Cub Energy has declared that it has started drilling the Makeevskoye-20 (M-20) well. KUB-Gas is operating this M-20 well. It is a subsidiary, wherein Cub has a 30% ownership stake.
Cub Energy expects that the expansion of the M-20 may take between 40 and 50 days in order to achieve a proposed total depth (TD) of 1,982 m through the help of KUB-Gas’ K-200 drill rig.
The M-20 well will appraise the R8 sands at about 1,450 m of depth. Originally, the Makeevskoye R8 pool was identified in the Makeevskoye-19 (M-19) well that was drilled during the second half of 2010. It was additionally expanded by the Makeevskoye-21 (M-21) well that was drilled during Q2 of 2012.
The location of the M-19 well is about 1 km towards the western part of the M-20 well site. This well started production at an initial rate of more than 5.5 million cubic feet per day (MMcf/d) from the R8 zone during July 2011. The M-21 well is situated about 2 km towards the western part of the M-20 site and examined 3 MMcf/d of natural gas obtained from the R8 zone during June 2012.
According to Cub Energy’s CEO and Chairman, Mikhail Afendikov, the company is confident about the potential of this well. The M-20 well reflects the company’s present concentration on low-risk improvement of its underexploited and proven assets. It is situated about 1 km towards the southeastern part of the M-19 well.
The company has planned to expand by purchasing huge undeveloped license regions that are adjacent to the present production, thus reducing the risk of exploration, and expanding these regions by combining western technology, seismic, local knowledge and modern completion practices.
