What is the difference between wireline and slickline?
While a slickline is a thin cable introduced into a well to deliver and retrieve tools downhole, a wireline is an electrical cable used to lower tools into and transmit data about the conditions of the wellbore. Usually consisting of braided cables, wirelines are used to perform wireline logging, as well.
What is wireline in fracking?
Wireline does the plugging and perforating that precedes the actual fracturing. The fracturing is done by pressure pumping crews using vast amounts of water, sand, and chemicals at extraordinary pressures. Every wellbore is lined with steel pipe. This pipe is known as casing.
What is wireline oil and gas?
In oil and gas exploration, the term wireline broadly defines industry-specific methods, processes, and technologies that lower cables and wires into a wellbore. Wirelines are strong, thin lengths of wire or braided cable mounted on a powered reel.
What is slickline used for?
A thin nonelectric cable used for selective placement and retrieval of wellbore hardware, such as plugs, gauges and valves located in sidepocket mandrels. Valves and sleeves can also be adjusted using slickline tools.
What is a slickline in oil and gas?
Slicklines. Used 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 adjust valves and sleeves located downhole, as well as repair tubing within the wellbore.
What is pump down in fracking?
Pumpdown perforating is a wireline-conveyed method of completing horizontal wells. Fluid pumped from surface is used to convey a plug and perforating guns to a desired depth, where the plug is set and guns are fired, creating tunnels through the casing and cement and into the formation.
What is plug and perf?
Commonly, the “plug-and-perf” stimulation technique is employed in wells with cemented liners. Plug-and-perf includes pumping down a bridge plug on wireline with perforating guns to a given horizontal location near the toe of the well. The plug is set, and the zone is perforated.
What is well wireline?
In the oil and gas industry, the term wireline usually refers to the use of multi-conductor, single conductor or slickline cable, or “wireline”, as a conveyance for the acquisition of subsurface petrophysical and geophysical data and the delivery of well construction services such as pipe recovery, perforating, plug …
What is used to make wireline from well to well?
Lubricator Lubricator is the term used for sections of pressure tested pipe that act to seal in wireline tools during pressurization. As stated it is a series of pipes that connect and it is what holds the tool string so operators can make runs in and out of the well.
What is coil tubing used for?
Coiled tubing applications include drilling operations, hydraulic fracturing, well completions, removing sand or fill from wellbore, and other applications that involve pumping fluids at high temperatures and high salinity.
Who invented slickline?
Minimize risks, improve performance. More than 75 years ago, Halliburton invented slickline services. Today, to cut well intervention costs and boost production, we collaborate closely with customers in every part of the world.
What is pump-down oil?
How does a well pump work?
Fluid above and within the plunger is lifted out of the casing while more fluid is pumped into the well. On the down stroke, the riding valve is opened and the standing valve is closed. Fluid flows into the plunger and no fluid is allowed to leave the well.
How did they pump oil from wells in the 1800s?
At each well, a steam engine rhythmically raised and lowered one end of a sturdy wooden beam, which pivoted on a Samson post. The walking beam’s other end cranked a long string of sucker-rods up and down to pump oil to the surface.
How many barrels of oil does a well pump produce per hour?
Assume a 2.25 inch pump bore, running 10 strokes per minute, with 30 inches of fluid entering the pump bore each stroke, you would move about 177 barrels of fluid per day. A normal oil well might have an oil cut of 10%, so that well would produce about 18 barrels of oil a day, or about .75 barrels per hour.
What type of pump do I need for my well?
A stationary barrel, bottom anchor pump can be used in shallow to very deep wells, and is typically the most accepted insert pump option. Due to the design, the traveling valve has the option to be smaller than the standing valve.
