(MENAFN- ProactiveInvestors - Australia) Empire Energy Group (ASX: EEG) has brought another Kansas development well it drilled in 2012 into production and has recorded higher production from a well that underwent polymer treatment.
The Siefkes A1-13 well is currently producing 19 barrels per day (bpd) of oil from the lower Arbuckle zone though log data indicates the optimum zone is the Upper Arbuckle.
Once current production drops to 2-3bpd, the Lower Arbuckle will be plugged and the Upper Arbuckle perforated for production.
Empire also continues to show production improvement at its Kollman-14 well, which has undergone polymer treatment to improve output.
Kollman-14 is now producing about 19bpd, up from 2bpd prior to the treatment, with payback for the treatment expected in about six months.
Up hole completions
The 10 producing wells completed over 2011 and 2012 have initially focused on the entire Arbuckle formation, which is strongly water driven.
With the exception of Wells 1 and 2 that were drilled in early 2011, the other eight wells have not yet tested the Upper Arbuckle (where it occurs), the Lansing â€" Kansas City ("LKC"), Viola, Big Springs and Toronto formations (where applicable).
These formations tend be less water prone and have significant potential for oil production, particularly in the LKC and Viola formations.
As the oil cut in the Arbuckle formation of new wells reaches a less than optimal level, the well will be plugged at the Arbuckle formation and then targeted up-hole formations perforated and produced.
