Drilling Rig Components Show. Crown Block and Water Table. An assembly of sheaves or pulleys mounted on beams at the top of the derrick. The drilling line is run over the sheaves down to the hoisting drum. Catline Boom and Hoist Line. A structural framework erected near the top of the derrick for lifting material. Drilling
Blowout Preventers. Basic types of blowout preventers on drilling rig are: annular preventers ram preventers rotational preventers and diverters . components in natural rubber), is used with oil based muds or with muds that have oil based additives, and working temperatures from – 7 °C to 88 °C. Identification code is S or
Special-environment workover rigs. The desert workover rig: - This workover rig is designed and manufactured in accordance with API Spec Q1,. 4F, 7k, 8C and technical standards of RP500, GB3826.1, GB3836.2, GB7258,. SY5202 as well as "3C" compulsory standard. - The whole rig structure is compact and highly
Our pioneering technological advancements in rig manufacturing, such as drawworks components and AC/DC control systems, serve oilfield service companies locally and internationally . Major operators around the globe rely on the superior quality of Stewart & Stevenson rigs . We offer: www.stewartandstevenson.com
1. ONSHORE WORKOVER RIG. 1.1 FREE–STANDING WORKOVER RIG. Compared with a normal work over rig, the free-standing workover rig is much more stable as its mast structure center coincides with the loading point in the same direction. It is easy to install the mast without needing to adjust the mast tilting angle.
crew n: 1. the workers on a drilling or workover rig, including the driller, the derrickhand, and the rotary helpers. 2. any group of oilfield service workers. crooked hole n: a wellbore that has been drilled in a direction other than vertical. crossover sub n: a sub that allows different sizes and types of drill pipe or other components
material in the formation to remove skin damage caused by drilling, completion, workover operations or plugging caused by precipitation of deposits from produced water or oil. 8. MODULAR WORKOVER RIG. Offshore Modular rigs are platform mounted workover rigs and consists of light weight components that can be
improving solutions. Each iteration has two main steps: perturbation in the current neighborhood and local search. The main components of the heuristic are described next. 2.1 Initial solutions. Construction heuristics for the problem of scheduling workover rigs have been proposed and evaluated in [3, 8, 9]. Heuristic H1 is
and workover rigs, whether it's for drilling, repairing, re-entering or Quick Rig Unit. Hydraulic workover (HWO) units are self-contained, portable, running and pulling systems that provide an economical means of performing routine well maintenance for land, inland waters and the site with all of its components connected.
