Tubing Joints for Running Independent Strings in Dual Wells

Presenters

J.B. Gillham, Hydril Company

The purpose of this paper is to outline the types of tubing joints and combinations of tubing that are considered satisfactory for use in dual wells, completed with two or more independently hung tubing strings. Field experience in running two or more independent strings of tubing has indicated certain running clearance requirements. The clearance can be calculated for the various dual well conditions. Many of these combinations are shown on clearance charts. The use of two or more tubing strings in dual wells appears to offer many advantages for rod pumping, hydraulic and for gas lift systems or combinations of any two of these methods.
