Sand production is one of the biggest problem in oil and gas production. Sand can damage the surface and downhole facilities. Sand production simply occurs in unconsolidated formation. To overcome this constraint, mechanical and chemical method has been much developed. In this research chemical method based on epoxy resin is used to solve sand production. Epoxy will react with its hardener to polymerize thus able to bind sand grain with covalent bond.

In this research, artificial core is synthesized to represent real core in oil and gas field. Those artifical core has 2:1 sand and cement ratio. It will be immerse into epoxy resin to evaluate its mechanical properties with and without resin treatment.

Data indicates that its compressive strength increase by test using uniaxial stress. However its porosity reduce 20-40%. From observation it is obvius to conclude that core immersing with resin will strengthen matrix binding among sand grains.. « Read the rest of this entry »
