RESIN COATED PROPPANTS AND PROCESS FOR THE PREPARATION THEREOF

摘要

Highly spherical proppants of sizes 12/20 and 20140 US mesh have been prepared from ground bauxite samples having different alumina content of particle size around 50 micron. Proppants are sintered at a temperature range 1350 - 1450 O C and are then coated with resol type phenolic resin..Coating is done without using any coupling or partitioning agent. The resin coated proppants show improved results towards acid solubility (in 3% HF-12% HCI mixture) and crush resistance (upto 15000 psi) as per API specifications.
