Instructions: Choose the best answer for each question.
1. What does "Logged Depth" primarily refer to?
a) The distance between the surface and the deepest point of the wellbore. b) The vertical distance along the wellbore where a specific measurement is taken. c) The total distance measured along the wellbore's actual path. d) The depth at which hydrocarbons are discovered.
b) The vertical distance along the wellbore where a specific measurement is taken.
2. Which depth measurement is crucial for planning drilling operations and assessing the extent of exploration?
a) Logged Depth b) Total Depth c) Measured Depth d) All of the above
b) Total Depth
3. Measured Depth is important for all of the following EXCEPT:
a) Calculating drilling distances. b) Navigating the wellbore. c) Interpreting geological data. d) Determining the exact location of hydrocarbons.
d) Determining the exact location of hydrocarbons.
4. Which statement accurately describes the relationship between Logged Depth and Measured Depth?
a) Logged Depth is always equal to Measured Depth. b) Logged Depth is a subset of Measured Depth. c) Measured Depth is a subset of Logged Depth. d) They are independent measurements.
b) Logged Depth is a subset of Measured Depth.
5. Why is accurate depth measurement important in the oil and gas industry?
a) It helps predict future oil and gas prices. b) It is required by government regulations. c) It allows for efficient drilling, geological interpretation, and resource estimation. d) It helps determine the age of geological formations.
c) It allows for efficient drilling, geological interpretation, and resource estimation.
Scenario:
A drilling crew is working on a well. They have reached a depth of 3,000 feet (ft) measured depth (MD). They then take a logging measurement at that point. The logging measurement indicates that the formation they are interested in is located at a depth of 2,950 feet (ft) logged depth (LD).
Task:
1. **Difference between MD and LD:** The measured depth (MD) of 3,000 ft represents the total distance traveled along the wellbore's actual path. This includes any curves or deviations from a vertical trajectory. The logged depth (LD) of 2,950 ft represents the vertical distance from the surface to the point where the logging measurement was taken. The difference highlights that the wellbore is not perfectly vertical but has some deviations. 2. **Vertical Distance:** The vertical distance between the surface and the formation of interest is the logged depth (LD), which is **2,950 feet**. Even though the wellbore has traveled 3,000 feet measured depth, the actual vertical depth of the formation is 2,950 feet.
