Application of high-tech installation Snubbing Unit

The first industrial revolution happened after the introduction of mechanization in production. The conveyor assembly became the symbol of the second one. The third was held under the slogan of shifting the center of value-added formation from production to sales and design. The fourth industrial Revolution is associated with rapidly developing technologies. Today we can confidently talk about technologies that will change the world in 5–10 years. The old paradigm of oil and gas field development systems, which prevailed over the past century, was based on maximizing the costs of their production processes. The new paradigm is a new concept of values, problem-setting models and their technical solutions aimed at the dynamic development and growth of the company’s capitalization in real time.

Purpose. The main technological challenge is to carry out work on wells with abnormally high reservoir pressure without jamming. Search for solutions to new approaches and breakthrough technologies in the field of routine and major well repairs.

Materials and methods. Now, various technological solutions have been tested and approaches to each type of wells have been identified that allow regulating the technological process. However, working with abnormally high reservoir pressures requires high-tech methods. Silencing of wells is the first preparatory stage before the start of the “life” cycle of a well or already in the production process before scheduled repairs, and one of the most expensive cost items in view of the features of the productive horizon — abnormally high reservoir pressures. In this article, the material on a promising mobile installation for repairing wells under pressure, without jamming, is proposed for consideration.

Results. The proposed method of well repair will reduce oil losses during the preparation of wells for cattle, prevent the destruction of the production column as a result of a long-term presence of a faulty well under pressure, reduce the cost of repairs, achieve the design displacement coverage factor by reducing the number of emergency fund wells in liquidation, as well as reduce the number of HSE (health and safety executive) incidents, reduce the risks of gas and oil production.

Conclusion. Thus, the new high-tech mobile installation Snubbing Unit will significantly reduce the cost of silencing wells and will take the current and major repairs of oil and gas wells to a new level.
