"The discovery of deeper production and higher pressures has resulted in the need for control equipment for preserving and protecting these great reservoirs of energy; and, in the case of high pressure condensate wells, has resulted in the need for means for preventing freezing or hydrate solidification caused by throttling the production. Development of a successful removable subsurface regulator has enabled operators to reduce dangerously high surface flowing pressures to safe workable limits; and, by moving the point of principal pressure reduction from the surface to warmer subsurface levels, has resulted in complete elimination of freezing conditions in flow lines. Development and operation of the regulator are described, and charts and tables for use in determining proper depths and pressure reductions for preventing freezing are shown. Other results, heretofore considered subordinate, such as reduction and stabilization of condensate ratios, and retarding of water encroachment, have been observed. Possibility of the use of subsurface regulators to establish conditions in the tubing string most favorable for condensate precipitations noted. Further technical research is desired relative to the use of subsurface regulators for controlling temperatures and pressures in the flow string to obtain conditions most conducive to condensate precipitation and an increased condensate recovery"--Abstract, pages 2-3.
