How to Achieve the Lowest Possible Reservoir Pressure to Maximize Gas Recovery
By Kees Veeken (NAM Production Technologist)
Most gas reservoirs in The Netherlands behave as tanks which means that their pressure continuously declines, as gas is being produced to surface. The declining reservoir pressure results in a diminishing gas production rate up these gas wells. At some stage, the gas rate becomes insufficient to lift the free liquids (water and condensate), which are inevitably associated with gas production, to the surface. As a result, those liquids accumulate inside the gas well. This process is called liquid loading and will stifle and eventually kill gas production. Techniques have been developed to prevent liquid loading and extend production. These techniques are called liquid unloading or gas well deliquification measures, and cover a wide range of techniques ranging from surface compression to injecting surfactant to pumping liquid to surface.
In this presentation, the liquid loading process, the gas well deliquification techniques and the impact on gas production and gas recovery are explained and illustrated for NAM (Nederlanse Aardolie Maatschappij) operated gas fields.
