Samson Oil & Gas Operational Advisory

Samson Oil & Gas Limited (ASX: SSN; NYSE MKT: SSN) advises on the following operations:

South Prairie Project (Samson 25% non-operated working interest)

The first well to be drilled in the South Prairie Project, the Matson #3-1 well (located in Ward County, ND), is anticipated to spud on schedule. As previously advised, the drilling contractor CanElson USA was scheduled to mobilize the rig to the well site on June 10th. While a road ban is presently in effect for heavy equipment in this portion of North Dakota due to the spring thaw and heavy rains, it is the operator’s belief that the road ban will be lifted this week so that the rig may be mobilized to the well site. If this occurs, the well could potentially be spud by this weekend. The Matson #3-1 well will be drilled to a total depth of 4,900 feet to test a 420 acre 4-way structural closure in the Glenburn zone of the Mississippian Mission Canyon Formation. The Glenburn zone has produced over 2.5 million barrels of oil just 2 miles to the northeast from a similar type of trap at South Glenburn Field.

North Stockyard (Samson operated North Tier)

The Sail and Anchor 3-13-14 HBK (Horizontal Bakken) well, as reported last week, attempted a side-track at 14,969 feet. The side-track attempt at that depth was not achieved, so it was decided to pull back to 13,400 feet (MD) to side-track in more favorable geology at the top of the target window. The side-track at 13,400 feet was successful, and drilling proceeded over the weekend. Present measured depth is 14,357 feet (MD). Projected TD is approximately 18,000 feet (MD).
