n: A kind of wash over fishing tool. The slip grip which is used to wash over and fish the pipe stick in the wellbore is installed in the washover pipe.

chemicals which prevent hydrate crystals from sticking together and forming a larger mass.

n: This schlumberger module provides direct measurements of wellbore fluid resistivity and temperature, also cable tension below the toolstring head. Useful to run in poor hole condition;should allow differentiation of differential sticking and keyseat stic

n: pressure produced parallel with the cylinder axis when casing hits a deviation in the hole or a sticky spot and stops. The force pushing down on the pipe causes axial compression.

n: A kind of explosive package used for breakouting pack of dynamic. It is sent by cable to first thread above the sticking point. Pull the drill stem and rotate left the

n: The operation that joins the driving stem to pick up drill stem and circulate the drilling fluid when touch sticking

v: 1. to collect a mass of sticky consolidated material, usually drill cuttings, on drill pipe, drill collars, bits, and so forth. A bit with such material attached to it is called a balled-up bit. Balling up is frequently the result of inadequate pump pressure or insufficient drilling fluid. 2. in reference to an anchor, to fail to hold on a soft bottom, pulling out, instead, with a large ball of mud attached.
