It will be recalled that the upward velocity of the mud in the annulus between the drill pipe and wall of the hole is an

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
Drill Bit Pressure Drop Calculation Calculating hydraulic horsepower and impact force depends on calculating pressure drop across the bit. When jet bits are used, a
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
Pumping a drilling fluid requires overcoming frictional drag forces from fluid layers and solids particles. In this article, we will explain the pressure loss calculation
Flow Regimes are the behavior of the fluid while flowing in a well. The most common regimes are laminar, turbulent, and transitional. Unfortunately, it is
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
