The well control equations in this ebooks are as follows;

• Pressure (P)
• Pressure Gradient (G)
• Hydrostatic Pressure (HP)
• Bottom Hole Pressure (BHP)
• Under static condition
• Under dynamic condition
• Formation Pressure (FP)
• Equivalent Circulating Density (ECD)
• Leak-off Test Equivalent Mud Weight (LOT)
• Maximum Initial Shut-In Casing Pressure (MISICP)
• Kill Mud Weight to Balance Formation (KMW)
• Slow Circulation Rate (SCR)
• Annulus Capacity Factor (ACF)
• Final Circulating Pressure (FCP)
• Surface To Bit Strokes
• Circulating Time
• Capacity Factor (CF)
• Opened End Pipe Displacement
• Closed end pipe displacement
• Height of Influx
• Approximate gas migration rate
• Sacks of Barite Required For Weight-up
• Volume Gain From Slug
• Triplex Pump Output (volume)
• Pump Output
• New Pump Pressure With New Pump Strokes
• Boyle’s Law – Gas Pressure and Volume Relationship
• Mud Increment for Volumetric Method (MI)
• Lube Increment for Lubricate and Bleed Method (LI)
• Bottle Capacity Require
• Volume of Usable Fluid
• Snubbing force for snubbing operation
• Buoyed Weight of Open Ended Tubular (Wb)
• Buoyed Weight of Closed Ended Tubular without fluid in the pipe (Wb)
• Buoyed Weight of Closed Ended Tubular after filling the pipe (Wb),lb -> in this case, there is different fluid weight in pipe and annular
• The Balance Point for closed ended and unfilled pipe is the point where the weight of pipe in the fluid equates to force created by wellhead pressure.
• This is the second case for balance point calculation. The Balance Point for closed ended pipe and the pipe is filled with fluid.
• Maximum Down Force on Jacks
