London listed Regal Petroleum announced the initial testing results of the VAS-10 well located at its Vasyschevskoye (VAS) gas and condensate field in Ukraine. The VAS-10 well was spudded in March 2018 and drilled to a depth of 3,380 metres. The well is located to the north-west of the field, at an offset of approximately 1 kilometre from the nearest producing well, and targeted two reservoir zones in the Visean formation: the B-16/17 and the deeper B-25/26. The B-16/17 reservoir is currently the main production horizon in the VAS field. One interval, at a depth of 3,219 – 3,224 metres within the B-25/26 reservoir, has been perforated, and short-term initial flow testing of this interval was undertaken using a variety of choke sizes. During this initial testing, the well flowed gas but was not able to establish a stabilised flow rate. The drilling rig has now been released and is being demobilised from the well site. Thereafter, it is intended to hook up the well to the gas processing facility and undertake longer-term production testing of the abovementioned reservoir interval. Depending on the outcome of such testing, either this interval will be put into production, or alternatively the shallower B-16/17 reservoir will be tested
Regal Petroleum has two gas and condensate development projects in Ukraine, comprising the Mekhediviska-Golotvschinska (MEX-GOL) and Svyrydivske (SV) fields, and the Vasyschevskoye (VAS) field. The fields are located, geologically, towards the middle of the Dnieper-Donets sedimentary basin which extends across most of north-east Ukraine. The vast majority of Ukrainian gas and condensate production comes from this basin. The fields were originally discovered in the 1960s during the Soviet era, with wells being drilled sporadically over the years since then by State companies, prior to Regal’s involvement.
