NETHOD OF PRODUCTION OF HIGHLY PARAFFINIC CRUDE Russian patent published in 2009 - IPC E21B43/22 

FIELD: oil and gas production.

SUBSTANCE: invention refers to oil industry, particularly to methods and installations for production of highly paraffinic crude. According to the invention of production of highly paraffinic crude it consists in supply of chemical reagent into bottomhole zone of the reservoir and in withdrawing product - oil or oil containing reservoir fluid; also chemical reagent is supplied at consumption of 0.3-5.0 kg per ton of the said product via a capillary tube with internal diametre 3-7 mm under pressure up to 40 atm; the capillary tube is connected with a power cable along the whole length of the well; the capillary tube and the power cable are introduced into the well through a leak proof cable input; they are protected from direct contact with internal surface of the well with protectors; notably, agent "Glade" is used a chemical reagent.

EFFECT: increased efficiency of wells with simultaneous simplification and reduced cost of production of highly paraffinic crude and oil containing pyrobitumen and resin and their transporting.
