Infographics - How to develop Incentive

PVT, ESP, TWCV, BPV

PVT Sensor - Pit Volume Sensor
Sensor that measures whethere there is an influg or loss from the mud system.
There are 2 sensors that must be there all times to notify the Driller about well condition:

1. PVT
2. Flow Line Flap valve - on the flow line from BOP that tells how much flui is flowing out of the well

 

ESP - Electrical Submersible Pump
Pump hanging on the tubing down hole that pumps the oil from reservior through the turing up to the surface.

 

TWCV - Two Way Check Valve

BPV - Back Pressure Valve

These are 2 types of the valves in the tubing hanger. TWCV - Check valve though which you still can pump in. Whereas BPV doesnt allow any operation, it holds pressure down to make the operations on top safer.

There always must be 2 barriers between the formation fluid and surface in production wells . And these barriers must be independent from each other.

Inside the tubing:

• Plug
• TWCV / BPV

 

In Annulus:

• Packer
• Tubing Hanger
