Definition - What does Snubbing Unit mean? A Stubbing Unit is a hydraulically actuated unit that contains slips, hydraulic jack and blowout preventer stack for pulling or inserting bottomhole assembly and tubing from a live or an under-balanced well state.

A drill bit is what actually cuts into the rock when drilling an oil or gas well. Located at the tip of the drillstring, the drill bit is a rotating apparatus that usually consists of two or three cones made up of the hardest of materials.

Short stroke modular construction diesel powered hydraulic snubbing system. The function of this system is to service pressured wells up to 10,000 psi (69 MP2) without having to kill the well. This system is designed for use onshore or offshore in environments with ambient temperature ranges of -40ºF to 130ºF.

Petropedia explains Snubbing Unit. A Snubbing Unit came into existence in the 1920's when the necessity for rigs to work under pressure was felt. The first unit was designed to work in well control situations to snub casing or drill pipes out of or into the wellbore. The unit was used when conventional methods of well killing did not work.

Equalize spool: A ported spool for use in a snubbing operations allowing the operator the ability to equalize or bleed off certain sections of the BOP stack. Gas well snubbing: Workover or completion work on a gas well which is either live or underbalanced with a rig assist or self contained snubbing unit. Many gas well formations are fluid sensitive making a snubbing operation ideal for maximum production of the well. Eliminates the need for expensive kill fluids.

How Snubbing Units Work. History of Snubbing Units. Snubbing units have evolved into one of the most capable and efficient well servicing tools in the oil & gas industry. In the 1920’s, the need for a rig to work with pressures at surface drove the invention of the snubbing unit.

Hydraulic Workover/Snubbing. Halliburton’s hydraulic workover (HWO)/snubbing technologies. provide a flexible and cost-effective alternative to conventional. drilling and workover rigs whether it’s for drilling, work over. or completing a well. Ideally suited for the most technically. demanding operations, including HPHT, both onshore and. offshore, our HWO/snubbing units and associated technologies.

Directional drilling has been an integral part of the oil and gas industry since the 1920s. While the technology has improved over the years, the concept of directional drilling remains the same: drilling wells at multiple angles, not just vertically.

Because heavy oil is so viscous, conventional methods, such as vertical wells, pumps, and pressure maintenance, are inefficient at extracting the oil. So, new technologies are being used to recover heavy oil including: cold heavy oil production with sand (CHOPS), vapor extraction (VAPEX), and thermal in situ methods.
