The logging equipment used currently is supplied by Century Geophysical Corporation, from Tulsa, Oklahoma, USA. All of Century’s tools digitise the sensor measurements downhole. This minimises interference from varying wireline cable lengths and other factors that can alter the data. All measurements from Century tools are calibrated, and are recorded in engineering units. The equipment is housed in various Toyota Land Cruiser, Mitsubishi Canter, Hino 4×4 and trailer vehicles.
Century tools are all built in-house with stringent quality control and used by its own employees.
