n: the process of tracking down the source of an illegal waste discharge through sampling the waste and possible sources to determine which source matches the discharge best. Fingerprinting is expensive, but in large damage cases, it can help prove or disprove whether a substance was discharged from a particular source.

n: (GIN) a number issued to any person, by site, whose act or process produces hazardous waste. Such a number is required by the EPA under the Resource Conservation and Liability Act of 1976 for the purpose of tracking hazardous waste.

a method of tracking a fracture by listening for the sounds of shear fracturing in the formation during the hydraulic fracturing process.

n: a downhole tool with rough, sharp, extremely hard cutting surfaces for removing metal, packers. cement, sand, or scale by grinding or cutting. Mills are run on drill pipe or tubing to grind up debris in the hole, remove stuck portions of drill stem or sections of casing for sidetracking, and ream out tight spots in the casing. They are also called junk mills. reaming mills. and so forth, depending on their use. v: to use a mill to cut or grind metal objects that must be removed from a well.

n: a downhole tool with rough,sharp cutting surfaces for removing metal by grinding or cutting.

a cutting tool used to grind up metal, dress off a fish, or open up a window for a kick-off.

applying a washable or non-washable radioactive tracer to equipment or proppant to allow tracking of position of the tagged item in the well. Can be used to determine if radioactive tagged sand entered the formation at a specific set of perforations.

n: a bit especially designed for use in drilling a hole around an obstruction in the main borehole. Usually, a cement plug is set on top of the obstruction, the side tracking bit is run into the hole on a whipstock or other directional drilling device, and the new borehole begun. Because the new borehole goes off to the side of the plugged borehole, the operation is called side tracking.

n: a kinds of diamond bit that drills directional well or a new wellbore.

n: The processing of cutting window on the casing ,which used in side tracking in the well that have runned casing .

n: a rare type of bit-tooth wearoccurring when the pattern made on the bot- tom of the hole by all three cones of a rock bit matches the bit-tooth pattern to such an extent that the bit follows the groove or channel of the pattern and drills ahead very little.

n: The summit and trace of tooth on the surface of bottom hole in cone bit drilling.
