The use of airlift during drilling of technological wells

Abstract: The article describes new drilling methods recognized as testing works in the drilling company “Volkovgeologiya” JSC. A special feature of this method of drilling is the introduction of the airlift principle. The proposed technology differs in that it is applicable during well drilling and does not require investments for reconstruction, which is significantly reflected in the number of repair and restoration works. With a wide application of this method, the possibility of providing a huge economic effect in … Show more
