Learn how the right proppant can reduce short-term workover expense

When your goal is to minimize operating expenses caused by sand and proppant flowing back, investing in curable resin-coated sand is an excellent insurance policy. Curable resin-coated sand, a type of proppant, is widely recognized for its ability to set and create a bonded network that locks into fractures, preventing proppant flowback and maintaining high conductivity to facilitate strong production. Using a proppant to prevent proppant flowback is the most straightforward approach to solving the problem; you can stop it before it ever starts.

Reports from five E&P companies conclude that 10 to 15% of wells experience proppant flowback in the first two years of operation. In a typical horizontal well, mitigation costs can easily fall in the range of $280,000 to $515,000 (see table at right). Plus, any examination of workover costs should also factor in the cost of lost production during repair operations.
