ECD / Equivalent Circulating Density is an important parameter to monitor in the drilling process of a well, especially in horizontal & HPHT wells. In
Calculation of both hydraulic horsepower and impact force mainly depends on calculating pressure drop across the bit. A major percentage of normal circulating pressures is
For many years, drilling engineers have known that hydraulics play an essential role in cleaning the face of the formation so that a bit can
Introduction To Drilling Hydraulics Calculations Drill Bit Pressure Drop Calculation Calculation of both hydraulic horsepower and impact force are mainly depend on calculating pressure drop
This article will handle the definition of the term Total Flow Area, how to calculate TFA, how to use the TFA chart to calculate bit
Chapter II Stand Pipe Pressure Or Pressure Loss (Friction Pressure) Calculations Pumping a drilling fluid requires overcoming frictional drag forces from fluid layers and solids
Chaper I Drilling Mud Flow Regimes Flow Regimes are the behavior of the fluid while flowing in a well. The most common regimes are laminar,
Why It Is Important To Understand Drilling Hydraulics? The drilling hydraulics system serves many purposes in the well. Since it is centered around the drilling
Surging or swabbing pressures in drilling describe pressure changes in the annulus resulting from pipe movement. The swabbing occurs when the drill pipe is pulled
