Roxar SandLog D High Accuracy Sand /Erosion Monitoring Data Sheet Introduction The effective management of sand is critical for maintaining the integrity of operator assets and optimising oil & gas production. That’s why choosing a sand/erosion monitoring solution is a critical decision for operators, and why the Roxar SandLog D will be a key element of future flow assurance strategies. Together with Emerson's unique multiple element sand/erosion probe and Roxar Fieldwatch software, Roxar SandLog D provides probably the best combination of detection reliability and accuracy for sand/erosion monitoring. Roxar SandLog D is provided in explosion proof design, for service in hazardous areas and with state of the art performance and flexibility. Reads Multiple Element Sand/ Erosion Probes • Covering more of the pipe diameter, enhanced ability to detect sand particles in the flow • Redundancy of elements Improved Performance • More loggers per cable loop • More frequent measurements • Updated electronics, improved performance High Accuracy • 24 bit resolution, or 0.067 ppm of probe element thickness • Power and communication via Field Interface Unit (FIU D) • No internal batteries in instrument units • All raw data available for user for review and verificaton Roxar Fieldwatch Software • Set up and control of system • Data management and reporting • Data sharing between multiple locations • When combining data with flow data, assessment of sand production volumes • Alarms and communication to main control systems via OPC or Modbus protocols Description Measurement Principles SAFE ZONE / ON SITE HAZARD ZONE Junction Box Cabinet located in Control Room DCS Sand/erosion is measured through the erosive effect caused by sand particles hitting the sensing elements of the intrusive sand probe, using high accuracy Electrical Resistance (ER) technology. When combining measured sand/erosion rates with flow rates and assumed sand particle size, sand production can be quantified. Roxar SandLog D Junction Box Roxar CorrLog D Power Com FIU D FIU D System Description Roxar SandLog multiple element sand probes are connected through a connection box and a probe cable to the Roxar Sandlog D instrument (max length 20 meters). This adds flexibility for instrument access even if probes are installed at inaccessible locations. Roxar SandLog D and the Field Interface Unit (FIU D) are powered by an external 24VDC power supply and communicate via the same Field Bus Cable. The FIU D must be installed in a safe zone (normally in a cabinet in the control room), but can also be installed in an explosion proof enclosure in Hazardous area. Data is forwarded from FIU D to a PC server where Roxar Fieldwatch software is installed. A range of communication options are available, RS 232, RS 485, GSM/GPRS, radio, etc. Roxar Fieldwatch provide analysis and reporting functions,and communicates with main control systems through OPC or Modbus protocols. The Roxar Sand/Erosion probes is designed due to the fact that it t is difficult to predict sand distribution in a line, as it depends upon flow velocities and flowline design, which is the basis for the following unique design features: • It is recommended that the sand/erosion probe is installed in a vertical pipe, preferably 10 pipe diameters after a bend, where sand is assumed to be relatively uniformly distributed within the pipe. Sand/erosion probes may also be installed in other positions, e.g. horizontal lines, depending on flow conditions. • The sand/erosion probe is installed into the pipe, with sensing elements facing the flow at an optimum angle, in order to maximize sensitivity and minimize response time for sand erosion and performance. • Multiple elements (max 4) increase the probability to detect sand independently of distribution within the pipe, and also give redundancy with respect to probe measurements and performance. • Probes with a combination of corrosion elements and sand/erosion elements can also be monitored by Roxar SandLog D. Integrated Flow Assurance Monitoring System Roxar SandLog D forms part of an integrated flow assurance monitoring offering from Roxar, that also includes: • Intrusive Corrosion Monitoring (Roxar CorrLog D) • Non-intrusive corrosion monitoring (Roxar FSM) • Non-intrusive acoustic sand monitoring (Roxar SAM) • Non-intrusive acoustic pig detectors • All integrated in one cabinet, and controlled by Roxar Fieldwatch Sofware Integration of the functions above provides commercial and technical advantages in the project, installation, training and after sales support phases - in addition to reduced hardware requirements since the same cabinet, cabling, and server can be used for multiple functions. Sudden increase in sand production detected by multiple element sandprobe, SandLog and Fieldwatch software.
