Environmental protection is a critical factor for this project - which will operate in a sensitive ecosystem. A key factor in the selection of Parker is its unique interconnection technology that eliminates traditional taper threaded connections in favor of high-integrity compression seals.
The agreement was awarded by Agip KCO, operator of the North Caspian Production Sharing Agreement. It is the culmination of over two years of effort by Parker staff in the UK, Italy and Kazakhstan - working with Agip KCO and the various engineering and operator parties on specifications and supply arrangements.
"Kashagan is probably the most significant oil find of the last 30 years", says Parker Instrumentation's European Marketing Manager, Richard Roebuck. "It's also a technically demanding project, and is a showcase for engineering development investment made over several years by Parker to build an instrumentation product range that eliminates leak-prone taper-threaded connections".
A very wide range of instrumentation products, in both stainless steel and exotic nickel alloys, will be required for the Kashagan project, which will have offshore production and onshore processing facilities. These include ball and needle valves for controlling oil and gas flow, manifolds for connecting the pressure and flow measurement instruments, and both twin-ferrule and high-pressure tube fittings for interconnecting the instrumentation system.
In what is believed to be a first for the oil and gas industry on a major project like this, all the manifolds are required to include a unique Parker technology known as PTFree which integrates A-LOK compression tube fittings. This eliminates the need for taper threaded connections, and the liquid or tape materials that are required to get a good seal. The result is a connection system that is less prone to leakages and problems, and one that typically has fewer potential interconnection points and therefore potential leak paths.
The partners in the North Caspian Sea Production Sharing Agreement are Eni, BG, ConocoPhillips, ExxonMobil, Inpex, Shell and Total. Eni of Italy is the Operator for the partnership. The investment that will be made to develop the full Kashagan field is estimated at some US$29 billion.
