n: Schlumberger wireline tool that measures deep and shallow formation resistivity. Used to deduce true resistivity Rt, flushed zone resistivity, invasion profiles, quicklook Hydrocarbon detection and indication of moved Hydrocarbons.

n: the area near the wellbore where invading mud filtrate forces out the movable formation fluids. Often abbreviated Rxo

part of the rock that has been flushed with a sweep fluid. The area may have little hydrocarbons remaining.

n: trade name for focused electric log that investigates the flushed zone.

n: an area within a permeable rock adjacent to a wellbore into which a filtrate (usually water) from the drilling mud has passed, with consequent partial or total displacement of the fluids originally present in the zone.

n: The volume close to the borehole wall in which some or all of the moveable fluids have been displaced by mud filtrate. It consists of the flushed zone and the transition zone or annulus. In simple models, the invaded zone and the flushed zone are consider

the part of the rock next to the wellbore into which wellbore fluid has leaked.

n: a guard-electrode log that measures the resistivity of the flushed zone.

a pad contact micro resistivity log. Useful for assessing the flushed zone fluid in contact with the pad.

n: a proprietary name for a logging tool that measures resistivity of the flushed zone of the formation adjacent to the wellbore.

shallow formation reistivity, usually of the flushed zone, from a very shallow reading device.

spherically focused resistivity log. Measures the resistivity of the flushed zone (Rxo). In a hydrocarbon zone, the curve may report higher resistivity than deep (ILD) or medium (ILM) induction curves because the flushed zone contains mud filtrate and res

water saturation of the flushed zone.
