Life on an offshore oil rig combines long work shifts, time living at the worksite and scheduled periods away from home. The routine revolves around the job, handover and recovery between shifts. A 12-hour shift is a useful example—not a universal schedule—and accommodation, communications, pay and leave depend on the assignment. [1, 2] This guide …
A directional driller is responsible for operating the required equipment & tools on the oil and gas rigs to follow the directional plan that was previously set and designed by the engineering department. He also coordinates with other rig crew members and senior toolpushers to execute the drilling process efficiently. Before moving ahead, we think …
Coiled tubing companies provide the equipment, crews and technical services used to intervene in wells with a continuous tubing string. For a U.S. project, useful starting points include Cudd Pressure Control, KLX Energy Services, Ranger Energy Services and Halliburton. The right shortlist depends on the basin, well geometry, job objective and available spread—not simply the …
It is intriguing to acknowledge that the oil and gas companies that render you with petroleum products don’t drill the operating fields themselves. Instead, these companies agree with the drilling contractors specializing in drilling operations. The drilling contractors provide the equipment, expertise, and rig crew to perform well drilling at the oilfield site. So, to …
A bridge plug is a downhole isolation device that closes the bore at a selected depth, separating the well above it from the interval below. Conventional designs combine an anchoring system, sealing element and internal closure. The main removal options are drillable and retrievable; through-tubing describes how a tool reaches its setting location, not a …
An oil rig is a massive structure used to drill oil (Check Rig Components) in offshore and onshore conditions. These engineering marvels weigh thousands of tons and are loaded with many functionalities. Drilling rigs come in different sizes and types; some are more fascinating than others. Remember that the biggest oil rigs take billions of …
A packer is a tool used in oil and gas production well, which when set, seals the annular space between 2 strings of pipe or a string of pipe and the open hole. They also must have the capability of permitting production flow through them and onto the surface. As its major functions, a packer …
The variety of methods & procedures available for providing the setting mechanism for the seal elements of a packer leads to a significant number of options for installing and completing a well. Consider firstly therefore the setting methods for wells packers. Each of the possible methods for setting a packer is outlined below: Packer Setting …
A retrievable packer Can be defined as a subsurface tool that runs as a part of the completion string to provide a seal between the casing and tubing and can also be set and retrieved with wireline, mechanical or hydraulic mechanism. The major difference than other types of packers (permanent packers) is that they can …
Offshore drilling companies provide rigs, crews and contracted drilling services for wells beneath the seabed. Examples include Transocean, Noble, Valaris, Seadrill, Borr and regional specialists. Their businesses differ: a jackup contractor, a deepwater floater operator and a platform-drilling service provider are not interchangeable. This directory covers 20 selected contractor and operating-business entries, with fleet information, …
