Pumping (oil well)

In the context of oil wells, pumping is a routine operation involving injecting fluids into the well. Pumping may either be done by rigging up to the kill wing valve on the Xmas tree or, if an intervention rig up is present pumping into the riser through a T-piece (a small section of riser with a connection on the side). Pumping is most routinely done to protect the well against scale and hydrates through the pumping of scale inhibitors and methanol. Pumping of kill weight brine may be done for the purposes of well kills and more exotic chemicals may be pumped from surface for cleaning the lower completion or stimulating the reservoir (though these types are jobs are more frequently done with coiled tubing for extra precision).

Importance of knowing quantity

Work involving wells is fraught with difficulties as there is often very little information about the real time condition of the completion. This lack of knowledge also covers potential damage and even loss of well integrity. Therefore it is essential for the operator to pay attention to the pressures as recorded and to the quantity pumped. A premature increase in pressure is sign of a potential blockage and continuing to pump risks burst pressure retaining components. Pumping more than an anticipated amount of fluid is a sign of a loss of integrity and a potential leak path somewhere. In either of these two situations, pumping must be stopped and the potential causes analysed.

Oil!

Oil! is a novel by Upton Sinclair published in 1927 told as a third person narrative, with only the opening pages written in the second person. The book was written in the context of the Harding administration's Teapot Dome Scandal and takes place in Southern California. It is a social and political satire skewering the human foibles of all its characters.

The main character is James Arnold Ross Jr., nicknamed Bunny, son of an oil tycoon. Bunny's sympathetic feelings toward oilfield workers and socialists provoke arguments with his father throughout the story.

The novel served as a loose inspiration for the 2007 film There Will Be Blood.

Characters

Oil

An oil is any neutral, nonpolar chemical substance that is a viscous liquid at ambient temperatures and is both hydrophobic (immiscible with water, literally "water fearing") and lipophilic (miscible with other oils, literally "fat loving"). Oils have a high carbon and hydrogen content and are usually flammable and slippery.

The general definition of oil includes classes of chemical compounds that may be otherwise unrelated in structure, properties, and uses. Oils may be animal, vegetable, or petrochemical in origin, and may be volatile or non-volatile. They are used for food, fuel, lubrication, and the manufacture of paints, plastics, and other materials. Specially prepared oils are used in some religious ceremonies as purifying agents.

Etymology

First attested in English 1176, the word oil comes from Old French oile, from Latin oleum, which in turn comes from the Greek ἔλαιον (elaion), "olive oil, oil" and that from ἐλαία (elaia), "olive tree", "olive fruit". The earliest attested forms of the word are the Mycenaean Greek 𐀁𐀨𐀺, e-ra-wo and 𐀁𐁉𐀺, e-rai-wo, written in the Linear B syllabic script.

Oil (band)

Oil is a Christian thrash metal band from Long Beach, California, USA. The band was formed in 1997 by Ron Rinehart, the former vocalist with Dark Angel, who converted to Christianity at a Harvest Crusade after Dark Angel's dissolution in 1992. Other members include lead guitarist Blake Nelson (formerly with Deceiver, Desire and Captain Black) and drummer Jason Vander Pal. Oil has released two studio albums and one live album.

In 2004, Rinehart left the band to pursue other non-musical interests. The rest of the group is looking for a new vocalist.

Biography

Oil's first release was a self-financed EP in 1999.

The Refine album was well-reviewed for its honest, no frills metal approach. The band performed live gigs, including a show at the Stryper Expo, but Rinehart received an injury soon after the album release which meant Oil did not perform for nearly a year. Once recovered, Rinehart and Oil returned to performing, being announced as special guests to Disciple in April.

The band recorded a live album Choice Cuts Off the Chopping Block at the First Baptist Church in Downey, California, in November 2002. The record included two new acoustic songs, "This Is My Prayer" and "Medicine Man". When bass guitarist Matthew Joy opted out in May 2003, Oil recruited Jonathan Thiemens of Blind Sacrificies as a temporary replacement. This became permanent in July.

Pumping (audio)

In audio, recording, and music, pumping or gain pumping is a creative misuse of compression, the "audible unnatural level changes associated primarily with the release of a compressor". There is no 'correct' way to produce pumping, and according to Alex Case, the effect may result from selecting "too slow or too fast...or too, um, medium" attack and release settings.

The technique is common in rock and electronic dance music. A celebrated example is Phil Selway's (Radiohead) drum track on "Exit Music (For A Film)", and clear examples include the electro percussion loop in Radiohead's "Idioteque", Benny Benassi's "Finger Food", and the ride cymbals on Portishead's "Pedestal".

Side-chain pumping is a more advanced technique using a compressors 'side-chain' feature which, "uses the amplitude envelope (dynamics profile) of one track as a trigger for a compressor used in another track." When the amplitude of a note of the side-chained instrument surpasses the threshold setting of the compressor it attenuates the compressed instrument, producing volume swells offset from the side-chained note by a selected release time. Found in house, techno, IDM, hip hop, dubstep, and drum 'n' bass, Eric Prydz's "Call On Me" is credited with popularizing the technique, though Daft Punk's "One More Time" contributed, while clear examples include Madonna's "Get Together" and Benny Benassi's "My Body (feat. Mia J.)"

Pumping (computer systems)

Pumping, when referring to computer systems, is simply how many times per clock cycle data is being transmitted.

Early types of system memory (RAM), such as SDRAM, transmitted data on only the rising edge of the clock. With the advent of double data rate synchronous dynamic RAM or DDR SDRAM, the data was transmitted on both rising and falling edges. However, quad-pumping has been used for a while for the front side bus (FSB) of a computer system. This works by transmitting data at the rising edge, peak, falling edge, and trough of each clock cycle. Intel computer systems (and others) use this technology to reach effective FSB speeds of 1600 MT/s (million transfers per second), even though the FSB clock speed is only 400 MHz (cycles per second). A phase-locked loop in the CPU then multiplies the FSB clock by a factor in order to get the CPU speed.

Example: A Core 2 Duo E6600 processor is listed as 2.4 GHz with a 1066 MHz FSB. The FSB is known to be quad-pumped, so its clock frequency is 1066/4 = 266 MHz. Therefore, the CPU multiplier is 2400/266, or 9×. The DDR2 RAM that it is compatible with is known to be double-pumped and to have an Input/Output Bus twice that of the true FSB frequency (effectively transferring data 4 times a clock cycle), so to run the system synchronously (see Front side bus) the type of RAM that is appropriate is quadruple 266 MHz, or DDR2-1066 (PC2-8400 or PC2-8500, depending on the manufacturer's labeling.).
