DRILLING TECHNOLOGY FOR DUAL COMPLETION OF WELLS

The monograph fully considers such tasks as the simultaneous development of several reservoirs using technologies and uninterrupted regulation of the ability of oil and gas recovery of reservoirs due to pressure differences during simultaneous operation, separate identification of the productivity properties of each reservoir using newly created equipment. The research is based on drilling materials and various developments at the multi-layer field of Turkmenistan at abnormally high reservoir pressure, by design separately for each well and a complex consisting of various packers, circulation and gas lift valves and other auxiliary downhole equipment installed on a two-lift tubing dual completion (DC) development by the gas lift-fountain method of three large horizons (in as part of their 9 layers) tested on 4 wells.The monograph can be useful to process engineers of drilling and oil and gas producing enterprises, specialists involved in drilling and development of oil and gas fields, graduate students and university students studying in the oil and gas field.
