Kulczyk Oil Ventures (KOV), a subsidiary of KUB-Gas, has cased the Makeevskoye-20 well in the Ukraine to a total depth of 2,000m as a gas well, pending completion for commercial gas production.
Drilling at 1,450m was intended to identify the potential of the R8 zone and further develop the Makeevskoye R8 Pool, and to develop the Makeevskoye-21 well during the second quarter of 2012.
In 2011 the Makeevskoye-19 well, which discovered the Makeevskoye R8 pool during drilling in 2010, began production from the R8 zone at an initial rate in excess of 5.5 million cubic feet per day.
The company said the top of the R8 zone in the M-20 well is approximately 20m higher than in the M-19 well, and 36m higher than in the M-21 well.
Drilling indicated a significant increase in gas when the R8 zone was penetrated, and wire line logs indicate that the zone is 18.5m thick, has an average porosity of more than 25% and appears to be completely gas charged.
KOV executive vice president Jock Graham said, "It is the third well in the pool and, once tied-in as a gas producing well later this year, contributions from Makeevskoye-20 will further increase the company's production and revenue from Ukraine."
The Makeevskoye-21 well, located 2km west of the Makeevskoye-20 location, was tied-in for commercial production at the start of August at a rate of 1.7 million cubic feet per day.
A drilling rig which drilled the Makeevskoye-20 well is scheduled to move to the Krutogorovskoye-7 well located near the city of Lugansk in late August, to commence drilling at site to a TD of 3,058m to evaluate the potential of Moscovian and Bashkirian zones in a new structure defined by seismic.
The rig is owned and operated by KUB-Gas, which is 70% owned by KOV.
