The Benefits of the Thru-tubing Sand Control

Problems connected to the sand control in completed production wells usually result because of wrong primary completion design. Marginal wells that are producing sand and have poor reserves do not support the cost of a major workover program. In such areas it is not economical to re-complete the well by the use of classical tubing and packer system and standard completion rigs. Some remedial works include sand bailing with wire line (obsolite, time consuming, small volumes) and sand washing with coiled tubing. Unfortunately such services are only a temporarily solution and do not solve the problem of sand production. Today there are a number of products and services available to the industry which increases the success of thru-tubing sand control. Thorough planning and training have arisen as the primary solution of the sand control problems.
