          The technological of Thermo-Gas-Chemical Treatment :

Hydrocarbon reserves of a deposit and the quality condition of the bottom hole formation zone (BFZ) are responsible for the productive capacity of oil, gas and gas condensate wells. The BFZ permeability declines as payout beds get developed and operated.

Why well productive capacity drops:
Colmatation (clogging) of BFZ with drilling mud and cementing mixtures;

Reservoir  gets clogged with asphalt-tar-paraffin deposits (heavy, hard and viscous oil fractions -bitumen, flux, tar, paraffin)
Thermochemical methods can increase hydrocarbon inflow from a production formation via  treatment of oil and gas wells.
Increase of treatment efficiency due to a fast forming of large amount of hydrogen of high penetrability and to the increased energy conversion efficiency of the process.
A combustible oxidizing compound (COC) is pumped into the formation treatment zone and a combustible initiator is then introduced in to treatment zone .

       Advantages of TGC :

  1.       ·        in gas condensate wells - 3 to up to 20 times 
  •               ·        in gas wells - 3 to up to 27 times
  •               ·        in petroleum wells output increases 1.5-7 times
 physical-chemical conditions of heavy hydrocarbons hydro-cracking are achieved:
        .    Temperature is higher than 500 K

        .     Pressure is higher than 30 MPa

        .     Presence of atomic and molecular hydrogen Presence of lithium vapors having high  catalytic   activity        

To provide the operation in a well the same equipment is required as in case of capital repairs.

Fast combustion (for a few seconds) with no detonation. This time suffices for creating new cracks in the formation, but is not enough for causing damage to the bore-hole rig.
Reagents used for thermo-baro-chemical action, and the product of the reaction are ecologically friendly.
Comparable with technology of hydraulic explosion of formation widely applied worldwide; the latter technology being, however, 3-5 times more costly.
All expenses for thermo-Gas-chemical treatment of the hole-bottom region of the formation are expected to be compensated in 2-5 weeks of the operation of a petroleum well.
