n: A group of pipe or other pipe lean on the pipe finger of derrick.

a composite of traces from different seismic records.

v: to store a drilling rig on completion of a job when the rig is to be withdrawn from operation for a time.

n: a primary cementing operation in which cement is pumped into the well in a series of operations or stages. stage separation n: an operation in which well fluids under pressure are separated into liquid and gaseous components by being passed consecutively through two or more separators. The operating pressure of each succeeding separator is lower than the one preceding it. Stage separation is an efficient process in that a high percentage of the light ends of the fluid are conserved.

n: Seperating the cementing work into two sections or multisections work.

n: The special collar used in stage cementing .

n: a special tool used in stage cementing.

a alternate path device that allows access into the annulus when shifted. Used in two stage cementing operations to pump the upper job.

sequenced cement jobs that are placed through different entry points into the annulus. Undertaken to place a higher cement column in the annulus when the fracturing gradient of the exposed formations will not tolerate a full column of cement.

n: The ratio of the screw-liner movement pair to liners motion.
