In the oil and gas industry, the term wireline usually refers to the use of cable, or "wireline," to collect subsurface geophysical and petrochemical data. The subsurface information describes and allows for analysis of subsurface geology, reservoir properties and production characteristics. Wireline can also refer to the delivery of well construction services such as pipe recovery, perforating, plug s. SlicklinesUsed to place and recover wellbore equipment, such as plugs, gauges and valves, slicklines are single-strand non-electric cables lowered into oil and gas wells from the surface. Slicklines can also be used to. .
First developed by Conrad and Marcel Schlumberger in 1927, wireline logs measure formation properties in a well through electrical lines of wire. Different from (MWD) and mud logs,. .
When producing wells require remedial work to sustain, restore or enhance production, this is called workover. Many times, workover operations require production shut-in, but not always.
[pdf] A drilling rig is an integrated system that , such as oil or water wells, or holes for and other construction purposes, into the earth's subsurface. Drilling rigs can be massive structures housing equipment used to drill , , or natural gas extraction wells, or they can be small enough to be moved manually by one person and such are called . Drilling rigs can s.
[pdf] 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.
