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. This critical time interval, when definitely determined, is called “Drilling lag time” and can be measured in terms of pump strokes and in terms of time. This lag applies to all downhole information, including formation cuttings and the fluids (gas,oil and water) which they contain.
