• Serve as the on-site fluids authority for the operator and rig team, executing and adjusting the mud program by hole section as drilling conditions change.
• Conduct routine mud checks for density, rheology, gel strengths, fluid loss, pH, chlorides, solids, MBT, and oil/water ratio as applicable.
• Treat the active system with appropriate additives such as barite, bentonite, polymers, inhibitors, LCM, and others.
• Manage hydraulics and ECD, oversee solids-control equipment, and diagnose contamination issues (cement, salt, drilled solids, H2S/CO2).
• Support well-control readiness through correct mud weight and gas-handling practices.
• Manage product inventory and logistics, document fluid performance, and brief the company man, toolpusher, and drilling supervisor on trends, costs, and recommended treatments.
• Travel frequently to different wellsites, including onshore pads, remote basins, and offshore or international locations as assigned.

• Perform physically demanding tasks, including 12-hour field shifts, climbing stairs and ladders, working in confined spaces and outdoor weather, and handling chemicals and equipment.

Requirements

• Bachelor's degree in chemical, petroleum, or a related engineering discipline, or equivalent petroleum-technology training with proven fluids-school and rig experience.
• Hands-on experience as a mud engineer or drilling-fluids technician on active wells.
• Working knowledge of water-based, oil-based/synthetic, and brine fluid systems.
• Current or readily obtainable credentials such as IADC WellCAP or IWCF well control, H2S, First Aid/CPR, and any regional survival or site tickets required for assignment (e.g., HUET/BOSIET, TWIC).
• Ability to pass industry medical, drug and alcohol, and site-access screening.
• Physically fit for field work, including extended shifts and manual handling.
• Strong written reporting skills and the ability to communicate clearly with rig and operator teams.
• Calm problem-solving skills under pressure and the ability to represent the service company professionally.
• Willingness and ability to travel frequently and mobilize on short notice across the Americas.
