Shut In Tubing Head Pressure - Industrial Professionals ...

2014-1-3 · Posted 03 January 2014 - 06:13 AM. As Ervin has replied rightly, Shut-in Tubing Head Pressure is the pressure of well head tubing when well is in shut-in condition, i.e there is no flow across the choke. STHP can be calculated by knowing the reservoir pressure, reservoir depth, fuild compostion and length of the well tubing.

6.2: Introduction to Gas and Liquid Flow through Well

It is the bubble-point pressure along the dashed path that results in the onset of the bubble flow pattern shown in Table 6.01. As flow continues up the tubing in Table 6.01, the pressure continues to fall causing gas bubbles to expand due to the compressible nature of gas and solution gas to come out of solution. As the gas bubbles expand ...

Removing the equipment can cost between $5,000 and $50,000 depending on what’s downhole and what machinery is needed to remove it (workover rig vs. rigless, for example).

In oil and gas production, Tubing is the pipe or conduit where fluids are transported from the reservoir to the surface. This is shown Figure 6.01.Figure 6.01 shows the Wellbore Schematic for a typical vertical well. This figure is a schematic cross-section through the axis of the well. This schematic shows two types of pipe, casing and tubing.
