Extensive studies have been made of the well formations different characteristics such as lithography and petro physical properties. Porosity and permeability have been measured and many core samples were taken and analysed. The reservoir has adverse characteristics (tight). Multiple layers of the reservoir have been tested for oil and gas (hydrocarbons) and indications of hydrocarbons (oil film) has been found in a number of the reservoir levels. The volumes have been small and are not commercial. The drilling rig is being demobilised.

Well Zapadno-Ambarskaya 6

The well was drilled to the target level and penetrated Jurassic 14-15 at a depth of around 2 800 metres. Extensive tests and core samples have been done (see well Yuzhno-Nazinskaya 232). Several layers have been tested for hydrocarbons. The most successful test was done in Jurassic 14-15 which produced around 0,9 m3/day with an emulsion of 50% oil and 50% water. However the productive part proved to be thinner than was indicated by the drilling logs. In Jurassic 7, at a depth of 2687-2691 meters, we tested non-commercial amounts of gas and condensate, Jurassic 1 and Jurassic 3-4 at a depth of 2554 - 2563 meters produced formation water at a rate of 0,65m3/day due to low permeability and porosity. The amounts of hydrocarbons are not commercial.
