Abstract

During development of hydrocarbon reserves, stable aggregative systems – water-in-oil emulsions and bottom sediments – form and accumulate in flow tanks at oil production units impairing, thus, stock tank oil quality. The common practice of disposal of these systems using outsource services results in loss of valuable hydrocarbons.

Specialists of TatNIPIneft Institute have developed effective technologies to break bottom sediments and stable water-in-oil emulsions stabilized by solid particles in flow tanks.

The technologies of thermochemical and acid treatment aim at breaking of stable water-in-oil emulsions, the technology of treatment using diluent is effective for breaking of bottom sediments. The technologies were successfully tested at the Company’s facilities.

Commercialization of these technologies will allow the Company to cut down expenses related to disposal services; also, the volume of additional on-spec oil will be increased.

Key words:

stable water-in-oil emulsion, bottom sediments, blending, treatment technologies
