Wellvector is the data mining engine for unstructured well data: LLM-aided ingestion pipelines that turn decades of scattered files into wellbore schematics, populated tables and the figures a Plug & Abandonment (P&A) team needs. It creates verified abandonment program components in seconds, with audit trails back to every source document. The engine does the mining, an engineer verifies, and the whole team works from one source of truth. Behind every well sits the same problem: engineers spend up to 90% of their time reading through old, inconsistent documents to get a clear picture before the work can begin. As the industry moves toward large-scale decommissioning, that is a large and growing opportunity. Built for the industry, by the industry. Serving the North Sea and the global decommissioning market.

ADHD is a common and serious condition with a good prognosis if recognized early and treated adequately. Research shows that girls and women with ADHD, due to gender related social bias and biological differences receive their diagnosis several years later than boys and men. Research, health care and and peer support have lagged behind because of gender-specific challenges, and even though we know that female ADHD symptoms, and treatment effect change across the menstrual cycle, there is as of today the chance mitigate negative outcomes and improve quality of life for a substantial, clinically significant and vulnerable group and their relatives is wasted. Letterlife is developed with patients and clinicians, and internationally recognized experts in epidemiology, gynecology and female mental health supported by National Patient organizations for ADHD in Europe.
