What Is Pipe Handling Equipment? Pipe handling equipment is the group of tools and machines used to transfer, lift, support, guide, connect and rack jointed tubulars on a drilling rig. The group includes transfer equipment between the pipe racks and drill floor. Other tools handle tubulars at well center and in the setback area. The …
The impression still exists that snubbing or hydraulic workover units are exclusively used on blowouts or otherwise uncontrollable wells, which is false. The running of tubulars under pressure has indeed made it possible to bring many wells under control at a considerable saving to the industry, but the ability to perform many routine workovers- and …
Drilling slips are wedge-shaped segments with special dies inserted inside, which support the pipe when suspended in the rotary bushings. Figure 1 shows drill pipe and tubing slips with three body segments, while slips for drill collars and casing (Figure 2) are made up of many segments. Design The slips in the master bushing use …
The purpose of the marine drilling riser is to extend the offshore well from the top of the blow-out preventer package at the sea bed to the diverter beneath the rotary table. Thus, Drilling fluid returns are obtained, and tools can be easily guided into the well bore. Choosing the appropriate marine riser size based …
The three main mobile offshore drilling rigs are jackups, semisubmersibles and drillships. Jackups stand on seabed-bearing legs during drilling; semisubmersibles and drillships remain afloat. Platform rigs, tender-assisted arrangements and shallow-water barge or submersible units serve other offshore applications. This guide compares how each type works, where its advantages matter, and what can disqualify a candidate. …
The major application of this drilling rig type is for development drilling from platforms (platforms rigs). Only the rig derrick set, including brake cooling, BOP accumulator, and drilling fluid treatment skid, are mounted on the platform. Then, we can install all other equipment on the drilling tender. The drilling tender is usually a barge-shaped structure …
Have you ever been curious about the process of constructing offshore oil and gas platforms? These massive structures, or platform rigs (Largest Oil Rigs), are crucial in extracting valuable resources beneath the ocean floor. But what exactly is a platform rig, and how does it work? Many designs of fixed platforms have been used in …
Jack up Operations & rig move procedures that we will talk about in this article include the following: Jacking System Jacking systems can be grouped into two main generic types: the rack-and-pinion system and the yoke-and-pin system, the first being more common. Within these types, there are two main designs: floating jacking design and fixed …
Jackup rig consists of a buoyant hull with retractable legs. The number of legs varies depending on design, three or four being the norm. Jackups are mobile, and vessels can tow them between locations with the legs fully extended above the hull. Upon arrival, it lowers the legs down to the sea bottom. Then, it …
The Kelly drive bushing engages the master bushing in the rotary (either square drive or pin drive). As the rotary turns, the Kelly drive bushing turns with it to drive the Kelly. At the same time, as the Kelly works down, the rollers in the bushing allow the Kelly free movement and keep it centered in the …
