Transcribed Image Text:**Drillstring and Mud Pump Specifications for Educational Engagement**
For the following five questions, consider the specified details for a drillstring composed solely of drillpipes (DP) and a bit:
**Drillstring:**
- **DP Outer Diameter (OD):** 5 inches
- **DP Inner Diameter (ID):** 4.2 inches
- **DP Stand Length:** 90 feet
**Mud Pump:**
- **Type:** Triplex, single acting
- **Liner Diameter:** 6.5 inches
- **Stroke Length:** 12 inches
- **Volumetric Efficiency:** 95%
- **Flow Rate:** 400 gallons per minute (gpm)
**Well:**
- **Depth (Measured):** 12,000 feet
- **Hole Size:** 9 inches
This information is essential for understanding the technical specifications and operations associated with drilling equipment in oil and gas explorations. These parameters guide the design and optimization of the drilling process.
![### Educational Exercise: Understanding Pumping Strokes in Drilling Operations
In this exercise, students will explore the mechanics of drilling fluids and the required pump strokes for efficient drilling operations. Each question is designed to enhance understanding of fluid dynamics in a drilling context.
#### Question A
**Prompt:**
How many strokes are required to pump from surface to bit?
**Input Box:**
[_______]
---
#### Question B
**Prompt:**
How many strokes are required to pump from bit to surface?
**Input Box:**
[_______]
---
#### Question C
**Prompt:**
How many strokes are required to fill up the hole after 10 stands being pulled dry?
**Input Box:**
[_______]
---
Students are encouraged to consider factors such as the volume of the drill pipe, the annulus space, and the overall length of the pipe in calculating the number of strokes. This practical exercise aids in reinforcing the theoretical concepts of fluid displacement and pressure management crucial in drilling operations.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fcc2304c8-1974-4b4c-9b89-46bbcd5de840%2Faf903fc9-7b9f-454d-b140-3de80094ecf7%2Fh1ea2sq_processed.jpeg&w=3840&q=75)
