Le forage directionnel, un élément clé de l'exploration et de la production modernes de pétrole et de gaz, implique **le forage du puits selon un angle de déviation ou une trajectoire planifiés**. Cela permet aux puits d'atteindre des formations cibles qui ne se trouvent pas directement sous le derrick de forage, offrant de nombreux avantages par rapport au forage vertical rectiligne.

Scenario: An oil company wants to access a reservoir located beneath a large lake. They plan to use directional drilling to reach the reservoir from a drilling platform on the lake's shore.
Task:
**1. Suitable Type of Directional Drilling:** The most suitable type of directional drilling for this scenario would be **slant drilling**. This is because the reservoir is located beneath a lake, requiring the wellbore to be drilled at a specific angle to reach the target formation. **2. Potential Challenges:** * **Wellbore stability:** Drilling through the lakebed could create instability issues, potentially leading to wellbore collapse or fluid losses. * **Environmental impact:** Drilling operations in a lake environment raise concerns about potential water pollution or disruption of aquatic ecosystems. **3. Technological Solution:** To address the challenge of wellbore stability, the company could use **advanced drilling fluids**. These fluids are specifically designed to provide better wellbore support, prevent fluid losses, and minimize the risk of collapse. These fluids can also be formulated to minimize environmental impact by reducing the risk of contamination.
