Shut In Tubing Pressure

This pressure (which is usually in the thousands of psigs) is termed the "shut in tubing pressure" and is very important in knowing and identifying what it will be in order to design the Christmas Tree and most of the downstream treating equipment. Let me give you an example:

Tubing changes from pressure and temperature

 · Changing the mode of a well (producer, injector, shut-in, or treating) causes changes in temperature and pressure inside and outside the tubing. This can create length and force changes in the tubing string that can potentially affect the packer and downhole tools.

The blowout preventers are the principal piece of equipment in the well control system and are operated hydraulically; pressurized fluids are used to operate pistons and cylinders to open or close the valves on the BOP. The Accumulators (Item 18 in Figure 9.02) are used to store pressurized, non-explosive gas and pressurized hydraulic fluid to run the hydraulics systems on the rig.

pressure integrity test | Oilfield Glossary

During the test, the well is shut in and fluid is pumped into the wellbore to gradually increase the pressure that the formation experiences. At some pressure, fluid will enter the formation, or leak off, either moving through permeable paths in the rock or by creating a space by fracturing the rock.

Pressure Decline

The pressure decline during shut-in is affected by the total amount of energy (the product of net pressure and fracture volume at shut-in) stored in the fracture and the rate of fluid loss. The pressure decline analysis is based on the assumption that the change in the fracture volume is entirely contributed by the change in the average fracture width throughout the shut-in period.

Shut-in procedures for well control

 · When one or more warning signs of kicks are observed, steps should be taken to shut in the well. If there is any doubt that the well is flowing, shut it in and check the pressures. It is important to remember that there is no difference between a small-flow well and a full-flowing well, because both can very quickly turn into a big blowout.

Shut In Tubing Head Pressure

The flowing wellhead pressure is usually much lower, due to the friction loss of the well fluids coming up the tubing and also the gravity head of the well fluids. When the well is shut in, the liquid content of the tubing can drain back down, resulting in a lower static head above the reservoir and thus a higher pressure at the top.
