Verif-i

What Verif-i does

Verif-i SG Ltd. is a privately held UK-based quality control consultancy dedicated to maximizing seismic data value in oil and gas, geotechnical, and hydrographic exploration. Founded in 2013 and acquired by Seis GEaR Inc. in 2018, the company operates from Reading, UK, with a global service footprint spanning the UK, Netherlands, USA, Brazil, Saudi Arabia, Madagascar, Tanzania, Singapore, and Australia. Its core offerings comprise independent technical audits (including Technical, HSE, and Maritime audits), proprietary software (the Testif-i suite in Land, Marine, and Light variants with 200+ licenses deployed worldwide), and proprietary hardware (Sandwich Box Mk3 vibrator test system and GPS Sync timing instrument). The Testif-i software supports common seismic data formats including SEG-D, SEG-Y, and vibrator attribute formats such as VAPS, Pelton, and Source Link PSS, and analyzes instrument, source, and receiver test data to confirm equipment performance within specification.

Verif-i monetizes through three revenue streams: software licenses bundled with annual maintenance contracts, direct hardware sales with associated training, and professional consultancy services delivered via a global network of field-experienced contractors matched through the FreeAgent portal. The company maintains a sales-led GTM motion targeting enterprise oil and gas producers (e.g., Saudi Aramco, ExxonMobil), seismic contractors (e.g., BGP, WesternGeco, CGG, Geokinetics), and equipment manufacturers, reaching customers through industry events (EAGE, IMAGE, SEG, OTC, Seapex), direct engagement, and content marketing. Around one-third of audits undertaken have reportedly revealed problems that if undetected would have seriously impaired seismic data, providing the core value-prop metric for the independent verification service.

The company is led by Managing Director Dirk Fairclough (appointed December 2025), succeeding Kevin Sweetman, with a leadership team that includes a Technical Director, Business Development Director, Operations Manager, and HSE Advisor. Verif-i is a member of the International Energy Consultants Organisation (IECO), providing indirect access to International Oil and Gas Producers (IOGP) specialist committees, and is in the process of relocating to new Reading headquarters from January 2026.

Core offering

Verif-i provides independent seismic technical audits, QC consultancy, and specialized hardware and software for the seismic exploration industry. Its commercialized products include the Testif-i software suite for processing instrument, source, and receiver tests, the Sandwich Box vibrator test hardware, and GPS Sync timing instruments, all backed by a global network of field-experienced seismic crew consultants.

Product overview

Verif-i is a quality control consultancy specializing in seismic data acquisition with a portfolio of software and hardware products. The core Testif-i software suite processes and analyzes instrument, source, and receiver test data across three variants: Testif-i Land (land seismic systems), Testif-i Marine (marine seismic systems), and Testif-i Light (streamlined field version combining land and marine modules). The Sandwich Box Mk3 provides independent vibrator testing hardware with its own acquisition and processing software. GPS Sync is a precision timing instrument for recording event times with microsecond accuracy. These products work together as an integrated QC ecosystem for seismic exploration operations, with Testif-i software analyzing data from field hardware and providing graphical results for quality assurance.
