• Uniquely designed Ground Equipment.

• Telemetry Options which can address any layout requirement.

• Network Capability and Transmission telemetry redundancy.

• The software for operations and QC is dedicated to enhance crew efficiency and lower operating costs.

Cable Telemetry:

LINK : A LINK is a combined unit of FDU's(Field Digitizing Units) and cables that can be handled as one very lightweight unit.

LAUL-LAUX : The LAUL and LAUX also ensure the following functions.

• Consolidation of the FDUs data for transmission to the recording system.
• Buffering of local data.
• Processing of instrument tests

  DSU : The DSU(Digital Sensor Unit) uses the most advanced technology, based on a very low noise micro-machined silicon accelerometer.

  LASER LINK : The laser link is a wireless bridge relying on infrared laser transceivers therefore not requiring any frequency licensing. It can be used to relay the data from a line or a transverse, over a distance of up to 1,000m in clear conditions.

  Radio Telemetry

  LRU : Using wireless Line Repeater Units(LRU),portions of the cable network can be replace by radio transmission. The Line cable, or the transverse cable, may be interrupted at any point and connected to another line or transverse cable using a pair of LRUs.

REM : In order to increase the distance over which radio operates effectively, new modules called Remote Eagle Modules have been developed.

Recording Truck Equipment

CMXL : Using the calculation power of the UNIX SUN Blade Workstations, the CMXL is based on completely new architecture allowing the acquisition of up to 10,000 channels per module in real-time. The CMXL is made of a set of LCI/LMP pairs of boards, to connect the field spread to the Central Unit and the Processing Module(PRM).

 

A new system brings to the World of Marine seismic acquisition two major break-through advanced flexible architecture for an optimal productivity & small diameter fluid. This advanced flexible architecture fulfills the requirements like on-board, the Central Unit of this System can be interfaced with any of the external systems used in the instrument room and the auxiliary channels acquisition unit can be easily placed in the most convenient location. The solid cable design offers increased noise attenuation over fluid filled sections during periods of marginal weather conditions, thereby extending the data collection windows.

This new system is equipped with different modules such as Control Module, Graphic User Interface, Navigation System Unit, Power Unit, Deck Cable Crossing Unit, Auxiliary Channels Unit, and Source Controller.

Control Module manages the flow of acquired data between the streamers and the various recording and peripherals equipment (Tape drives, plotters, positioning, navigation, QC) via SCSI and Ethernet links. GUI helps us to control us to troubleshoot the system, Navigation System Unit controls all navigation module, Deck Cable Crossing Unit assures the connection between each streamer and the control module. Whereas source controller is an external unit used for controlling the airguns.

There are different types of cables for example, Line Cables, Transverses, Extensions, and Bay-Cables, which are used in seismic acquisition field units. These cables are equipped with the appropriate connectors and adapters perfectly designed and tested to withstand the most stringent field conditions.

The high-grade cables allow for a very large coverage of applications under different conditions, ranging from very cold to very hot temperatures and from dry to wet or sea environment. Resistances, portability, reliability, are the features of modern cables.

The most common method of reflection surveying on land utilizing a non-explosive source is the vibroseis method.This uses tractor-mounted vibrators to pass into the ground an extended vibration of low amplitude and continuously varying frequency, known as sweep signal.

A typical sweep signal lasts for seven or more seconds and varies in frequency between limits of about 10 and 80 Hz. The field recordings consist of overlapping reflected wave trains of very low amplitude corrected for seismic noise, but cross correlation of the recording with the known sweep signal enhances the seismic signals and yield a seismic recording of similar appearance to that which would be obtained with an explosive source.

eSQC-PRO is an optional software package for real-time QC of seismic data which is fully integrated to the 408UL. In order to maintain the Zero-Dead-Time architecture of the 408UL CMXL, all QC functions are performed in parallel with the seismic data acquisition processes,without slowing down crew operations.

Furthermore, eSQC-PRO gives the ability for any authorized person to remotely access in real-time to the seismic data from a standard PC platform connected to the internet.

With the increasing emphasis on the optimisation of recovery from any hydrocarbon development, there is increasing pressure on the geophysicist to find improved and appropriate tools to enable the best utilisation of a reservoir. The VSP provides an accurate tool for mapping small-scale variations in the geophysical and geological environment through which the well has been drilled.

The different types of tools are PiepSeis, Dual Analogue ASR, SST-500, MSR-600 Digital Geophone Array, Dual Analogue SSR etc. PiepSeis is one of the most important tools used at present in high deviated wells.

New challenges are continually confronting seismic processors.The benefits to be gained from increasing integration of workflows and the improving ability to extract more quantitative information from seismic have been advanced by the devlopment of the Vista family within Geocluster,CGG's processing software suite.

The reflector image is built by constructive interference. Data can also be migrated from a floating datum plane. In such a case, the difference in elevation between the source and receiver is taken into account when migrating the data.

For better turn-around, this software can run on several processors at the same time. Because of its parallel implementation, the module makes use of user-defined work directories.

14.Rotary Jet Mixer

Rotary Jet Mixer for Controlling Sludge and Blending in Crude Oil Storage tanks. This is used to prevent sludge accumulations. When installed permanently, it can control sludge efficiently, while operating intermittently. It directs single or opposed jets of crude oil horizontally across the tank, slowly rotating at a programmed rate. This sweeping action across the tank bottom cuts, resuspends, and homogenizes the valuable hydrocarbons that normally would become trapped in the sludge.
