Slater Dome Federal 24-9 Well
Since fracture stimulation on August 16th, 2012 the well has recovered approximately 61% of the injected frac fluid volume. It was not until August 27th that the natural flow had abated to the degree that the downhole pump equipment could be safely run into the hole and set. Higher gas content of the oil in this zone has complicated initial pump settings, and consequently, the pump has only been run intermittently to date.
Battle Mountain 14-10 well
The 14-10 well has continued to produce on pump, but influx has remained at a relatively unstable daily rate. However, current indications are that the production rate is stabilizing at around 8BOPD. Whilst this rate is at the low end of expectations for the Niobrara Benches in this area, this may be the result of higher shale content, and lower natural fracture density observed on logs across this bench in this particular well. Certainly, in these attributes (shale content and natural fractures), this bench, in this well appears inferior to the others planned for fraccing. The results
so far will prove a valuable calibration point enabling more diagnostic log interpretation and future determination of candidate intervals for fracture stimulation and treatment design.
C&C Cattle 18-8 well
The fracture stimulation of this well has been tentatively re-scheduled for September 10th due to the fracture stimulation crew being delayed because of operational problems on their current job for a different operator.
In our first round of fracture stimulations our plan is to stimulate the Niobrara A zone in the Slater Dome Federal 24-9 well; the Niobrara B/C zone in the Battle Mountain 14-10 well; and the Niobrara D zone in the C&C Cattle 18-8, after which we should have a good estimation of the total potential of the full Niobrara section penetrated in a vertical well. The zones in 14-10 and 24-9 have now been successfully fracture stimulated. Fracture stimulation of the Niobrara D zone in the C&C Cattle 18-8 (C&C 18-8) is scheduled for late this week.
There are four distinct hydrocarbon bearing zones within the Niobrara and additionally potential in the underlying Frontier Sandstone and Mowry Shale. All of these intervals have previously produced oil and gas from wells within Entek’s acreage position.
The Entek Appraisal Program is seeking to gain production characteristics from all Niobrara zones. It is important to note that, in each well, each zone only represents a portion of the total Niobrara
