Roxi warns of possible three-month testing delay at Deep Well A5 onshore Kazakhstan

Roxi Petroleum has seen further set backs at its Deep Well A5 in the BNG Contract Area of Kazakhstan, with well testing possibly taking another three months to complete after a series of delays

"The continuing delays to the commencement of the 30-day well test at Deep Well A5 are clearly frustrating,” said Clive Carver, Roxi chairman.

“It would be good to be able to demonstrate what we believe to be the case at BNG with solid numbers and also to start banking the revenues from the sale of test production oil. “

Roxi started a 30-day well test at the start of November but the procedure has a hit a number of problems.

It was necessary to clean the well site of drilling fluids. It was decided to do this with coil tubing equipment because of the viscosity of these fluids.

Firstly Roxi had to source the equipment, then the generator from which it was being run broke down, and then the coil tubing became stuck and had to be cut. Roxi are currently trying to retrieve the coil tubing.

The majority of the drilling fluid is now thought to have been recovered to surface. Roxi estimates there are a further 25 cubic metres of remaining excess drilling fluid to be cleared from the well before testing can commence.

Despite the stuck equipment and excess drilling fluid, oil has recently flowed to the surface naturally. There remains the possibility that the natural high pressure in the well will continue to expel the excess drilling fluid, making the recovery of the coil tubing easier.

Should Roxi not be able to remove the stuck pipe it may try to sidetrack the well from a depth of 4,320 metres running a 4.5 inch liner to the bottom of the well and then continue to test on a conventional basis.

Roxi expect this would to take up to a further three months to complete. 

“Nevertheless based on what we have seen to date at Deep Well A5 we believe the deep prospects at BNG contain a substantial reservoir of low sulphur, light grade oil with limited associated gas,” added Carver. 

“Based on this we plan to work steadily over the next two and half years to drill the wells required to maximize the reserves associated with BNG at the least dilution to Roxi shareholders."

The BNG Contract Area is located in the west of Kazakhstan 40-kilometres southeast of Tengiz on the edge of the Mangistau Oblast, covering an area of 1,561 square kilometres of which 1,376 square kilometers has 3D seismic coverage acquired in 2009 and 2010. 

Roxi has a 58.41 per cent interest in the BNG Contract Area.
