differences in rock – segments showing different responses when measured.

n: any shipboard tank or tanker compartment normally used for carrying saltwater ballast. When these compartments or tanks are not connected with the cargo system, they are called segregated ballast tanks or systems.

a segment of geoscience where fossils are used to date or identify a reservoir.

the specific gravity of the unset cement slurry as mixed at the surface. Does not account for water loss to leakoff or segregation before the cement sets.

n pi: special segmented weights attached to the guy wires of a guyed compliant platform that keep the guy wires taut as the platform jacket moves with the waves and current of the water. As tension on a guy wire is lessened, one or more segments of the weight drop to the seafloor and re-establish tension on the wire. As tension increases on a guy wire, the tension pulls one or more segments off the seafloor so that the wire is not over stressed.

a mechanical device used for holding or locking where segmented keys or fingers are pushed into a recess to hold, anchor or grasp the tool.

segregated flow units of a main reservoir that have a poor flow connection or no flow connection to the main reservoir.

n: a single well that produces from two separate formations at the same time. Production from each zone is segregated by running two tubing strings with packers inside the single string of production casing, or by ruunign one tubing string with a packer through one zone while the other is produced through the annulus. In a miniaturised dual completion, two separate 4.5-inch (11.4-centimetre) or smaller casing strings are run and cemented in the same wellbore.

n: a completion method in which two hydrocarbon reservoirs with different pressure in the same well



two pay zones in the same well that produce up independent flow paths in the same well.

n: refer to extra long casing slip
