Title:
MULTI-CHARGED IONIC COMPOUNDS DERIVED FROM POLYAMINES AND COMPOSITIONS THEREOF, AND USE THEREOF AS REVERSE EMULSION BREAKERS IN OIL AND GAS OPERATIONS
Document Type and Number:
Japanese Patent JP2023093458
Kind Code:
A
Abstract:
To provide methods and corresponding reverse emulsion breaker compositions to make separation of oil/hydrocarbon from water in a produced fluid in oil and gas operations more efficient and effective.SOLUTION: As a reverse emulsion breaker composition (REB), a novel class of multi-charged cationic or anionic compounds is used, which is derived from an aza-Michael addition reaction between a polyamine (Michael donor) and an activated olefin (Michael acceptor). The REB is effective in separating oil/solid from water. The activated olefin (Michael acceptor) has an ionic group according to one of the following formulas (I), (II) and (III), where X is NH or O.SELECTED DRAWING: Figure 1
