NIPIneftegaz
A privately owned oil and gas research and design institute headquartered in Aktau, set up in 1997 and given its present name in 2025; according to the company, it was founded as NIPIneftegaz CJSC and has offices in Almaty, Astana, Oral (Uralsk), Kyzylorda and Atyrau. In 2007 the institute described itself as created on the basis of the KazNIPIneft institute; it is not that institute's legal successor: according to the history published by KMG Engineering LLP, the legal succession of KazNIPIneft leads to that company. According to the company, the institute prepares reserves estimates, exploration, trial production and field development projects, technical projects for well construction, designs of field facilities and industrial plants and environmental documents, and studies core and reservoir fluids in its own laboratory centre. State portals confirm that in 2022–2026 it was named as developer of the development projects for the Karaturun Morskoe, Munaibay, Karamandybas North and Tuzkol fields and of facilities projects at the Dunga field, and a subsoil user's filing names it as the author of the Karabulak North reserves estimate approved by the State Commission on Reserves in 2022; work for Tengizchevroil, KPO and NCOC is listed only on the institute's own site. As stated by the organisation, it holds state licences for the design of mining production in the oil and gas sector (class 1), environmental design and standard-setting, category I design and engineering surveys; its testing laboratory is accredited until 6 October 2030 (register of the National Accreditation Centre), and its average headcount in 2025 was 311 (annual statements filed with the state depository).
