v: to obtain a core from the bottom of an existing well by using a core bit. See core (defn. I),core bit.

n: Drilling for core with coring tool in order to obtain geologic information.

n: see critical point, defn. 1.

a wireline or tubing run into a well with a dummy piece of equipment of the same size, shape and stiffness of a valuable or unrecoverable piece of equipment to make sure the equipment can be placed.

fishing neck.

n: a person who conveys property. COfnpaIe grantee.

lay down for night.

n: The structure used to support the crown blocks and the drillstring. Masts are usually rectangular or trapezoidal in shape and offer a very good stiffness, important to land rigs whose mast is laid down when the rig is moved. They suffer from being heavier

n: the maximum stiffness of make up of string.

n: the ratio of the increment of some specified form of stress to the increment of some specified form of strain, such as bulk modulus, shear modulus, or Youngs modulus. Also called coefficient of elasticity. elasticity modulus, elastic modulus.

stress over strain. A measure of stiffness or Young’s Modulus (E). Rocks are ½ to 12 x 106 psi and mild steel is 30 x 106 psi. Modulus refers to stress at a predetermined level of elongation, usually at 100% elongation. The higher the modulus of a compoun

n: according to some mineral stiffness to decide the line.

a ten point scale of mineral hardness. The levels are keyed to the minerals: talc, gypsum, calcite, fluorite, apatite, orthoclase, quartz, topaz, corundum, and diamond.
