The term “formation of an open face” refers to the creation of well completion technologies, which are combined to a gradual deepening of the wellbore in the project horizon with simultaneous waterproofing aquifers, hardening of unstable rock intervals and preservation of porosity and hydrocarbon saturation properties of interlayers.

The trend complication geological and field conditions completions in the late and final stages of oil and gas development toughens requirements for quality tailing deposits, tightness lining and hydrodynamic design excellence bottom wells.

To solve arising in this complex technical problems in the abnormal geological and field conditions of technogenic origin in recent years is technology that combines the processes of destruction of rocks and deepen the bottom of wells with permeable walls mudding trunk in different ways

To this end, developed advanced in permeable formations colmatation screens of different functionality, which can be divided into two main classes:

Technology of deep colmatational areas with long-term and irreversible insulated reservoir fluids;

Technology of shallow (penetration into the formation) shielding, temporarily protect reservoirs from the infiltration of process fluids and their effluents.

The paper considered three technologies:

The technology of selective treatment fluid jetting Fat productive technology is intended for long-term isolation of permeable formations unsealed as in the conventional technology (for repressionnom or pressure balanced), and jetting technology;

Technology “gentle” mudding in the process of deepening the face and a device for its implementation;

Primary drilling technology using struyno- wave kolmatatora and material “quartz”.
