Geological and process surveys

In 1984 the geological engineering survey team was formed on the basis of the mud logging team, subsequently, in 2000, it was reorganized as the geological engineering survey expedition of Bashneftegeofizika JSC. In 2011 all GTS teams of other Bashneftegeofizika JSC departments were consolidated on the basis of the geological and technical survey expedition, Ufa Administration of Geophysical Works.

Geotest-5 GTS station

Geotest-5 GTS station is designed for:

automated gathering of geological and geochemical and process information while drilling;
control over drilling parameters;
situation assessment and emergency and troubles prevention;
reservoir designation and assessment of saturation nature;
drilling process documentation, drill site data transfer.

Application area: geological engineering surveys and control over well drilling for oil and gas.

Operation of Geotest-5 GTS station at the well site enables well remote monitoring.
