... such treatments still represents a dilemma for conformance experts due to the lack of systematic design tools in the industry. This paper proposes and makes available a new design approach for bulk gel treatments by grouping designs of 62 worldwide field projects (1985-2018) according to gel volume-concentration...

... Abstract Polymer bulk gels have been widely applied to mitigate excessive water production in mature oil fields by correcting reservoir permeability heterogeneity. This paper presents a comprehensive review of the water responses and the economic assessments of injection-well gel treatments...

... Abstract Assessment of the potential of polymer flooding and gel treatment to investigate their roles of improving sweep efficiency requires an accurate modeling of polymer rheology (polymer viscosity versus shear rate) coupled with the effects of water salinity. A 3-D simulation model...

... Abstract In-depth gel treatment has become an attractive and optimum technology for remedying any problems that cause poor sweep efficiency, such as heterogeneity of the reservoir and unfavorable mobility ratio (due to high oil viscosity). The low recovery factor resulted from the difference...

... treatment, the month after the gel treatment, and the month after the acid treatment. In every well treated, the water rate was greatly reduced but the oil rates were reduced as well. In three of the four wells treated with acid, the oil rate exceeded pre-gel levels. The operator tried several times...

..., requirements that must be met in candidate wells and well patterns in order to achieve success, gel treatment elements that must be successfully implemented in order to achieve success, guidelines where conformance polymer-gel treatments are most successfully applied, risks and pitfalls of gel conformance...
