“…This is an operational type of control. In addition to the operational type of control, special types of research are used -fieldgeophysical (caliper measuring, all types of logging, resistivity metering) and hydrodynamic (fall-off and build-up tests, study of lost-circulation formations using a packer) [20,21,22,23,24,25,26,27,28]. The practice shows that the implementation of the measures considered solves many issues on the prevention and elimination of fluid losses, reducing their number or decreasing their intensity to 50-90%.…”

Losses of drilling mud and other fluids is the one of the major types of drilling troubles. Annual time losses for their elimination by oil and gas companies are huge. The factors, influencing the mud losses and regulating the direction of the further works, can be divided into two groups: geological and technological. Conducted studies on the use of an insulating composition based on chromium acetate made it possible to identify: the use of the insulation composition on the chrome acetate base allows considerable reduction of time required to eliminate disastrous circulation loss without installation of cement plugs; avoiding BHA replacement; avoiding drilling-in after bullheading and overlapping of lost-circulation layer; low cost, possibility of fast preparation, as it does not entail the delivery of additional chemicals, which also contributes to reduction of time required to eliminate disastrous circulation loss; the use with every type of drilling mud. Basing on the positive experience of the use of this composition in the neighboring regions and considering its economic side, the technique can be used in regions of the Udmurt Republic.
