Wellbore
A wellbore is the hole drilled into the ground for oil or gas extraction. Think of it like a long tunnel that connects the surface to where oil or gas is located underground. It's a fundamental concept in oil and gas drilling, and professionals work to design, drill, maintain, and optimize these pathways. When you see this term in resumes, it often relates to activities involving the planning, drilling, or maintenance of these underground passages. Other common terms for this are "borehole" or "well," though wellbore is the more technical industry term.
