Abstract
In oil and gas wells, excessive water production is a major concern in the production of hydrocarbons. Chemical treatments are technologies widely used for solving water control problems and among them the injection of gels in the water producing zone is nowadays a mature technology. In this work we evaluated, by means both of oscillatory measurements (oscillatory measurements at low amplitude) and indentention test, the gelation time (Winter & Chambon criteria) and the gel stability of two different kind of commercial gels, an organic (polymer based) and an inorganic (silicate based) typically used in field applications.
A correlation between rheological measurements and standard laboratory tests (such as observing the sol-gel transition checking the viscosity and/or the turbidity of the sample in the oven at reservoir temperature) were proposed. All these results helped us in the data interpretation of coreflood experiments used to design field applications.

The Italian Society of Rheology (SIR) organizes every two years the Italian Rheology Conference, which is the meeting point of the National and International rheological community to promote knowledge and discuss research in the field of rheology. The Conference consists of keynote lectures, oral communications and posters on topics related to all the thematic areas of rheology. The XIX edition will be held in the conference rooms of Plesso Belmeloro, in the city centre of Bologna, in June 16th-19th, 2026. Book your accommodation in Bologna well in advance, the city is a famous tourist destination and has limited availability of accommodations!
