Overview

Exillon Energy is a Russian oil exploration and production company focused on developing petroleum assets in two northern Russian regions: Western Siberia and the Timan-Pechora Basin. The company was established in January 2009 by Kazakh businessman Maksat Arip, who assembled an operating portfolio from assets with exploration histories predating the company itself. Its West Siberian properties had an exploration history extending back to 1971, while the assets later acquired in the Timan-Pechora Basin had a history dating to 1988. The company’s business was organized around two principal operating groupings, commonly identified as Exillon TP for the Timan-Pechora assets and Exillon WS for the West Siberian assets. The portfolio comprised ten oil fields described as being at early stages of development. This positioned Exillon as an upstream exploration and production business rather than a downstream fuel retailer, refiner, or integrated energy conglomerate. Its commercial focus was the appraisal, development, and eventual production of crude oil from existing Russian licenses and fields. Exillon expanded its asset base shortly after formation by acquiring interests in the Timan-Pechora Basin, complementing the West Siberian properties acquired at the company’s creation. The two regions are significant Russian hydrocarbon provinces, but the company’s documented portfolio remained comparatively concentrated and centered on early-development fields. Public descriptions of the business emphasize resource ownership and development potential rather than a broad international operating footprint. Exillon Energy became a public company when it was admitted to trading on the London Stock Exchange in December 2009. Its London listing provided a public-market structure for an enterprise whose underlying operations were located in Russia. In 2013, Russian businessman Alexey Khotin acquired a 30% stake in the company, marking a notable change in its shareholder profile. The available reference material does not establish that Khotin served as an executive or that he became the sole owner. The company remained listed in London until December 2020, when it was delisted. The supplied reference material does not specify the reason for the delisting, the company’s subsequent ownership structure, its production levels, financial performance, or whether all of its operating activities continued afterward. Accordingly, Exillon Energy’s present operating status should be treated as unclear. Its documented identity remains that of a Russian upstream oil company with assets in Western Siberia and Timan-Pechora, rather than a consumer-facing energy brand.

History

Exillon Energy was created in January 2009 by Maksat Arip, a businessman from Kazakhstan. Its initial business was based on oil assets in Russia’s West Siberia region. Those properties had an exploration history reaching back to 1971, meaning that the company inherited a portfolio with a considerably longer geological and licensing background than its corporate history. Soon after establishment, Exillon added assets in the Timan-Pechora Basin. The acquired properties had an exploration history dating to 1988 and gave the company a second operating center in a major Russian oil-producing region. The resulting portfolio was generally described through two operating groupings: Exillon WS, representing the West Siberian activities, and Exillon TP, representing the Timan-Pechora activities. The company’s documented asset base consisted of ten oil fields at early stages of development. Its role was therefore concentrated in upstream petroleum work, including the exploration, appraisal, and development of oil resources. The available reference material does not provide production figures, reserves, revenue, or details of individual field names, and those items cannot be reliably added to this profile. Exillon pursued a public-market strategy soon after formation. It was listed on the London Stock Exchange in December 2009, giving investors access to a company whose operating properties were located in Russia. In 2013, Russian businessman Alexey Khotin acquired a 30% stake. The available account identifies him as a significant shareholder but does not establish an executive position or describe the full ownership structure following the transaction. Exillon remained publicly traded in London until December 2020, when it was delisted. The supplied sources do not state why the delisting occurred or provide a detailed account of the company’s post-listing structure. They also do not establish whether the business continued operating under the same name, whether its assets were transferred, or whether production and development activities were materially expanded after delisting. Exillon Energy’s present status is therefore recorded as unknown. Historically, the company is best understood as a focused Russian upstream oil enterprise. Its distinguishing characteristics were its concentration in Western Siberia and Timan-Pechora, its portfolio of early-development oil fields, its creation and expansion in 2009, and its relatively short period as a London-listed company.
