SandView
Downhole sand detection service
Overview
The innovative tool architecture of SandView™ downhole sand detection service integrates a new sensor design with signal processing and an interpretation algorithm to accurately detect the sand entry points downhole and determine sand production rates from different inflow zones under multichoke settings. The tool is a real-time measurement as opposed to a predictive or computational estimation.
The digital downhole detection and processing system provides enhanced sensitivity to even minute sand entries within a wellbore. The tool detects any grain of sand impacting the detector with sufficient energy. Although SandView service’s high-resolution acquisition can detect single particles as small as 0.1 mm in diameter, the measurement is immune to the typical challenges for sensing elements, such as background noise from tool motion, subsurface interference, and the impacts of fluid and gas jetting.
Applications
- Zonal sand entry quantification
- Geomechanical model calibration
- Well intervention and remediation
- Field completion planning
- Recompletion design
- Proppant monitoring during flowback in multistage frac completions
Benefits
The service detects sand production rates with greater accuracy. SandView service’s efficient interpretation algorithms discriminate particles by their size and energy, apply smart thresholds, conduct QC of the count and detection rates, and determine production rate confidence to provide answers not previously available with conventional measurements using filters or acoustic detection sensors at the surface. Sand counts can be transformed to volume and mass if the particle size and density are known.
SandView service can detect individual particles of sand and determines sand production rates.
