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. The increase of treatment efficiency due to a fast forming of a 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 into the treatment zone.
Advantages of TGC:
Physical-chemical conditions of heavy hydrocarbons hydro-cracking are achieved:
vapors having high catalytic activity
