six producing wells on approximately a one-third of an acre site began
in early May, 2011.

Surface Facilities and Equipment

Due to the complexity of producing heavy oil, selecting economic and
cost effective solutions for high pressure-high temperature production
equipment is critical. During the past six months, Gravis Oil has
completed an extensive field evaluation and redesigned and successfully
installed surface and downhole equipment that is expected to reduce
downtime and lower lifting costs.

The previous downhole and surface equipment utilized at the field was
replaced with durable and modern equipment designed for harsh
temperatures associated with heavy oil operations. The efficiency of
lifting equipment was improved in both durability and operability to
reduce complications associated with the steam flood and heavy oil
fluids. Downhole pumps were replaced and fitted with anti-gas locking
devices as well as metal to metal seals designed for high temperature
operation. These changes will reduce the frequency of maintenance and
boost pump efficiency. Wellhead equipment has been modified to
accommodate instrumentation deployment and chemical stimulation, and
includes well control devices that will allow flexibility to safely
work over existing wells and drill new patterns without associated
interruptions of adjacent production.

Surface and field piping were optimized as well to handle increased
volumes of produced fluid. Larger diameter well production piping was
installed to improve flow of heavy oil, along with heat tracing and
insulation to improve winter performance. Piping systems were modified
to allow for re-injection of hot produced water to conserve heat and
pressure energy thereby reducing full-cycle purchases of natural gas.
Equipment is being installed to re-capture energy from produced fluids
to further reduce the cost of steam generation.

Tim Morrision, the Company's chief executive officer, stated: "We are
extremely pleased with the progress that we have made at Grassy Creek.
Our commitment to produce heavy oil reserves with attractive economic
returns to our shareholders is our primary goal. The Company will
continue to discover, procure and deploy technologies that will reduce
the operating costs associated with heavy oil production while
maintaining or increasing capacity and efficiency".

Since steam injection began in the new Grassy Creek development pattern
in early May, Gravis field personnel have measured a significant
increase in reservoir temperature, and encouraging early stage
production response. The Company estimates that it may take until late
August, 2011 to fully assess the results of the new development
