Abstract

Liquid loading in gas wells is one of the main causes of production decline, and, if not diagnosed in time, can cease the wells. The phenomenon is influenced by various factors, such as hydrodynamic parameters, flow regime, well trajectory, properties of reservoir fluids or production rates during operation [1]. Accurate assessment of the impact of each factor in specific conditions is critical to find solutions to restore the well and bring back the production flow.

In the paper, the authors analysed to determine the cause of water column appearance, applied a combined calculation technique to deliver a technological solution and construction design for a platform that is limited in structure, load and operating space. The solution has been successfully applied to production well TB-1P, Thai Binh gas field, offshore Vietnam.
