Well Planning & Design Design the well trajectory (vertical, directional, horizontal) Select drilling methods and equipment Plan casing, cementing, and mud programs Prepare detailed drilling programs 2. Cost Estimation & Budgeting Estimate total drilling cost (rig, materials, manpower) Optimize operations to reduce cost without compromising safety Track daily expenses vs budget 3. Operations Supervision Work closely with rig teams and contractors Monitor drilling progress in real time Ensure operations follow the plan 4. Safety & Risk Management Identify hazards (blowouts, kicks, equipment failure) Ensure compliance with safety standards Work with HSE teams to minimize risks 5. Problem Solving (Critical Part) Handle issues like: Stuck pipe Lost circulation Well control incidents Make quick technical decisions under pressure 6. Coordination & Communication Coordinate with: Geologists Reservoir engineers Rig crew Service companies (mud logging, cementing, logging tools) Report daily progress to management

Problem-solving & decision-making Knowledge of drilling software (like Landmark, WellPlan) Good communication & teamwork Ability to work under pressure (very important)
