n: Usually refers to the operation that ogging device measures deviation angle and azimuth. There are two types: single-shot survey and multimetering.

n: a tool that, when lowered into the wellbore, makes a photographic record of the angle and drift of the wellbore;that is, it records the number of degrees the hole is off vertical and the direction in which it is off vertical. Several types of instrument are available;some are capable of photographing only a single record - single-shot survey instrumentswhereas others are capable of making several records in one run - multishot survey instruments.

n: 1. a charge of high explosive, usually nitroglycerine, detonated in a well to shatter the formation and expedite the recovery of oil. Shooting has been almost completely replaced by formation fracturing and acid treatments. 2. a point at which a photograph is made in a single-shot survey. See directional survey.

n: a directional survey that provides a single record of the drift direction and off-vertical orientation of the hole. See directional survey.

n: A technique for acquiring deviation information from a borehole on a slickline. In high-angle wells, a multishot technique is usually used instead.
