As a solution to the presented problem, in this paper, it is proposed to use gas-jet devices (GJD) to reduce the wellhead pressure of wells, which allows to jointly operate high-pressure and low-pressure wells...

... pressure below the wellhead even for a few seconds resulted in instantaneous water ingress into gas pipeline. In addition, when using a tee, it was not possible to obtain a dispersed-bubble flow regime. Even at high wellhead pressures (up to 6.2 MPa), the WGM flow regime was exfoliated. To ensure...

Well XX-d was tested 3 times individually at 2016: in March, in May and in August ( Figure 13 ). As it can be observed, there is insignificant difference between values of oil rate and wellhead pressure, due...
