depth of invasion

Oil & gas; Oilfield

The distance from the borehole wall that the mud filtrate has penetrated into the formation. The depth of invasion affects whether a log measures the invaded zone, the undisturbed zone or part of ...

diameter of invasion

Oil & gas; Oilfield

The distance from the borehole wall into the formation that the mud filtrate has penetrated. The term assumes equal invasion on all sides of the borehole. It is the diameter of the circle thus ...

Euclidian distance

Oil & gas; Oilfield

The distance between two points in Euclidian space. Euclidian dimensions are all orthogonal to each other (they are all at right angles to each other) and refer to physical space.

The distance between the external surface of the gun assembly and the internal surface of the casing or liner. The gun clearance depends on the position of the gun within the tubular and will vary ...

pressure drawdown

Oil & gas; Oilfield

The differential pressure that drives fluids from the reservoir into the wellbore. The drawdown, and therefore the production rate, of a producing interval is typically controlled by surface chokes. ...

pump submergence

Oil & gas; Oilfield

The difference in hydrostatic head between the pump depth and the dynamic fluid level above the pump. The pump submergence is continuously monitored to adjust the pump flow rate and avoid a pump-off ...
