What is the term for the process of adding new wells in an existing field within the original well patterns to accelerate recovery or to test recovery methods?

• A. Horizontal Drilling
• B. Recompletion
• C. Infill Drilling
• D. Expansion Drilling

Answer: (C)

Infill drilling is drilling new wells inside an already developed field pattern to accelerate recovery and to test recovery methods. The idea is to increase the density of wells within the original field so you can access portions of the reservoir that are left unrecovered between existing wells, improving sweep efficiency and making it easier to evaluate or implement enhanced oil recovery pilots. This approach is common in mature fields where there’s room between wells to place producers or injectors, helping to manage pressure and boost overall recovery. Other terms describe different ideas: horizontal drilling refers to the shape of the wellbore rather than adding new wells within the field, and recompletion means re-entering an existing well to produce from a new zone. Expansion drilling implies extending beyond the current field pattern, not staying within it.
