Our tools feature multiple integrated sensors, eliminating the need for stacking and reducing the number of logging runs.This stacking yields more data per run and reducesthe total number ofborehole logging runs.
The Spectral Gamma tool is a three-channel analysis of the gross gamma ray spectrum as it relates to potassium, uranium, and thorium content. An internal energy source of less than 1 micro-curries of Cs137 is used to excite the crystal and to stabilize the electronics prior to logging. The spectral window is recorded via a 256 channel spectrum board so that the different energy levels from the formation can be analyzed.

The Multi-Parameter E-Log, Neutron logging tool was developed to replace the
9055 which was historically Century’s most popular tool. The tool duplicates all parameters on the 9055 while adding the 16 inch normal, 64 inch normal, and lateral resistivities. The 9057 natural gamma circuit features a low dead time and the ability to measure very high count rates making it a favorite for uranium logging. The tool records ten different parameters simultaneously in
one pass of the borehole. The ten parameters are the following: natural gamma, spontaneous potential, single point resistance, 16 in. normal resistivity, 64 in. normal resistivity, 48 in. lateral resistivity, neutron-neutron, temperature, delta temperature, slant angle(tilt) and azimuth (bearing). Slant angle, azimuth, and natural gamma are optional.

The Full Wave Sonic tool contains a single transmitter and dual receiver to record formation travel times. The full wave form data is also recorded simultaneously, along with near and far travel times, borehole-compensated delta time, calculated sonic porosity, receiver gains, near/far amplitudes and natural gamma. The sonic or acoustic log uses the basic principle of sound waves traveling through a media. The Century sonic system uses a single transmitter and dual receiver system for recording the travel times of the formation. The receivers are spaced approximately 2 and 3 feet, from the transmitter. Therefore, a 0.3m (1 ft.) calculation can be made to measure this interval transit time. Additionally, the 9320 can be upgraded for cement bond logging, by adding a casing collar locator (see below for link).

Continuous velocity flowmeter logs are used to measure the fluid flow rates in open and cased wells. Logs can be run in the up or down direction, with or without the well producing water. Century’s impeller flowmeter uses a magnetic coupling between the sensing device and the electronics so that borehole fluids cannot enter the tool and injected oil is no longer necessary. Internally, a 256-pulse-per-revolution optical encoder records the impeller turns, minimizing statistical problems of other tools. With this low-friction design, low flow rates of less than 0.8 liters per second (3 gallons per minute) can be measured. The tool is configured with a 114 mm (4.5 in.) shroud. An 89 mm (3.5 in.) shroud is also available. Natural gamma is optional.

The E-M Flowmeter tool is used in the environmental and hydrology industries to measure fluid movement in a borehole. It incorporates Quantum Engineering’s “EBF” electromagnetic sensor. The instrument measures flow rates using the principle of Faraday’s Law of Induction. The downhole probe consists of an electromagnet and two electrodes located 180 degrees apart and 90 degrees to the magnetic field inside a hollow cylinder. The voltage induced by a conductor moving at right angles through the magnetic field is directly proportional to the velocity of the conductor (water) through the field.
The tool is capable of measuring low velocity flow rates down to less than 50 ml/min and increased flow rates up to 40 liters/min through the tool’s 1-inch inside diameter sensor. When using the tool to measure low velocity flow rates, a rubber skirt is attached to the outside of the sensor to block off the borehole and force the fluid to pass through the 1-inch diameter opening inside the sensor coil. The Compu-View Software program is designed to allow the automatic collection of data at selected static stations in the borehole. When measuring faster flow rates, the rubber skirt is typically removed and the tool is run in either static station or dynamic mode. The tool has no moving parts.

The Acoustic Televiewer takes an oriented “picture” of the borehole using high-resolution sound waves. This acoustic picture is displayed in both amplitude and travel time. This information is used to detect bedding planes, fractures, and other hole anomalies without the need to have clear fluid filling the boreholes.
The televiewer digitizes 256 measurements around the borehole at each high-resolution sample interval (0.005 meters / 0.02 feet). This data is oriented to North and displayed in real time while logging using the Visual Compu-Log software. Analysis includes color adjustment, fracture dip and strike determination, and classification of anomalies. It allows information to be displayed on the graphical screen, plot, and in report format. Optionally, the tool can be equipped with a natural gamma sensor.
