Vigor Ultra-HT/HP Production Logging Tool 

Vigor Ultra-HT/HP Production Logging Tool (VUPT), without flas, rated 200°C and 140 MPa in both 35 mm and 43 mm O.D..

Manchester-code telemetry supports surface read out or memory mode available through slick-line/coiled-tubing.

Full suite of com panion subs provides long-duration logging capability.

Built with 200 °C-rated imported components, sensors and o-rings, titanium alloy housing and proven HT design.

Key components undergoes burn-in, high-temperature aging screens and full-scale HT/HP qualification to guarantee ultra-high temperature and pressure performance.

Without flask extends maximum logging time in both surface read-out and memory modes. Configuration can be customized, including sour-service option (in environ_x0002_ments containing H₂S up to 20% or CO₂ 10%).

All metallic, non-metallic materials and o-rings are H₂S/CO₂ corrosion tested to ensure compatibility with hostile environments.

The number of HP/HT wells is increasing in many areas of the world, including the North Sea, the Gulf of Mexico, and Southeast Asia. Several factors are responsible for driving the search for hydrocarbons in these hostile environments. Existing fields are becoming depleted, and easier targets are scarce. The high pressure means that relatively more hydrocarbon is contained in these fields compared with normally pressured fields. Moreover, as long as the fields are large enough, they make commercially attractive targets even with the technical difficulties.

Typically, companies put conventional logging tool electronics in Dewar flasks. This helped meet the early challenges of HP/HT environments. As logging expands into more extreme environments that push beyond the safe operating envelope achieved with flasks, new technology is needed to meet the ever increasing demands.

New developments in elastomer technology have allowed operations up to 321°C (610°F). Parfluor Ultra material (PTFE) is used exclusively for these temperatures. The use of metal seal technology has expanded this upper limit to more than 427°C (800°F) for limited times downhole.

Special qualification is needed on all components and modules used in the production logging string. Heat qualification is needed for all tools prior to running in the well. Clear operations plans are needed to limit the time in the well at elevated temperatures. It is very important to work together and make sure all limitations are understood. The detrimental effects of temperature can be seen when the electronics of a new tool are compared with a previously used circuit board. Rigorous job preparation is critical to success in HP/HT logging.

Intensive post-job maintenance is needed for all HP/HT equipment. Many sensitive components, though in working order, are routinely replaced to ensure optimum performance on subsequent logging jobs since temperature cycling often results in failure. High temperatures are particularly wearing on O-rings and seals, so all are replaced before the tools are reassembled and tested.

Electronic components such as integrated circuits are frequently the weakest link in a logging tool. Commercial-grade components require careful testing and qualification if they are expected to go to 175°C (347°F). Temperature increase inside the tool depends on two factors: the heat flow from the outside environment and the heat dissipated by the power consumption of the internal components. The use of low-power components and efficient circuit design helps reduce the internal temperature increase, and the use of a heat-sink to increase the thermal mass inside the Dewar flask slows the rate of temperature increase.

HP/HT tools can be organized into three categories, selected according to commonly encountered technology thresholds. Classification system boundaries represent stability limits of common well-service tool components, elastomer seals, and electronic devices.

• Standard tools are rated up to 150°C (300°F) bottomhole temperature and 10,000 psi bottomhole pressure.
• HP/HT tools are rated for 150°C to 204°C (400°F) bottomhole temperature and 10,000 to 20,000 psi bottomhole pressure.
• Ultra-HP/HT tools are rated for 204°C to 260°C (500°F) bottomhole temperature and 20,000 to 35,000 psi bottomhole pressure.
• HP/HT-hc tools are rated for 260°C to 315°C (600°F) bottomhole temperature and 35,000 to 40,000 psi bottomhole pressure.
