EvaluMation, LLC developed a real-time data acquisition system for logging data from various sensors placed around a drill rig. Measurements logged by the system include Hook-load, Weight-On-Bit, Pump Pressure, Bit Depth, Pump Strokes, Pit Volume, Temperatures in and out, CO2, H2S, and Carbide. EvaluMation, LLC utilized third party COTS hardware to develop the data acquisitions system hardware, developed the embedded software for the system, and developed the software for a master application that performs mud logging and drill data monitoring.

An image of the mud logging system is shown below.  Sensors monitor the various measurements from the drill rig.  The electrical data from those sensors get transfered to a Data Acquisitions System, where the electrical data gets converted into Universal Datagram Protocol (UDP) messages.  The UDP protocol is very similar to the TCP/IP protocol in that it uses IP addresses to send text messages to devices on a computer network.  These messages are passed through a wireless access point which resides within the data acquisitions system.  Because the data acquisitions device is wireless, it minimizes the amount of cabling required to setup the drill rig.  This also minimizes issues caused by heavy equipment that could easily run over cabling.  Inside a trailer a distance away from the drill rig,  a wireless network card receives messages and displays the corresponding data to a Graphical User Interface (GUI).

A significant amount of money is saved through-out the drilling process and geologists have the proper information at hand to make important drilling decisions. Also, because of the real-time gas graphical display, toxic gas read-outs ensure worker safety.
