v: to move a rig with a standard derrick from the location of a lost or completed hole preparatory to starting a new hole. Skidding the rig allows the move to be accomplished with little or no dismantling of equipment.

n: The work of transporting the total rig and derrick equipment to a new well, usually dont need to detact the equipment.

v: seperating the rig to several group,which can decrease the time of delivery and cutting cost.

n: an earthen pit. often lined with concrete or other material, into which water with small amounts of oil is pumped. The minute quantities of oil are skimmed off the top of the water in the pit. and the water is disposed of.

n: a special tank into which water with small quantities of oil is piped. When the oil rises to the top, blades on a skimmer direct the oil into a discharge line.

n: a piece of equipment in a glycol dehydration unit that performs the same function as a separator;however, it cannot handle as much gas and condensate as a separate unit. See separator.

n: 1. the area of the formation that is damaged because of the invasion of foreign substances into the exposed section of the formation adjacent to the wellbore during drilling and completion. 2. the pressure drop from the outer limits of drainage to the wellbore caused by the relatively thin veneer (or skin) of the affected formation. Skin is expressed in dimensionless units: a positive value denotes formation damage;a negative value indicates improvement. Also called skin effect.

a dimensionless estimation of obstruction to flow. An undamaged well would have a skin of zero. A damaged well has a positive skin above zero and a stimulated well has a negative skin.

n: 1. The loss in amplitude and change in phase of an electromagnetic field as it penetrates into a conductive medium. In an induction log, the skin effect causes a reduction of the R-signal (in-phase) and an increase in the X-signal (out-of-phase) at the re

a fracture treatment designed to bypass skin damage.

n: a mast on a well servicing unit that utilizes a split traveling block and crown block, which makes it possible to pull 6O-foot (18.3-metre) stands with a 50-foot (15.2-metre) mast.
