Defender US33 #2-29H, Goshen County, WY (SSN 37.5% carried working interest)
Samson Oil & Gas Limited (ASX: SSN; NYSE AMEX: SSN) advises that the replacement pump has been installed in the Defender well and commenced pumping on January 17th. Pump rates have been between 400 to 500 barrels of fluid per day as shown in the following table:
The pump was down for 5 hours on January 20th to fix an electrical fault on the pump jack.
The oil cut over this 5 day period has increased to around 30%. The produced water thus far is largely frac fluid based on regular chemical sampling that is being undertaken and the total recovered load (frac fluid) is 47%.
The Defender US33 #2-29H is the first Niobrara appraisal well in Samson’s Hawk Springs project and is being fully carried by Samson’s farmin partner.
