Ice pad i-rig drilling rig

Exploration drilling projects in arctic and northern regions often take place in remote, cold, isolated and demanding locations such as lakes, muskeg areas and oceans. One of the major challenges for these projects is the lack of infrastructure making it unfeasible to employ barges or drilling vessels to support project. . Ice pads can be grounded or floating depending on the water depth and the ice thickness required to support the intended loads. The design load should account. . Ice pads can be constructed by free-flooding, with spray ice or with chipped ice. Typically, free-flooding is the most cost effective construction method however. . The bearing capacity of the ice pad depends on the quality of the constructed ice. Proper construction procedures must be employed to ensure the highest ice. [pdf]

Oil rig drilling depth

In the oil and gas industry, depth in a well is the distance along a well between a point of interest and a reference point or surface. It is the most common method of reference for locations in the well, and therefore, in oil industry speech, "depth" also refers to the location itself. Strictly, depth is a vertical coordinate. . Although it is an intuitive concept, depth in a well is the source of much confusion because it is frequently not specified correctly. Absolute depth should always be specified with three components:• a. . Specification of an absolute depth: in Figure 1 above, point P1 might be at 3207 mMDRT and 2370 mTVDMSL, while point P2 might be at 2530 mMDRT and 2502 mTVDLAT.. . • • • Log Data Acquisition and Quality Control, Ph. Theys, 1991, Editions Technip . • Well depth values taken during the drilling operation are referred to as "". The "total depth" for the well, core depths and. . • Unit: the usual unit of depth is the metre (m).• Path: common expressions of path are measured depth (MD) – elsewhere often known as along hole depth (AHD) – and true vertical depth (TVD). Note that using TV for true vertical. [pdf]

Run casing drilling rig

Before starting casing, the drilling supervisor should hold a pre-job safety meeting and confirm the following with the crew: 1. Remove unnecessary tools. 2. Good Housekeeping before the job 3. Rig up Casing handling equipment: Using appropriate hand. . A circulation sub, fitting the casing thread, equipped with a WECO connection, shall be readily available on the rig floor at all times during casing running. [pdf]
