Able joins the Tengizchevroil team specifying and delivering advanced instrumentation systems for flow and level measurement on the Sour Gas Injection and Second Generation Projects in Kazakhstan

Tengizchevroil (TCO) has recently started field construction for its Sour Gas Injection and Second Generation Project to increase production and to establish state-of-the-art technologies for gas injection in Kazakhstan The combined project, SGI/SGP, is the next TCO major production expansion

It is expected to be online by early 2007 and increase oil production from 13 million tonnes per year.

This will bring TCO production up to about 25 million tonnes per year.

Well construction scope for SGI/SGP includes 39 producers and 8 injectors.

Major new surface facilities include a Field Production Gathering System, the main SGP Process Plant, the SGI Compressor Plant, and new product export infrastructure (gas export pipeline, added crude storage, LPG Storage, sulphur forming).

Major new infrastructure, being created to allow safe and efficient construction, includes a 6,500 bed construction camp, a new rail line spur, and a new road between the construction camp and SGP construction site.

Parsons Fluor Daniel (PFD) works on behalf of TCO as the prime contractor for Engineering, Procurement, and Construction Management of the facilities portion of SGI/SGP.

PFD holds the majority of subcontracts and purchase orders for this project.

PFD is a joint venture between Parsons Energy and Chemicals and Fluor Daniel.

Following a very successful initial expansion project in 2000, where Able supplied Radar Level Gauges for the refinery itself, Able is pleased to be involved in this further development.

Having been awarded contracts for supply of gas and liquid clamp-on ultrasonic flowmeters, nuclear level instrumentation and a framework agreement for the supply of radar and guided wave radar level transmitters, Able will be supporting not only the refinery itself, but also utilities measurement management for the whole support village.

The Level Transmitter Framework Agreement allows for a myriad of gauge combinations, permitting the on-going specification of instruments against agreed costs with options for antenna sizes, exotic wetted materials, flange sizes and ratings.

Associated hardware such as stilling wells are included, of which Able have extensive experience in fabrication, gauge assembly and testing.

Supply of equipment from within this framework has already commenced and current expectation is that a total of 135 radar and GWR instruments will be required.

RF admittance level transmitters have been added to the framework to offer the capability of fulfilling applications not suitable for radar or GWR technology.

Due to the harsh environmental conditions at site in Kazakhstan, the instruments must be capable of operation and approved for use in hazardous areas in ambient temperatures ranging from 36C to +44C.

The radar installations follow a two-wire, loop powered and intrinsically safe philosophy and will be employed in areas ranging from oil and gas and sulphur recovery to underground liquefied gas storage and utilities.

Clamp-on flowmeters from Able were selected as these are completely non-invasive and virtually maintenance free.

Project requirements dictated that pressure losses were to be kept to a minimum and applications critical to the process meant that the meters must be maintained without shutdown.

A major concern for the project was the reliability of the clamp-on transducer mounting assemblies, for which Able proposed their Rigilok mounting system.

This assembly was developed by Able Instruments specifically for remote installations in harsh environmental conditions.

By providing secure transducer location and fully enclosed covers for complete environmental and physical protection, it negates any concerns with regard to the permanent nature of surface mount technology.

The Wide Beam ultrasound transmission chosen by PFD provides the user with many unique benefits.

Wide beam transducers are frequency matched to pipe sonic properties to maintain operation under aerated/wet conditions and permit accurate operation over a wide range of flow rates and fluid properties.

Automatic zeroing eliminates the effects of drift by automatically and continuously correcting for the drift-causing factors.

To compliment the flowmeters, Able are supplying a fully integrated Ethernet system to allow remote interrogation, diagnostic analysis and configuration of the flowmeters.

The varied Nucleonic level gauging measurement requirements, which include interface control on separator vessels and foam detection on flash drums, necessitate the use of a broad range of techniques.

These encompass nucleonic continuous, single point level and a complete vessel density profiling.

Able have applied their high sensitivity detector/low source activity approach to the project, which is highlighted by the use of unique flexible fibre optic transmitters to contour cylindrical vessels and point scintillators to provide optimum speed of response for critical shutdown duties.

The selection of equipment combines cutting edge nucleonic gauging technology with the ability to operate reliably in the harsh environmental conditions at site in Kazakhstan (hazardous areas with ambient temperatures ranging from -36C to +44C).

The measurement philosophy dictates that control and shutdown systems utilise independent detectors and an internal source where interface, large diameter or thick walled vessels were concerned or where problems with access existed.

For extremely high resolution measurements of density and magnitude of a process, for example the Flash Drums, a scanning device operating in twin wells and outputting position and consistency is specified.

Once again, unique scintillator based technology provides the high resolution requred for accurate, fast response scanning measurements.

Able have allocated a team of project engineers, headed by Project Manager, Richard Bew, to ensure smooth running and co-ordination of the project.

Product Managers for Nucleonic Gauging - Dave Quelch, Flowmetering Leigh Evans, and Level Instrumentation Richard Sygrove, are all working together at the forefront of this project to handle and process initial supply decisions.

Able is very much looking forward to the continued supply of equipment and services and are proud to be part of the team, making this a fully successful on-going venture for Tengizchevroil in Kazakhstan.
