One of the common things that Oil & Gas people will have to deal with all the time is Pressure, we are indicating to Oil Well Pressure here.
So...
What is Pressure ?
How do we measure it ?
Where we will deal with Pressure in Oil & Gas industry ?
Pressure is is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure is the pressure relative to the ambient pressure. Various units are used to express pressure.
We can measure Pressure easily using the following formula:
p = F / A
Where:
P is Pressure
F is Force
A is Area
There are many units for pressure but the most used one is PSI which indicates to Pound-force per square inch.
The pound per square inch or, more accurately, pound-force per square inch is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch. In SI units, 1 psi is approximately equal to 6895 N/m² (Newton Per Square Meter).
Once we start drilling Oil or Gas well we will have to deal with Pressure, let's count some of Pressures:
- Hydrostatic Pressure
- Formation Pressure
- Friction Pressure
- Pump Pressure
- Stand Pipe Pressure
- LOT or FIT Pressure ( leak-off test pressure, formation integrity test pressure)
- ICP (initial circulating pressure)
- FCP (final circulating pressure)
- Production Pressure...ETC
There are so many different types of Pressure that Oil & Gas people needs to know about, we will be explaining as much as we can more about Pressure.
