PWI examples of realization

The pulse-wave impact technology successfully solves problems:

  • increase the productivity of producing wells;
  • increase injection capacity.
Bellow are examples of PWI using in various fields.

INCREASE THE PRODUCTIVITY OF PRODUCING WELLS

EXAMPLE. INCREASE THE PRODUCTIVITY OF PRODUCING WELL IN ZAPADNO-OSTANINSKOE OILFIELD

Zapadno-Ostaninskoe oilfield is characterized by complex geological conditions associated with low-permeability reservoirs and low oil-filled thickness.

BEFORE PWI

Prior to treatment producing well №X1 (in Zapadno-Ostaninskoe oilfield) working conditions is gradually decreased, and prior the treatments by PWS technology were: liquid rate = 29 m3 / day and oil-production rate = 27tons / day.

AFTER PWI

After treatment working conditions multiply increased and amounted: liquid rate = 56 m3 / day and oil-production rate = 49 tons / day. In the first 2 months after treatment water cut slightly increased and then stabilized.

The positive effect duration was 29 months, during which on independent scientific assessment* was additionally produced 8864 tons of oil.

INJECTION CAPACITY INCREASING

EXAMPLE. INJECTION CAPACITY INCREASING IN PRIOBSKOE OILFIELD

Priobskoe oilfield is characterized by producing horizons complex geological structure as in area and in cross-sections. For producing horizons collectors customary:

  • low permeability;
  • low gross sand;
  • high clayiness;
  • high stratification factor.

BEFORE PWI

Prior treatment №XX32 well for a long time worked with injectivity lower than 130 m3 / day.

AFTER PWI

After processing well injectivity increased to 252 m3 / day at constant wellhead pressure.

The positive effect lasted about 24 months. During this on the results of internal Customer assessment was additionally produced more than 7,700 tons of oil.
