(MENAFN- ProactiveInvestors - Australia) Sun Resources (ASX: SUR) has completed fracture stimulation operations at its second Woodbine horizontal well and the sole vertical well at the Richland Oil Project in Texas.
Operator Richland Resources Corporation has completed 31 successful hydraulic frac stages across the 7,300 feet length of the lateral at John Beeler-1H and will start clean-up and flowback operations this weekend.
These operations are expected to be completed by early 2013.
Fraccing of the John Beeler-2 vertical well has also been completed with six stages across all stacked prospective oil zones, including the Sub-Clarksville, Upper, Middle and Lower Woodbine, the Lower Eagle Ford Shale and the Buda Formation.
Clean up and flow back of this well will be conducted in parallel with the John Beeler-1H and efforts will be made to detect the contributions to well productivity from individual zones.
Meanwhile, clean-up operations on the first well, Beeler-1H, are also continuing with 10% of the frac fluids recovered to date though typically, between 20% and 25% recovery of fluids is required before an accurate, reliable initial production oil flow rate can be established.
A mixture of oil, gas, frac water and fraccing fluids is currently flowing to surface on a very restricted surface choke setting.
Installation of gas-lift equipment has been completed but not yet activated by the operator.
The flowback is expected to accelerate once choke sizes are gradually increase and the gas lift equipment activated over the next 7 days.
Oil produced to surface to date has been sold from the oil tank battery.
The third horizontal well in the current multi-well drilling campaign, Ellis-1H, is expected to be fracced and completed by 12 January 2013.
Sun has a 13.5417% working interest (10.1563% net revenue interest) in Beeler-1H and 16.67% working interest (12.5% NRI) in the other wells.
