WEP’s History

Well Engineering Partners (WEP) is established in 1996 as an engineering company for oil, gas and salt wells. At the first start, WEP was a small company with a few employees. The company grew with its focus on oil, gas and salt wells worldwide. From 2006 on WEP’s focus was more on the engineering and drilling of geothermal wells in the Netherlands. Nowadays WEP has its hands in Oil&Gas, Solution Mining & Geothermal Energy.

In 2011 WEP merged with PGMi (PetroGas Minerals international B.V.), PGMi was a similar company as WEP with its main focus on engineering geothermal wells as well. PGMi started in 2006 with the Heerlen Minewater project and engineered and managed 3 more geothermal projects. After the merger, WEP became a company with 25 engineers and grew rapidly. In the years from 2011 on, WEP became the leading company in engineering geothermal wells in the Netherlands. Furthermore, WEP strengthened its position in the engineering, drilling and maintenance services in the salt industry in the Netherlands.

Nowadays WEP is an engineering company with 30 engineers and an extensive network of associated consultants. WEP has a great reputation for excellence in projects.
