T type fitting T-Block allows diversion of flow stream from vertical to a horizontal flow line. The temporary abandonment caps can be retrieved with the same tool that installed them. Christmas tree for a flowing well Over the years, this has been completed in multiple ways: setting off a charge of nitroglycerine in the bottom of the well, creating fissures and cracks in the reservoir formation, using a bullet perforated gun, and the current method of using a jet gun which can perforate the wall of the casing, the cement, and even multiple inches into the rock formation. This allows the fluid produced to flow up through the seating nipple, and to be pumped back to the surface. Mechanical-Type Seating Nipples Mechanical-type seating nipples are not reversible and are around inches in length. The Final String of Casing The number of strings of casing used for a well depends upon how deep the well is. Typically very few operators will use this method.

  • powerDRAW is the premiere well schematic drawing program for the oil & gas Industry. It is the most complete, corporate-wide, downhole schematic drawing.

    The remainder of the diagram is the actual process, often called the Gas Oil. The wellhead sits on top of the actual oil or gas well leading down to the reservoir.

    The welding installation permits the tubing string to be situated at a specific level, and is especially important for a proper pumping unit installation.

    In most cases, the wells are completed by installing the casing all the way through the reservoir. Mechanical-type seating nipples are not reversible and are around inches in length.

    Instead, a mechanical set energizing the seal by hand is used, in which cap screws are made up with a wrench against an upper compression plate on the slip-and-seal assembly to energize the elastomeric seal. Over the years, this has been completed in multiple ways:. When combined with the SH2 Split Speed Wellhead System, this package can save from 24 to 40 hours of valuable rig time.

    On a Christmas tree, a swab valve is the topmost valve providing vertical access to the well for well intervention operations conducted by wireline, slickline, coiled tubing or a snubbing unit.

    The Christmas part is located at the top part a blue box and the wellhead part is the lower section a red box. Figure 5.

    For instance, a cost-effective tubing option used for shallow wells is H, while J is a common choice for wells around 7, feet. Using a perforated mud anchor with an electric drill, or by cutting holes using an oxyacetylene torch.

    The mud anchor is a full joint of tubing placed at the bottom of the string that may be cut off to a certain length. Visited 3, times, 1 visits today. APP-celeration for Oilfield Operators. Figure 8 — Swab Valve.

    Since the tubing has to reach a specific depth within the well, and be placed without being cut or threaded; tubing is usually available in a wide range or random lengths, typically ranging from feet with shorter lengths referred to as pup-joints.

    The temporary abandonment caps can be retrieved with the same tool that installed them. Views Total views. These holes in the tubing are around 1 inch in diameter and are placed a few inches apart on all sides. Figure 8 — Swab Valve.

    In the oil and gas industry, a Christmas tree is referred to as a series of valve & spool Figure 1 – Christmas Tree and Well Head Diagram.
    If one master valve cannot function properly, another valve can perform the function. Correlating Perforations One of the most important duties while installing the tubing into the hole is placing the casing perforations in the best desired depth away from the surface. Example of a casing hanger with hanger locking devices.

    However, unlike packers, the holddown does not create a seal between the tubing and the casing in the annular space. One is called a lower master valve and another is an upper master valve. Learn how your comment data is processed.

    Cased-Hole Completion To determine what type of completion will be done, an analysis is done on the cutting samples received as the bit drills through the ground and into the reservoir containing the hydrocarbons. Tubing In order to increase the strength, and reduce the possibility of production loss; tubing should be seamless, and not a welded pipe. Visibility Others can see my Clipboard.

      Christmas tree for a two section wellhead The Casing Head The casing head is usually welded directly to the casing, and can have external threads, a slip-on collar, or internal threads.
