Aurora Oil & Gas Limited (Aurora) is pleased to announce that drilling activities have commenced within the recently acquired Aurora operated Eagle Ford acreage.
The F08 drilling rig from Nabors Drilling has now mobilised onto the Heard Ranch, has rigged up and the JP Heard Bower #19H well was spudded on May 31, 2013. Aurora had previously advised commencement of operated drilling activity was expected in early Q3 2013 and is now pleased to report that the first drilling operations have commenced ahead of schedule. The F08 drilling unit will drill two adjacent wells from the same surface pad location (JP Heard Bower #19H and #20H) and will utilise a batch drilling schedule to further optimise efficiencies.
Batch drilling will result in the rig drilling each surface hole section first, before being re-configured for the deeper build and horizontal sections of the well bore for each well. The JP Heard Bower #20, will first be drilled vertically through the Eagle Ford formation as a pilot hole to allow a local type well log to be recorded, which will be used for geo-steering of the future horizontal wellbores in this area. This well will then be side tracked as the JP Heard Bower #20H horizontal Eagle Ford producer.
Aurora will utilise the knowledge gained through participation in the 289 wells that have been spudded on this and the adjacent Sugarkane Field to optimise the well and stimulation design. The two horizontal wells will be positioned 330ft apart within the reservoir (40 acre spacing) and will be zipper fracced (alternating fracs between the two wells) to improve frac efficiency. The wells are planned for approximately 7,000’ laterals in the target zone and are anticipated to commence flowback during Q3 2013. The same surface well pad will be used for two more drilling locations later in the development schedule. Aurora is presently planning to commence drilling operations with a second drilling rig during Q3 2013.
