Standing inside the unit gives the impression that the unit is much larger than its true physical dimensions. Counter and storage space is plentiful and supplies are always easily accessible. (Figure 1). The sample preparation area is large enough to perform all sample related procedures from washing and drying the sample to autocalcimetry analysis. Chemicals, trays, glassware and other sample related items are stored in this area. The geologist work area is to the left of the sample preparation area and includes a computer station for updating the log and running offline programs. (Figure 2). This area is reserved for the company geologist and SEISBIT® operator. It includes counter and wall space, ample leg room, storage drawers, electrical outlets and network connection ports. A data display monitor is placed in this area. (Figure 3).

ANAX 500 SYSTEM The ANAX 500 is the central data collection system for ILI ’s Mud Logging Unit. It combines the real time information management of ILI ’s WellWizard software with superior data compilation. The combined technologies enable drilling operations to optimize performance and improve economics. Fast The ANAX 500 is ideal for offshore rigs as it provides high speed data acquisition with improved resolution and sensitivity. It provides all the data you need for drilling optimization and hydraulic analysis. Simple The ANAX 500 is a premium rack mounted unit that is easy to use, learn and maintain. It is a full feature unit with complete geologic capabilities. Get the data you want, when you want it. The ANAX 500 is capable and robust handling TVD, Multiple Wells, Import/Export and much more! Reliable The ANAX 500 is highly secure and offers enhanced hard drive function. It saves all main parameters in a MySQL database, with both time and depth based records being stored. Additional databases are used to store information such as bottomhole assembly, drill string, pipe tally and directional survey data. Use these databases to investigate occurrences on the rig or comparisons between wells to optimize drilling rates. The ANAX 500 is an expandable system with 40 standard channels and up to 64 analog sensor inputs. The Anax 500. Summary of Features • Full support of Spanish, Chinese, Russian • Unlimited casing, hole and pipe profiling • Intuitive pipe tally/BHA application • Multiple well access • Configurable displays • Import/Export compatible • Trip Monitor • Calcimetry • Versatile trend analysis • Vibration Monitoring   The ANAX 500 System Basics The ANAX 500 is comprised of five main units, which include a Central Processing Unit, Depth Processing Unit, Data Acquisition Unit, Total Gas Unit and High Speed Chromatograph. Central Processing Unit The CPU offers eight channel serial, dual hard drive RAID with pluggable hard disk carriers. It is a highly reliable unit with a Unix based operating system. Depth Processing Unit The DPU is a self contained depth system comprising sensors, barriers and a processor, generating depth based calculations. The system measures block movement, hookload, together with drilling and heave compensation in order to generate depth and penetration parameters. Block movement is typically measured with a draw-works optical position encoder although a crown sheave proximity sensor is optionally available. Data Aquisition Unit The DAU’s modular computer interface signal conditioning boards (electronic barriers) are easily customized for any project. A single main cable interconnects between the DAU and CPU, dramatically simplifies installation. Total Gas Detection: • WITS output • Stabilized flow • Microprocessor controlled detector • Intuitive onboard calibration process • Enhanced stability, accuracy and resolution High Speed Chromatograph Hydrocarbon shows are often missed or poorly evaluated due to sampling and analysis speed limitations of most conventional chromatographs. ILI ’s High Speed Chromatograph is configured to analyze C1 to C5 in 30 seconds. This chromatograph samples gases such as H 2S, CO2 and a variety of inert gases without additional equipment. Standard Speed Chromatograph ILI standard speed chromatograph is configured to analyze C1 to C5 in 90 seconds.  This chromatograph utilizes FID technology. Contigency Plan ILI’s ANAX 500 system has redundancy built in with two independent hard drives. The primary hard drive runs the system and the secondary mirrors the primary for the continual back up of all data. The offshore ANAX 500 system also provides a second CPU unit for redundancy and added protection.

WHAT IS MUD LOGGING

What Is Mud Logging? 
Mud Logging provides subsurface geological information while drilling a well.

Mud Logging examines and analyzes geological information contained in formation cuttings and drilling mud, to determine if oil and gas are encountered during well drilling.  Mud Logging also provides critical safety functions such as determining pore pressure, kick control and ambient gas monitoring.  Mud Logging is used while drilling most exploratory and many development wells, both on and off shore.

Mud Logging services range from basic unmanned gas detection to sophisticated full serviced, manned operations.  Services have evolved to become the information centre for the well and include electronic monitoring of drilling parameters.  These parameters include weight on bit, torque, penetration rate, mud levels, pump speed and third party service provider data.

Basic unmanned services use a cost effective Mud Logging unit that provides simple gas detection to identify potentially productive pay zones and enhance drilling safety.  The system is configurable for hydrogen sulphide Hs2 monitoring . The units are equipped with alarms to alert the user if gas increases or equipment problems occur and works in conjunction with data logging and drilling penetration rates.

Mud Logging Services provides:
• Advanced drilling monitoring systems capable of gas
   detection, electronic monitoring and database recording
   for a full range of drilling parameters on manned or
   unmanned operations.
• Experienced crews and additional tools to monitor and
   analyze both the geology of the subsurface information
   and the drilling parameters.
• Various combinations of services and crew sizes depending
   on customer requirements and well complexity.
• A portable laboratory ( Mud Logging Unit) that houses the
   hardware and software (WW Mud Logging System)
• Analysis conducted at wellsite during the drilling process and samples are returned to the
   operator after analysis.

BENEFITS OF MUD LOGGING

Mud Logging lowers costs and improves the success rates.
Manned Mud Logging uses sophisticated systems and experienced crews, which range from one to six people.  Mud Loggers analyze geological data as well as drilling parameters to identify and quantify productive hydrocarbon reserves, subsurface formation porosity and formation fractures.  This information is used to make recommendations that optimize drilling paths (geosteering) for maximum reserves and production.  Mud Loggers also look at the filling parameters in conjunction with formation analysis in order to provide recommendations to improve drilling rates, reduce costs and enhance safety.
