Industry Leaders

From the beginning, Meridian Energy Group was founded on the guiding principle that clean is better. Following through on its promise, the Davis Refinery, outside Belfield in Billings County, will be the cleanest refinery ever built. The Meridian team, which now includes Basic Equipment, Axens North America and Vepica USA along with SEH engineering and ZIA Engineering & Environmental Consultants are hard at work designing what will be a model of efficiency, low emissions and technological advancement. Every element of Davis is being designed to operate in the cleanest, most efficient, most environmentally compliant manner, meeting and exceeding Federal Class 1 Air Quality Standards.


Axens is an international provider of technologies (process licenses), products (catalysts and adsorbents) and services (technical assistance, training, consulting) to the refining, petrochemical, gas and alternative fuels markets, and backed by nearly fifty years of R&D and industrial success. Our strong position in petroleum refining covers virtually every area from liquefied petroleum gas sweetening through to vacuum residue conversion and includes commercially proven solutions for clean fuels production. We deliver complete basic engineering design packages to our customers, including HAZOP studies, detailed engineering reviews and more.

BASIC Equipment
BASIC Equipment

Founded in 1991, BASIC is a fully integrated design, construction and logistics frim serving the oil and gas, refining, petrochemical and specialty process industries worldwide. Structured to fill a unique role for its clients, BASIC is large enough to offer a full range of services, yet small enough to ensure that every project receives the personal attention it deserves. Locally owned since 1991 and still operated by the original founders. BASIC has been fabricating process equipment and pressure vessels under the ASME code standards ever since. BASIC can take the most complex project, and make it ‘BASIC’.
