International Logging, Inc. has developed a full suite of integrated online and offline Mud logging and drilling software utilizing the latest MS Windows application development technologies and implementation strategies. We were one of the first companies to successfully implement reliable real-time data acquisition (Drill Logic System) using the Windows operating system. ILI continues to gain experience and develop extremely fast and robust applications that run in the latest MS Windows 32-bit operating systems.
The Drill Logic System software is optimized for real-time data transmission over a local area network (logging unit and rig site) and wide area network via the internet or corporate intranet. This flexibility allows cost effective viewing of real-time data by multiple clients wherever required.

MUD LOGGING DRILL LOGIC SYSTEM
 The Drill Logic System Server (DLS) is an extremely reliable and fast software application responsible for all real-time Mud logging and drilling data services. DLS is used primarily by the data engineer to calibrate sensors, set parameters, configure screens and set data archival options. Once running, DLS scans all the sensors once per second and displays the calculated and drilling logic results.
Besides making hundreds of engineering calculations in just a few milliseconds, DLS is also responsible for maintaining an online MS Access database, providing real-time data to DLS Clients, servicing historical data requests from DLS Clients and setting internal and external alarms. All these features and its proven field record make Drill Logic System the premier Mud logging on-line system.

MUD LOGGING DRILL LOGIC SYSTEM CLIENT
 The Drill Logic System Client (DLS-Client) software provides real-time alpha-numeric and graphical displays of mudlog and drilling data on networked PC workstations. This allows networked users to view real-time data across the rig-site or across the world! DLS Client displays are created by the user and saved as files that may be recalled at any time. Both graphical and alpha-numeric windows may be configured and viewed simultaneously. Everything on the screen is configurable so there is no limit to the types of displays that may be created.
This DLS Client workstation installed on the rig-floor is used for stand alone operations and allows the user to command the DLS software remotely.
The explosion proof enclosure contains a powerful Pentium computer and high resolution LCD display specifically designed for harsh industrial environments.
With stand alone operations the full power of DLS and DLS Client is available through optimized function key menus but a built in mouse is available if the user prefers. DLS Client is so powerful it could be used to command DLS even over a corporate WAN or the internet if the appropriate permissions are set.
There is no limit to the number of DLS Client workstations that may be connected to the network. International Logging, Inc. uses sophisticated client-server techniques that places most of the data and user interface processing on the client computer. This not only allows for a far greater number of workstations to be serviced but also saves valuable network bandwidth and allows data to be transmitted more frequently. Two second transfer intervals are not uncommon even over a WAN! Of course like everything else with DLS Client even the transfer interval may be selected by the user and separate workstations can set their own intervals.
If you have access to your corporate intranet you can view real-time data and playback data with DLS Client.
DLS Client is a standard MS Windows program so you can multitask it with the rest of your applications. There is no need to have it running 24 hours a day just connect when you want data. Historical data is retrieved from the on-line data in the logging unit and you download only the data that you request so you won't be frustrated by long downloads.
If you already have a network connection to the rig-site you can install DLS Client on one of your office computers with no additional hardware. If you have a spare communication line we can use that to create a small WAN to your office. At the rig-site we extend our logging unit network to the client workstation location.
DLS Client trouble free setup and operational reliability has been proven time and again in some of the most demanding network environments.
DLS Client Highlight:
• Fully configurable displays including:
a) Depth Curves.
b) Time Curves.
c) Bar Charts.
d) Alpha-numeric.
e) Drilling Status.
• Multi-tasking MS Windows 2000/XP operating system.
• Client Server technology uses low network bandwidth.
• User configurable smart alarms both visual and audio.
• Playback time and depth data over entire well interval.
• View data from multiple rigs on one computer.

MUD LOGGING DRILLING ENGINEERING APPLICATIONS
 The Drill Logic System Drilling Engineering Applications (DLS DEA) is a suite of engineering programs used during drilling operations and for post well analysis. The software may be used either as a stand alone application (offline) or linked to the DLS database (On-line). On-line, the software connects to DLS via a TCP/IP network.
DLS DEA runs on Microsoft Windows 2000/XP family of operating systems and is fully integrated with Drill Logic System.

MUD LOGGING DLS VIibrA
The Drill Logic System Vibration Analysis (DLS VibrA) package is a tool designed to aid drilling and Mud logging personnel in the detection and suppression of harmful drill string vibrations common during harsh drilling conditions.
The DLS VibrA system is designed to detect and quantify the severity of torsional drill string vibration and provide immediate feedback about the results of remedial actions. The system allows the implementation of practical guidelines designed to suppress torsional vibration before it results in BHA failure.
By smoothing out downhole drilling conditions BHA components can expect to yield a longer life before failure thus bringing drilling operations closer to optimum.
The DLS VibrA system consists of one DLS VibrA server that acquires data from standard Mud logging sensors at a high frequency and one or more DLS VibrA Clients that process and display the data.
DLS VibrA Server
The VibrA Server acquires sensor data at the necessary rate to insure sufficient data quantity and quality is supplied to the VibrA Client Applications Digital Signal Processing functions.
The DLS VibrA Server performs the following services:
• Sensor calibration
• Modify data acquisition parameters
• Acquire sensor data and convert to engineering units
• Manage connections for multiple network users
Typically, sensor signals are acquired at a rate of 10Hz which is sufficient for analysing torsional drill string vibrations (typically observed in range of .5 to 2 Hz).
The VibrA Server sends full data packets, at the frequency specified by the operator, to all currently connected DLS VibrA clients. DLS VibrA clients connect to the DLS VibrA server via a local or, bandwidth permitting, wide area network. Windows 2000/XP workstation may connect using the TCP/IP network protocol.
DLS VibrA Client
The DLS VibrA Client software provides real-time display of rotary torque, rotary RPM, hookload, and stand pipe pressure at the frequency the DLS VibrA Server is acquiring data (usually 10 Hz). The real-time data display allows the driller, or other VibrA Client users on the network, to observe drill-string vibrations and the results of corrective actions as they occur.
Sophisticated digital signal processing routines perform complex Fast Fourier Transform (FFT) frequency analysis of the torque signal in real-time. The FFT result, implemented as a Power Spectrum, detects sinusoidal variations of the torque signal and analyses those variations for frequency and magnitude. The displayed results, represented by the Power Spectrum graph and RMS (root mean squared, a measure of the magnitude of the variation) gauge provide a measure for the torsional vibration.
 Detailed post-drilling analysis is provided by easy playback of the raw data. Since data is saved at its acquisition rate (not averaged or smoothed or otherwise altered) the signals are displayed exactly as they were while drilling thus the torque signals power spectrum may be analysed for the presence and magnitude of the torsional vibration. The DLS VibrA Client software will allow historical data playback while the real-time signals are saved to a database to ensure no data is lost.
Alarms will alert the user to adverse drilling conditions based on the standard deviations of signals, paired signal standard deviation, or high torsional vibration.
The DLS VibrA software is a fully integrated client of Drill Logic System thus allowing real-time data network transfer of other parameters such as Depth and Rate of Penetration.
The DLS VibrA software will run on Windows 2000/XP workstations that can establish a network connection to the DLS VibrA Server. |
