Cathedral provides equipment designed and built with a focus on quality. Stringent QA & QC (quality assurance and quality control) procedures combined with extensive personnel training ensure that the best product is used in operations. Our in-house testing capabilities are unique for a company of our size and allow our team to perform in-depth tests to qualify the equipment for field usage. Cathedral’s testing routines and processes improve tool reliability and enable us to deliver dependable solutions to our clients.
We have instituted a comprehensive maintenance program which includes standardized job procedure manuals for the assembly and dis-assembly process. As part of the comprehensive maintenance program, all tubular components are inspected for thread and fatigue damage, and magnetism. Each drilling motor is then degaussed and placed on our dynamometer which verifies the force and torque capabilities. Our drilling motor fleet is also monitored through our continuous improvement process, which allows us to track individual component life history. This process provides us with the ability to predict component life cycles and implement design modifications for continuous improvement and reliability.
The Vibration Table is capable of testing MWD components at forces up to 50 G’s. Using the data collected down hole with HAWK monitoring system the vibration table can be programmed to accurately reproduce drilling conditions that cause service interruptions, and to test designs for eliminating repetitive component failures.
To ensure our MWD systems are capable of surviving transport in the Artic to functioning in the bottom of a deep Texas wellbore, all electronic equipment built by Cathedral is temperature tested. The Heat Chamber is capable of cycling temperature from -70C to +200C.
Every component we use in our tools is rigorously inspected to ensure tolerances are within specifications. This results in higher reliability downhole. For component inspection, Cathedral relies on a Coordinate Measuring Machine (CMM) which is capable of measuring complex geometry as accurate as 1/1000ths of an inch.
The dynamometer verifies force and torque specifications under simulated operating conditions which enables Cathedral to test new motors and power sections while minimizing adverse impacts to customers.
Cathedral's automated board manufacturing machine can populate PCB (printed circuit boards) in under 10 minutes. This allows Cathedral to manufacture boards in-house and control quality. We can also quickly produce and test prototypes to support fast and economical MWD upgrades.
The flow loop allows Cathedral to develop and test MWD and other downhole tools under flow rates up to 1.4 m3 per minute (350 gpm), and at pressures up to 6,500 kPA (1,000 psi) using various fluid formulations. Cathedral uses the flow loop for technology development and to improve the reliability of its MWD tools and other downhole equipment.
We're not around right now. But you can send us an email and we'll get back to you, asap.
