The tubing performance relation curve is a measure of well performance in gas well engineering. It describes the two-phase flow inside a well and as such is modeled as a two-phase one dimensional pipe flow. Convention claims that production points on the TPR curve to the right of its minimum are stable. There also exist claims about the region...

Natural gas wells produce small amount of liquids along with the gas. During the initial part of the reservoir life, the gas velocity in the well tubing is large enough to drag the liquid upwards. As the well matures, the reservoir pressure starts to decline leading to a decline in the gas velocity in the tubing; here the gas momentum is not...

The decline in productivity in mature gas fields is often attributed to liquid loading but in reality it may be a result of salt deposition which can have similar consequences. The phenomenon of salt precipitation is gradually increasing and is becoming a serious issue in the North Sea. The North Sea operators are aware of the serious...

Liquid loading is a major problem in the natural gas industry, in which gas production is limited by the accumulation of liquids in the well tubing. Liquid loading can be prevented by the injection of surfactants at the bottom of the well. The surfactants cause the liquid in the well to foam, thereby changing the gas-liquid flow in the well. The...

Up to now the well performance department within Total Exploration and Production Netherlands (TEPNL) base the assessment of well inflow performance on experiences in the field. No tools are available to systematically monitor and assess the reservoir-completion-tubing performance in the longer term (years). This makes that normal production...

In natural gas production, along with gas, a small amount of liquid is produced. Towards the end of a reservoir life, the gas velocity reduces due to a decline in pressure. A low gas velocity in a gas well causes undesirable liquid accumulation (loading) in the production tubing. One of the ways to postpone liquid loading is by injecting...
