Sand control screen failure is rare but always expensive. A defective slot costs weeks of well downtime and millions in workover. CTRL+ optical metrology turns sand control QC from sample-based paper certificates into 100 % slot-by-slot verifiable inspection — at the manufacturing line and at the operator's incoming audit.
Each sand control screen is scanned end to end with an optical head — no contact, no operator-induced drift. Every slot is captured at 5-15 µm resolution. The instrument computes per-slot width, axial drift across the joint, edge defects and obstructions. A statistical distribution is built (D50, D90, σ) and compared to the screen spec. The result is exported as a PDF certificate aligned with ISO 17824 and a machine-readable CSV that operators integrate into their QC file.
Direct wrap wire wrap sand control screens. The reference geometry for ISO 17824 acceptance.
Wedge wire profile screens with V-shape drainage geometry. CTRL+ measures the slot aperture and the wire profile depth.
Pre-packed sand control screens with gravel-filled annulus. CTRL+ inspects the outer slot layer and inner base pipe.
Machined slotted liners as standalone sand control. CTRL+ measures slot width, length and edge quality.
Yes — slot width is measured every few millimeters along the joint. Axial drift trends (whether the screen tightens or loosens along its length) are flagged with statistical thresholds defined in the screen spec.
2 to 5 minutes per 6-12 m joint. A full horizontal completion of 60 m is inspected in under an hour. Manufacturer throughput is typically 30-60 joints per shift.
Yes — bost+ and most+ are deployed both at screen manufacturers (line-side QC) and at operator receiving yards (incoming audit before deployment).
The output PDF lists slot-by-slot dimensional results and statistical metrics aligned with ISO 17824 §6.3 and API 19SS acceptance criteria. Operators have used CTRL+ certificates as the QC record of acceptance in multiple completions.
Slot apertures from 50 µm to 1000 µm. Screen OD from 2 7/8 in to 9 5/8 in. Joint length up to 12 m per pass.
Wire wrap, direct wrap, wedge wire filter screens — full-batch optical inspection, ISO 17824 / API 19SS certificate output.
