Samson Oil & Gas Limited has reported an update on its Hawk Springs project in Goshen County, Wyoming.

Bluff 1-11 (SSN 25%)

The Bluff 1-11 well was perforated within the 9,500 sand over the interval 7,738 to 7,754 feet, and the well unloaded the completion brine almost immediately and flowed non inflammable gas at a rate of 8 MMcfpd. The rate was relatively constant during the 41 hour flow period. The well flowed on a 20 or 21/64ths inch choke at a tubing pressure of between 2,500 and 2,600 psig that increased during the flow period. No formation water was evident. Gas samples were taken and are in the process of being analyzed. The well is currently shut in for approximately 10 days whilst the pressure response is measured.

The gas flow was not able to be ignited, and based on our previous samples was most likely largely nitrogen as determined from the analysis of the wire line logs.

The test was designed to achieve several objectives all of which have been achieved or are expected to be achieved:

1. To prove that a trap at the Bluff prospect exists, this has been demonstrated with a flow rate that was sustained during a lengthy flow period. This enables the possibility of an oil leg being present down dip of the nitrogen intersected in this well bore.
2. To prove that the 9,500 sand was a viable reservoir, such that if an oil leg was present it could be produced.
3. To enable clinical samples to be taken particularly for the presence of helium which is often associated with nitrogen in natural gas reservoirs. These samples will also determine whether the nitrogen has an organic source or not.
4. To determine through transient pressure analysis the presence of any fluid or reservoir boundaries.
5. To determine reservoir characteristics such as reservoir pressure and permeability.

The data being collected in the near term includes the shut in pressure data, and the sample analysis. This process is expected to take three weeks after which we will have a clearer view as to the possible commercial benefit of this discovery.
