Lag Time In Drilling | Actual & Calculations

A definite time interval is always required for pumping the samples from a particular depth to the surface where they can be collected. When determined, This critical time interval is called “Drilling lag time” and can be measured in terms of pump strokes and time. This lag applies to all downhole information, including formation cuttings …

Drill Bit Pressure Drop & Hydraulics Calculators

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 significant percentage of normal circulating pressures is lost by pumping through the nozzles. The pressure loss is not frictional pressure but rather acceleration forces. Assumptions generally made are: 1) the …

Leak Off Test Procedures & Calculations Sheet

Before starting leak off test drilling procedures, gauges should be checked for accuracy. Also, the upper-pressure limit should be determined. It is so simple to run leak off test drilling but if you exceeded certain pressure, you may break the formation and a loss of circulation may occur. Leak Off Test Best Practice Pre-job Procedures. …
