STAVANGER, Norway – Archer has introduced a new generation of SPACE ultrasound imaging and measurement services, applying techniques such as phased-array beam-forming to facilitate a better understanding of the downhole environment.

SPACE Vernier is designed to maximize well life by measuring the internal and external dimensions of the entire wellbore to generate statistical analysis of localized damage and systemic corrosion.

A no-contact design, claimed to be unique, is said to eliminate the risk of damage to the well tubing.

Archer has also upgraded its SPACE Focus (formerly Forward Viewer) technology to now operate in temperatures of up to 135°C (275°F) and pressures of up to 7,250 psi (500 bar).

SPACE Panorama (formerly Azimuthal Viewer) has been upgraded to operate in 150°C (302°F) and 15,000 psi (1,034 bar) environments and is also available in a 2 1/8-in. size, making it suitable for a wider range of downhole applications.

Another new feature is a high-speed telemetry system which, combined with digital processing, is said to improve downhole 3D image quality.

This should allow operators to more accurately visualize well components to identify and measure damage, and therefore take better decisions on well maintenance and operations, the company claims.
