What Mud Engineers Actually Earn

How much do mud engineers make in 2026?

Mud engineers, also called drilling fluids engineers or fluids specialists, are classified here inside SOC 17-2171, petroleum engineers, which BLS OEWS May 2025 puts at a national median of $144,910 a year, or $69.67 an hour, with a P10 to P90 range of $81,440 to $253,200 across 18,060 workers. That is a broad match and the disclosure is important, because the pooled code is dominated by degreed petroleum engineers in operator and consultancy offices, while mud engineering is a field-based service role. Entry does not always require a petroleum engineering degree: many mud engineers come from chemistry, geology or other science backgrounds and are trained by the fluids service provider, and field mud engineers realistically sit in the lower part of this published band rather than at its median. The work itself is technical and continuous: monitoring drilling fluid properties on the rig, adjusting the system to maintain density, rheology and filtration within programme, managing solids control and troubleshooting hole problems. Rotational schedules, per diem and travel arrangements apply as elsewhere in the field, and those amounts are employer-specific and outside the BLS wage series. BLS projects 1.3% growth through 2034 with roughly 1,200 openings a year. → Full mud engineer career guide, career path, credentials & placement →

Published (BLS): BLS OEWS May 2025, SOC 17-2171, United States national estimate. Public, methodologically rigorous, but sampled on a rolling 3-year basis and published ~10 months after collection — so it reflects wages that are already 1–2 years old by the time you read them.

Level and certification medians: distributed across the published BLS percentile range for this SOC code (P10 through P90) according to the credential tiers this occupation actually hires at. They are modeled reference points, not separately surveyed wages.

State and metro figures: modeled — the BLS national median multiplied by the GlobalCybers state wage index, and for metros by the published metro index for that state. They are estimates of local pay, not BLS state or metropolitan-area observations, and are labelled as modeled in the tables below.

No verified placement sample:GlobalCybers does not yet publish a placement median for this role, so no "verified" figure appears anywhere on this page.
