Operation of Gas and Gas Condensate Wells at the Final Stage of Field Development

Abstract

The article considers the problems, arising during the operation of gas and gas-condensate wells at the final stage of field development. The primary focus is on the intermittent operation of gas and gas-condensate wells. The operation of those wells is characterized by the complexity of hydrocarbons production and fulfilling output targets. The authors propose to automate the intermittent well operation by installing well control facilities at the wellhead. The facilities will control the well start-up or shut-down in case of increase or drop in the flowing tubing pressure
respectively. This measure will be efficient for several wells that are intermittently operated and connected to gas treatment facility by means of one line, as there are difficulties in handling them. It is recommended to install the pressure and temperature sensors at the wellhead and gas treatment facilities for the continuous monitoring of well operation parameters. The implementation of the proposals will help to control well performance and choose the optimal well operation modes. The installation of the facilities will help to improve the efficiency of the intermittent operation of the wells, connected to one line, and at different operating parameters. The practical use of the above mentioned technical solutions will contribute to the most efficient intermittent operation of wells.
