Instructions: Imagine you are a drilling engineer reviewing a wellbore diagram. The diagram shows a well that is drilled vertically for 1000 meters, then deviates horizontally for another 500 meters. The wellbore intersects a reservoir at 1300 meters depth.
Task:
* **Total length of the well:** 1500 meters (1000 meters vertical + 500 meters horizontal). * **Depth of the casing shoe:** It is impossible to determine without further information. The casing shoe depth could be anywhere below the surface, but it should be at least deep enough to protect the well from potential surface contamination. * **Depth of the top of the reservoir:** 1300 meters. * **Well completion method:** Given the presence of a reservoir at 1300 meters and the well's deviation, it's likely that a **cased-hole completion** method is used. This method involves running casing to the desired depth, perforating the casing, and installing production tubing to access the reservoir. This method ensures greater control over the wellbore and allows for efficient production from the targeted zone.
