Share this article Share It is also being reported the team of Texan ‘Hellfighters’ who battled the Deepwater Horizon disaster in April , which killed 11 and injured 16, is being brought to Scotland by Total to prevent or tackle a blast. Fears have risen because the Total rig is now surrounded by a giant gas cloud, with a sheen of liquid gas on the water – a tell-tale sign there is a large leak. Total’s shares dived about five percent today as it scrambled to present a strategy to deal with the leak. David Hainsworth, health, safety and environment manager for the company, told the Good Morning Scotland programme that there are risks around the situation. But it poses a risk to anyone close to the source, making capping the well complex. Poison in the gas could also threaten fish and other marine life nearby, although the rate at which it dissipates in air and water meant it was not a significant threat to people on land. On Sunday all staff were evacuated from the Elgin platform. Shell has now removed 85 workers from its Shearwater platform and the nearby Noble Hans Deul drilling rig while the nearby leak is found and stopped, taking the total evacuated from the area to Drilling operations on its Noble Hans Deul rig have been suspended and the wells have been left in a safe state, Shell said. It is being reported that the Total rig, pictured, has a large gas cloud surrounding it and has left a condensed gas slick on the water ‘While the move is purely precautionary and primarily driven by the prevailing weather conditions, and both facilities remain operational, it has been decided to reduce numbers to a more manageable level until the full situation surrounding the Elgin leak has been established,’ a Shell spokesman added.

If a permanent meter tube is not installed in the injection-gas line to the well, provisions should be made for the installation of a portable meter tube before unloading and adjustment of the injection-gas rate to the well. A two-pen pressure recorder should be installed before unloading all gas lift installations. The ranges of the pressure elements in the recorder should be checked before hookup. A typical recorder will have a 0- to or 0- to 1, psig range element for the flowing wellhead production pressure and a 0- to 1, or 0- to 2, psig range element for the injection-gas pressure, depending on the kick-off and available operating injection-gas pressure at the wellsite.

Types of Installations. The two basic types of installations are the “fixed”-pump and the “free”-pump design. In the fixed installation, the downhole pump is attached to the end of .

Sizing Forms Use these pump sizing forms and pump sizing charts to make proper pump selection Wire Sizing choosing correct submersible pump cable is very important. Taking into consideration horsepower, voltage, phase, and distance this chart will point you to the right pump wire for your job Tank Sizing Use this tank sizing chart to determine the correct tank for your pump.

This diagram will illustrate the above ground equipment found in a typical installation with piping and control devices surrounding the wellhead. This diagram will illustrate the downhole equipment typically found in a submersible pump installation. Notice the use of torque arrestors to keep the pipe centered in the well casing thus preventing nicked pump wiring. Also notice the use of a pump shroud kit. This shroud kit installs on the pump by attaching anywhere above the pump screen and extends to the bottom of the motor.

The shroud can also prevent sand from covering up the motor and killing it. If sand reaches the shroud, the sand WILL be pumped out with the water. This is hard on the impellers, but it would literally kill the motor if it can’t be cooled because sand has covered even part of it up.

Water Injection On Wellhead Hook-Up

You may have 40lbs some of the time, but not necessarily all of the time. Post some pictures and more details on the regulator and just what is popping. From what I have learned it typically gets reduced to ounces once it passes thru the pancake as that is what the furnace and various appliances require. The plunger that keeps popping, from what I have learned, does so when the gas supply drops.

The Wellhead is the part of the machine that is at the surface of a well which provides the structural as well as the pressure-containing interface that is used for drilling and production. These two parts are working together to bring oil and gas to the surface.

Leo Tolstoy December 15, Business No Comments In the industry of drawing oil and gas from inner cores of the earth, people are usually confused about the terms Well head Christmas tree. Are these two the same? There are times that Wellhead and Christmas Tree are two interchangeable words. But the truth is, these are different and separate pieces of the equipment. In other words, you need a wellhead to use the Christmas Tree.

But you can use it without the Christmas Tree when drilling.

Hook-up can also be used to describe the tasks required to connect the wellhead Christmas trees to the well flowlines. Hook-up includes structural, process, mechanical, piping, .

Edwin Drake drilled and completed the first known oil well near a small town in Pennsylvania, U. This well, which was drilled with cable tools, started the modern petroleum industry. In , near Summerland, California, U. Williams extended an offshore oil field into the Santa Barbara Channel by drilling a submarine well from a pier. This first offshore well was drilled just 38 years after Col. Five years later, more than offshore wells were producing oil. Production from the California piers continues today.

In , a small company called Indian Petroleum Corp. Instead of building a monumentally long pier, they decided to build a portion of a pier with steel piles and cross-members. Adding a deck and barging in a derrick completed the installation. This was the first open-seas offshore platform and supported a standard ft steel derrick and associated rotary drilling equipment.

In January , a Pacific storm destroyed the steel island.

Other documents used in the development of the CSS configuration are as follows: The usual appearance of them is to have the cause on the left hand side with the effect at the top with a ‘X’ matrix. Sometimes logic symbols are included which make the operator’s engineering design requirements unambiguous. Whilst this is an excellent approach it is rather costly, thus it is infrequently used. Cause and Effect – Some projects categorize cause and effects as part of process document and some other projects consider them an instrument deliverable.

A subsea Christmas (X-Mas) tree is composed of valves that are connected to a subsea wellhead. This is to provide a controllable interface between the well and the production facilities.

Single Zone Completions Design Retrievable Packer System Normally, single zone completions of oil and gas wells allow relative simplicity in the completion design. In the most basic of these completions, absent of significant bottom hole pressure and temperatures, the completion might include only a tubing anchoring device or basic packer to accommodate casing protection or artificial lift equipment. Properly designed, the completion can be installed as designed, and not require removal or redesign for planned treatment of the zone.

For this reason, a broad range of tool designs exist to provide the options necessary, both for the wellbore conditions and the economic considerations of the well. Completions, which may require installation removal for either maintenance or changing well conditions, typically employ retrievable packers. Permanent packers are usually selected for more extreme conditions and where well conditions may remain stable for longer periods.

With either selection, setting options are determined by the well conditions and well site considerations. While retrievable packers are available in mechanical set, hydraulic set, or wireline set models, permanent packers are normally set on wireline or hydraulically actuated. Other accesory components of the completion, including flow control devices and safety systems, must also be designed into the completion to accommodate both existing and anticipated conditions.

A surface controlled sub-surface safety valve is used as an integral part of the tubing string in production or injection wells. The Sub-Surface Safety Valves are used to provide a downhole safety valve meeting regulatory requirements. Seal Bore Packers are usually selected for more extreme conditions and where well conditions may remain stable for longer periods. Seal Bore Packers, permit large full-bore flow passages.

Jump to navigation Jump to search For water well wellheads, see Puteal. A wellhead is the component at the surface of an oil or gas well that provides the structural and pressure-containing interface for the drilling and production equipment. Wellhead gas storage, Etzel Germany Oil well Christmas tree The primary purpose of a wellhead is to provide the suspension point and pressure seals for the casing strings that run from the bottom of the hole sections to the surface pressure control equipment.

If the pressure is not contained during drilling operations by the column of drilling fluid , casings, wellhead, and BOP, a well blowout could occur.
