Title
(EN) COATED PROPPANTS
(FR) AGENTS DE SOUTÈNEMENT ENROBÉS
Abstract
(EN)
Coated proppant particles are prepared from a coating composition that includes at least one polyisocyanate and an isocyanate trimerization catalyst. The coating composition preferably is devoid of an effective amount of a urethane, urea and carbodiimide catalyst. The coating composition cures rapidly at moderate temperatures, and bonds to itself well under conditions of heat and pressure as are experienced by the particles in subterranean formations.
(FR)
L'invention concerne des particules d'agent de soutènement enrobées qui sont préparées à partir d'une composition d'enrobage qui comprend au moins un polyisocyanate et un catalyseur de trimérisation d'isocyanates. La composition d'enrobage est de préférence dépourvue d'une quantité efficace d'un catalyseur d'uréthane, d'urée et de carbodiimide. La composition d'enrobage durcit rapidement à des températures modérées et se lie bien à elle-même dans des conditions de chaleur et de pression telles que celles subies par les particules dans des formations souterraines.
