n: Completion with oil tube instead of casing in slim hole. The hydrocarbon flow is produced from oil tube. This completion program is suitable for the well with shallow oil zone and low produce.

n: An inexact term describing a borehole (and associated casing program) significantly smaller than a standard approach, commonly a wellbore less than 6 in. in diameter. The slimhole concept has its roots in the observed correlation between well costs and vo

a smaller well. Thought to be cheaper to drill, but much more expensive to repair or workover and often limited on fluid flow rate potential.

n: A telescoping joint at the surface in floating offshore operations that permits vessel heave (vertical motion) while maintaining a riser pipe to the seafloor. As the vessel heaves, the slip joint telescopes in or out by the same amount so that the riser b

n: drilling in which the size of the hole is smaller than the conventional hole diameter for a given depth. This decrease in hole size enables the operator to run smaller casing, thereby lessening the cost of completion. See miniaturized completion.

n: by current industry definition, is one where the well is TDd in 4 1/2 or smaller hole size. Slim hole drilling brings significant cost and enviromental benefits but makes well control more diffcult due to the high ECDs and small annular capacities.
