Roxar SandLogHigh Accuracy Sand/Erosion Monitoring
Product Data Sheet 01.12.2016
The effective management of sand is important for the integrity of oil and gas assets and for optimizing production.
Together with Emerson’s unique multiple element sand/erosion probe and Roxar Fieldwatch software, Roxar SandLog provides probably the best combination of detection reliability and accuracy for sand/erosion monitoring.
For optimized sand monitoring, it is suggested to combine in-line sand/erosion probes with non-acoustic sand detectors (SAM, see separate data sheet).
Reads multiple element sand/erosion probes
• Covering more of the pipe diameter, enhanced ability to detect sand particles in the flow
• Redundancy of elements• Can also read combined sand/erosion/corrosion probes
Configuration flexibility
Roxar SandLog is available with a range of communication options:
• SandLog Terminal (Continuous off-line data logging, data retrieval through field terminal)
• SandLog Field Bus (Digital data through Roxar Field Bus) • SandLog 4-20 mA (Analog) • SandLog 4-20 - Terminal (combined) • SandLog Wireless is also available with WirelessHART®
communication (see separate data sheet)
Observe that sand production, and thus erosion rates, may change rapidly. Therefore, digital, on-line configuration is recommended for permanent sand/erosion monitoring.
Roxar SandLog Features
• 24-bit instrument resolution (24 bit correspond to 0.06 ppm of sensing element thickness)
• Up to 20 meter probe cable adds flexibility for positioning of instrument for convenience and maintenance
• 1,500 measurement memory• Intrinsically safe certification• No internal batteries in instrument units (Field Bus version)• All raw data available for user for review and verification

Measurement Principles
Sand/erosion is measured through the erosive effect caused by sand particles hitting the sensing elements of the in-line sand/erosion probe, using 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 Configuration Options
For all SandLog options, in-line probes are connected to SandLog through a probe cable (max length 20 m). A probe connection housing is used for connecting probe leads to the probe cable.
SandLog Terminala (Off-line).In this version, a battery powered SandLog instrument is set up to monitor the probe continuously (measurement interfals from every 2 minutes to every 24 hours). Data is stored in SandLog, and retrieved by the use of a portable terminal.
SandLog Terminal is powered with commonly available AAA alkaline batteries.
SandLog Terminal can be upgraded to SandLog Field Bus by changing the instrument’s interface card.
SandLog Field Bus (On-line).For on-line, digital communication, SandLog instruments are powered and communicate through cable via a Field Interface Unit (FIU)b. The FIU needs to be installed in safe area (could be an explosion proof enclosure). Each FIU can handle up to 8 SandLog instruments (2 cable loops, maximum 4 SandLog instruments per cable loop). Observe that CorrLog and SandLog instruments can be combined in the same cable loops.
The FIU communicates with PC/Fieldwatch softwarec through a variety of options (RS 232, RS 485, LAN, telephone modems, etc).
In this version, SandLog instrument does not contain batteries, and the instrument can be considered maintenance free.
SandLog Field Busd requires Fieldwatch software for operation and data management.
SandLog 4-20 mA.SandLog is also available with communication over an analog 4 - 20 mA communication loop. From the measurements, metal loss is calculated in the instrument, and converted to a signal between 4 - 20 mA. The signal is converted back to metal loss. Observe that for multiple element probes, average metal loss for all elements only is transmitted.
SandLog 4 -2 0 mAe provides data directly to the receiver without the use of Fieldwatch instrument.
The Roxar sand/erosion probes are designed according to the fact that it is difficult to predict sand distribution in a line, as it depends with flow velocities and flowline design, which is the basis for the following unique recommendations/solutions:
• It is recommended that sand/erosion probe is installed in 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.
• 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 probability to detect sand independently on 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.
Sudden increase in sand production detected by multiple element sand/erosion probe, SandLog and Fieldwatch software
• It is suggested to combine intrusive sand/erosion monitoring with acoustic, non-intrusive sand monitors for optimized sand and sand/erosion monitoring in one integrated system.

Roxar SandLog 01.12.2016
The SandLog 4 - 20 mA is powered via the 4 - 20 mA cable loop. Observe that a barrier is required on the 4 - 20 mA cable loop to maintain intrinsically safe certification.
SandLog 4 - 20 mA/TerminalThis version combines the 4 - 20 mA communication with the option of downloading digital data to a terminal for data analysis and reporting.
In this case, SandLog is powered via AAA alkaline batteries.
Integrated Roxar Flow Assurance Monitoring System
SandLog forms a part of an integrated flow assurance monitoring offering from Roxar, that also includes:• Intrusive Corrosion Monitoring (Roxar CorrLog)
• 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 Software
Integration of functions above provide commercial and technical advantages in the project, installation, training and after sales support phase - in addition to reduced hardware requirements since same cabinet, cabling, server can be used for multiple functions.
