Investors | Careers LAB ANALYSIS AND REPORTING SAMPLE ANALYSIS Analysis of oil, water and gas samples are performed using high-resolution liquid or gas chromatography-mass spectrometry. These instruments can detect the presence of tracer chemicals at concentrations as low as parts-per-trillion. All sample preparation and analytical processes include additional internal samples to ensure rigorous quality control of our data prior to reporting. Once samples are received at our laboratories, the normal turnaround time for data from water samples is 2-3 business days. Oil samples typically require 7–10 business days, while natural gas samples typically require 7–14 business days. DATA ANALYSIS Standard reporting for all NCS tracer diagnostics projects is done using TIBCO Spotfire® Analytics software. Reports are updated on a regular basis by NCS’ team of engineers who provide interpretation summaries during each update. Our engineering team can integrate customer supplied data sets to enhance the tracer data interpretation. 00:00 | 00:51 UNDERSTAND YOUR WELL WE WOULD LOVE TO HEAR FROM YOU.

Investors | Careers INNOVUS™ CONVERTIBLE SLEEVE This special-purpose, dual-inner-barrel sleeve can be converted post-frac or post-production to a regulated water-injection mode. The injection barrel is shifted into position across the sleeve ports using a stroker tool deployed on coiled tubing. Injection regulation is provided by the Torius™ calibrated tortuous flow path, which induces back pressure without relying on small-diameter orifices that are prone to erosion and plugging. Typically part of a cemented completion string, but can be deployed in open-hole completions. Sleeves are operated by the Innovus™ frac-isolation assembly deployed on coiled tubing or jointed pipe. No pumpdown plugs or balls required. No drillouts needed. Sleeves can accommodate frac rates up to 80 bbl/min (12.7 m3/min). Sleeve make-up length is 40 in. (101.6 cm) or less, allowing frac-port spacing as close as 15 ft (4.6 m). Compact and easy to handle, with no pup joints required for API connections. Sleeves can be torqued through. Sleeves can be installed in any order, unless port sizes are varied along the lateral on request. Proven NCS MULTICYCLE® sleeve functionality for stage-by-stage wellbore management. Also available in OpenOnly versions. Optional Shift-Frac-Close® sequence stops proppant flowback and allows fracs to heal before reopening sleeves for production.
