PetroNeft All Smiles over Arbuzovskoye Production Rates
PetroNeft Resources plc, owner and operator of Licences 61 and 67, Tomsk Oblast, Russian Federation, provided the following update on its operations at Licence 61.
Licence 61 - Arbuzovskoye Pilot Development Program
Arbuzovskoye well 105, the sixth well in the current program, has been successfully tested at an initial rate of 160 bopd with no visible water cut.
Further to last month's update, pressure testing of two wells at Arbuzovskoye was carried out which indicated that reservoir pressures are in line with expectations based on volumes produced to date. This confirmed that the rapid decline in production experienced in the Arbuzovskoye 102 well in January and February was due to a near-wellbore problem resulting from likely migration of fine grained materials that had plugged the perforations and was not due to problems with reservoir pressure. As a result an underbalanced re-perforation of the Arbuzovskoye 102 well was performed, which successfully removed the flow restrictions in the well and restored production to 380 bopd.
Following the success of this remediation procedure, other Arbuzovskoye wells are currently being examined with a view to re-perforating additional wells in the near term.
A water source well has now been drilled to supply injection water for the planned pressure maintenance program at Arbuzovskoye. Locations and timing of further production wells will be selected based on the response to the pressure maintenance program. The objective is to optimize recovery from the field and allow the pressure maintenance system time to get established. It is likely that at least three additional wells will ultimately be drilled from Arbuzovskoye Pad 1 to fully exploit the area.
Arbuzovskoye contains 2P reserves in excess of 13 million barrels of oil according to independent reserve auditors Ryder Scott and is the Company's second field being developed.
Licence 61 - Production
Total oil production, comprising both the Lineynoye and Arbuzovskoye oil fields has increased up to 2,800 bopd after successful completion of 105 well and re-perforation of 102 wells at Arbuzovskoye.
Dennis Francis, chief executive officer of PetroNeft Resources plc, commented:
"Development work at Arbuzovskoye has been positive this past month. Not only has the pressure testing of two wells confirmed normal pressure decline for the field in line with production, but the workover of well 102 was successful. We will now implement the planned pressure maintenance program on the field which will slow production decline and improve recoveries. A similar program was implemented at Lineynoye field where we had positive results."
