The Warrior Well Logging System for pulse type tools employs advanced software and widely available hardware to provide a cost-effective solution to well logging requirements in cased hole applications.
The system supports most down hole tools using pulse type data transmission. It also includes a connector for input of analog signals allowing the system to be used as a data recorder. The operator interface includes a display of the positive and negative pulse heights (obviating the need for an oscilloscope), and discriminator levels may be set manually, or automatically by the software.
Services are predefined so that the operator simply selects the required services and is presented with a fully configured service set up with the last tool string and calibrations run. If other tools are to be run, the graphical tool string editor is used to select the required tool and load the appropriate parameters and calibrations.
Data monitors include raw and calibrated data of all sensors, including depth and line speed. Multiple log plot windows may be opened for comparison of, for example, main and repeat log sections. Log plots may be paused and scrolled to any depth and annotations added, while data acquisition continues.
Depth correlation may be performed while logging, with the screen plot and system depth updated until correct depth is attained. Log curve scales and other presentation parameters may be adjusted while logging and the screen plot redrawn until the desired output is obtained.
The hardcopy plotter may be stopped and started at
any time, presenting any interval with any desired presentation
format. Multitasking allows log-heading data entry, log faxing, and
other ancillary tasks to be performed while logging continues. In
this way rig time is reduced and logs are delivered faster.
Intel Pentium™ or AMD Athlon Based Computer
The system normally uses a notebook computer with integrated USB port for data acquisition. The specification includes an active matrix screen and external ports for modem and mass storage device connection.
Tool Interface and Power Supply
A compact tool interface and power supply is provided which is suitable for the most down hole tools. It includes a tool power supply, depth encoder and line weight sensor interface, as well as circuitry for pulse detection, collar logging, and analog inputs as previously mentioned. The primary functions of the tool interface are controlled from Windows by means of slider bars.
Hardcopy Support
Generation of the final log print with heading, annotated log sections, calibrations, tool string diagrams, etc., is easily achieved. The system supports most well log plotter types currently in use, including color and the generation of multiple copies using fanfold paper. The system also supports PDF and fax format file as a plot output, which may then be transmitted, to a remote fax machine using a conventional fax modem.
