What Master's courses in Germany would best suit my BTech in Petroleum, Oil and Gas, and Diesel Technology, given my interest in petroleum, energy systems, or process engineering?

Your BTech gives you three genuinely different directions in Germany: stay close to petroleum engineering itself, pivot toward the wider energy transition, or move into process and chemical engineering, and each one has a specific program built for it rather than a generic fit.

Comparing the Three Directions

Why Clausthal Is the Direct Match

Clausthal's petroleum engineering masters is explicitly built on a petroleum engineering or equivalent bachelor's background, and its current specializations in reservoir management, drilling and production, and deep geothermal systems mean your existing degree does not need to be reinterpreted for admissions, only translated into their module equivalency check.

What to Check Before You Apply to Process Engineering

A petroleum degree is not automatically treated as equivalent to a chemical or process engineering bachelor's, so before applying to programs at Technical University of Berlin or Hamburg University of Technology's process engineering track, compare your BTech's actual credit hours in thermodynamics, fluid mechanics, and process calculations against each program's listed prerequisite modules.

My Advice

If petroleum itself is your genuine first interest, apply to Clausthal first, since it is the only program here that treats your exact BTech as a natural prerequisite rather than a borderline case. Keep the geothermal and subsurface energy storage specializations within that same Clausthal program as your backup direction if pure oil and gas hiring feels thin by the time you graduate.
