A service rig is a mobile platform loaded with oil industry service equipment that can be driven long distances within the oil fields to service wells. [1] [2] Unlike drilling rigs, service rigs return to a particular well many times.
Casing head (#27) is a large metal flange welded or screwed onto the top of the conductor pipe (also known as drive-pipe) or the casing and is used to bolt the surface equipment such as the blowout preventers (for well drilling) or the Christmas tree (oil well) (for well production).
Larger rigs are capable of drilling through thousands of metres of the Earth's crust, using large "mud pumps" to circulate drilling fluid (slurry) through the bit and up the casing annulus, for cooling and removing the "cuttings" while a well is drilled. Hoists in the rig, a derrick, can lift hundreds of tons of pipe.
May 10—The Occidental Petroleum Co.'s first quarter highlights included the first-of-its-kind deployment of a fully electric well service rig in the Permian Basin. Oxy President-CEO Vicki Hollub ...
With high-performance jackup rig rates in 2015 of around $177,000, [25] and similar service costs, a high pressure, high-temperature well of duration 100 days can cost about US$30 million. Onshore wells can be considerably cheaper, particularly if the field is at a shallow depth, where costs range from less than $4.9 million to $8.3 million ...
225k Snubbing Unit 340k units are designed to perform live and dead well interventions on both land & offshore. Snubbing is a type of heavy well intervention performed on oil and gas wells. It involves running the BHA on a pipe string using a hydraulic workover rig.
