Freestone Resources, Inc. (FSNR.PK) Releases Petrozene Lab Test Results

FAIRFIELD, TX--(Marketwire - March 13, 2008) - Freestone Resources, Inc. (PINKSHEETS: FSNR) has been engaged in extensive laboratory and field testing of Petrozene for the past two years. As has been previously discussed, the majority of testing of Petrozene has involved paraffin and asphaltene elimination within tank bottoms, flow lines, production tubing, and formations. During the testing and use of this product we have also found other characteristics of financial importance such as corrosion inhibition, scale removal, the dissolution of iron sulfide and decreasing the viscosity of oil. Freestone has been steadfast in ensuring that all claims of use have been proven to the Board of Directors by either documentable field studies or defined laboratory testing. It is with this mindset that Freestone is now able to reveal the results of our preliminary viscosity testing using Petrozene.

Viscosity is the measure of a liquid's resistance to flow, or its "thickness." The greater the viscosity, thus the greater the "thickness," the more the fluid resists flow. For example, water, which has a viscosity of about 1 cSt at 60° F or about .8 cSt at 100° F, flows quite easily, whereas honey has a viscosity of about 74 cSt even when heated to 100° F, and flows quite slowly in comparison. With regards to oil, crude oil API gravity 48 (condensate) has a viscosity of 3.8 cSt at 60° F whereas a crude oil with an API gravity 13 has a viscosity of about 5400 cSt at 60° F. In other words, the 13 gravity oil is 1350 times more viscous. This viscosity is similar to the viscosity of first drip molasses.

Viscosity is obviously a very important factor with regards to oil production. The simple explanation is that it is more difficult to flow thick, high viscosity oil. Historically, heavy oil reserves, which abound in North America, have been bypassed for lighter oils due to the problems associated with production and refining. Even if the oil was capable of being produced from the well, the oil was often unable to travel by pipeline to refineries due to the thickness, or could only be transported or produced during the summer months when the viscosity was lowered by radiant heat. Methods used in the past to decrease the viscosity of the oil in the pipelines have included pipeline heaters or even adding low viscosity condensate at high concentrations (up to 25%) in order to thin the oil. Some chemical treatments have also been tried, but to our knowledge, none have been economically proven, until now.

Freestone collected a sample of heavy oil from a lease in South Texas for viscosity testing. The oil was sent to FESCO Inc. ( in Alice, Texas along with a random sample of Petrozene from our storage. Testing was done in a two stage fashion, initially all samples were run with the sample oil and Petrozene only, and then the tests were run with the sample oil, Petrozene and a carrier added at a volume to volume ratio of 1%. The results are as follows:

TEST                    RESULTS  UNITS     METHOD     % CHANGE
----------------------  -------  -----  ------------  --------


VISCOSITY                5392     cSt   ASTM  D-445     N/A


VISCOSITY                4311     cSt   ASTM  D-445    20.05%

 @ 60° F

VISCOSITY                4435     cSt   ASTM  D-445    17.75%

 @ 60° F

VISCOSITY                4177     cSt   ASTM  D-445    22.53%

Obviously, Freestone is very pleased with the results of these initial tests and is actively involved in pursuing additional test data regarding viscosity and other applications. At this time, Freestone is currently testing Petrozene with less viscous oils from various geographic locations in order to verify tests already performed by a client that show that Petrozene will decrease lower viscosity oils (1000 - 4000 cSt) at an even greater percent change at even lower concentrations and temperatures. We anticipate publishing these results as verification is achieved. Finally, the Byrd A1 well is now in production and is currently producing at volumes above the capability of the pump, meaning the well is flowing partly on its own. As this well has never produced without artificial lift, we believe the Petrozene treatment has enhanced the drive from this formation. Freestone will release well data in the near future.
