Upper Completion

Production Packers

A device used to isolate the annulus and anchor or secure the bottom of the production tubing string. A range of production packer designs is available to suit the wellbore geometry and production characteristics of the reservoir fluids.

Packers can be run into a wellbore with a smaller initial outside diameter that then expands externally to seal the wellbore. Packers employ flexible, elastomeric elements that expand. The two most common forms are the production or test packer and the inflatable packers. The expansion of the former may be accomplished by squeezing the elastomeric elements (somewhat doughnut shaped) between two plates, forcing the sides to bulge outward. The expansion of the latter is accomplished by pumping a fluid into a bladder, in much the same fashion as a balloon, but having more robust construction. Production or test packers may be set in cased holes and inflatable packers are used in open or cased holes. They may be run on wireline pipe or coiled tubing. Some packers are designed to be removable, while others are permanent. Permanent packers are constructed of materials that are easy to drill or mill out.

Surface & Subsurface Safety Valve

A safety device installed in the upper wellbore to provide emergency closure of the producing conduits in the event of an emergency. Two types of subsurface safety valve are available: surface-controlled and subsurface controlled. In each case, the safety-valve system is designed to be fail-safe, so that the wellbore is isolated in the event of any system failure or damage to the surface production-control facilities.

A downhole safety valve that is operated from surface facilities through a control line strapped to the external surface of the production tubing. Two basic types of SCSSV are common: wireline retrievable, whereby the principal safety-valve components can be run and retrieved on slickline, and tubing retrievable, in which the entire safety-valve assembly is installed with the tubing string. The control system operates in a fail-safe mode, with hydraulic control pressure used to hold open a ball or flapper assembly that will close if the control pressure is lost. Giant Oil Tools FZ design and manufacture Surface and subsurface downhole safety valves that are tubing run and surface controlled, as well as wireline run. Giant Oil Tools FZ range of tubing retrievable surface controlled subsurface safety valves suits all sizes of tubing, in both standard and slim designs. Metal-to-metal body connections are used to eliminate any potential leak paths.

All Giant Oil Tools FZ safety valves equipped with an exercise and lock-out facility. With a landing nipple profile in the top sub a wireline retrievable safety valve can be installed within the tubing run valve bore after lock-out allowing the well to continue to produce.

A full range of accessories are available for the downhole safety valves including exercise/lock-out tools, separation sleeves and nipple protection sleeves.

Wellhead and X-Mass Tree

The set of valves, spools, and fittings connected to the top of a well to direct and control the flow of formation fluids from the well.  An assembly of valves, spools, pressure gauges and chokes fitted to the wellhead of a completed well to control production. Christmas trees are available in a wide range of sizes and configurations, such as low- or high-pressure capacity and single- or multiple-completion capacity. A wellhead is used at the surface of an oil & gas well that provides the structural and pressure containing interface for the drilling and production equipment. Christmas Tree is an assembly of valves, spool, pressure gauges and chokes fitted to the wellhead of a completed well to control production. Giant Oil Tools FZ offers these in a wide range of sizes and configurations, such as low – or high – pressure capacity.

Giant Oil Tools FZ offers the complete range for low cost applications field proven surface wellheads, gate valves, actuators, casing heads, tubing hangers, spools and adapters, bushing and annulus seal, tees and crosses, tree caps and miscellaneous equipment required for surface well completions from 2,000 PSI to 15,000 PSI with maximum flexibility and user convenience. Installation training and field support is available. Giant also offer ESP Wellhead systems and unitized Wellheads and X-Mas Trees and repair and services.
