Method of using shaped compressed pellets in treating a well

摘要

Shaped particulates which have been compressed from a composite of a well treatment agent and adsorbent in a matrix may be introduced into horizontal or deviated oil or gas wells. The well treatment agent of the shaped pellets may be used to prevent and/or control the formation of deposits in a production well.

1. A method of inhibiting or controlling the rate of release of a well treatment agent in a well during production of fluids from the well, the method comprising:
(a) introducing into the well a shaped pellet produced by compressing a mixture into a desired shape, the mixture comprising a (i) binder and (ii) a composite of a well treatment agent adsorbed onto a water-insoluble adsorbent wherein the surface area of the adsorbent of the well treating composite is between from about 1 m2/g to about 100 m2/g and wherein the binder holds the composite together during compression of the mixture; and (b) releasing the adsorbed well treatment agent from the composite into produced fluids within the well.
