TL;DR: In this article, the surface and interfacial properties of five zwitterionic surfactants, including three propyl sulfobetaines CSB (where the carbon atom number of the alkyl chain is 12, 14 and 16, respectively) and two hydroxypropyl sarsobetaine surfactant CHSB (with carbon atom numbers 12 and 14, respectively), were studied at both air-water and oil-water interfaces.
Journal ArticleDOI
Enhanced foam stability by adding comb polymer gel for in-depth profile control in high temperature reservoirs
TL;DR: In this paper, a long-term stability of gel enhanced foam as an in-depth profile control agent in high temperature reservoirs was successfully prepared by adding comb polymer gel, which can enhance the thickness and strength of foam film.
Journal ArticleDOI
Experimental study and application of gels formed by nonionic polyacrylamide and phenolic resin for in-depth profile control
TL;DR: In this paper, a phenolic resin cross-linked nonionic polyacrylamide (NPAM) gel used for in-depth profile control was systematically analyzed and a compact three-dimensional network structure was formed in the bulk gel system and in porous media.
Journal ArticleDOI
Preparation and application of a novel phenolic resin dispersed particle gel for in-depth profile control in low permeability reservoirs
TL;DR: In this article, the effects of bulk gel strength, shearing time and bulk gel-water mixing ratio on the prepared phenolic resin dispersed particle gel (PDPG) particles were systematically analyzed.
Journal ArticleDOI
New insights into the hydroquinone (HQ)–hexamethylenetetramine (HMTA) gel system for water shut-off treatment in high temperature reservoirs
TL;DR: In this paper, the performance and effects of various parameters were systematically evaluated and the gelation mechanism was proposed, illuminating the detailed gelation process clearly, and the thermal stability measurement indicates that the gel can maintain stability up to 140°C.
