في الختام:
Kh، حاصل ضرب النفاذية والارتفاع، يمثل معلمة حيوية في استكشاف وإنتاج النفط والغاز. تُسلط قيمته الضوء على قدرة تشكيلات الخزان على التوصيل، مما يؤثر على القرارات المتعلقة بموضع البئر، والتنبؤ بمعدل الإنتاج، ومحاكاة الخزان. من خلال فهم وتفسير Kh، يمكن للمهنيين في الصناعة اتخاذ خيارات مستنيرة لتحسين استخراج الموارد وضمان التنمية المستدامة لحقول النفط والغاز.
Instructions: Choose the best answer for each question.
1. What does Kh represent in the context of oil and gas reservoirs?
a) The permeability of the reservoir rock b) The height of the reservoir layer c) The overall conductivity of the reservoir formation d) The volume of oil and gas in the reservoir
c) The overall conductivity of the reservoir formation
2. What are the units of Kh?
a) Millidarcies (mD) b) Feet (ft) c) Millidarcies per foot (mD/ft) d) Cubic meters (m³)
c) Millidarcies per foot (mD/ft)
3. Why is Kh important for production rate prediction?
a) It indicates the volume of oil and gas in the reservoir b) It determines the ease with which fluids can flow through the reservoir c) It represents the total pressure within the reservoir d) It measures the amount of water present in the reservoir
b) It determines the ease with which fluids can flow through the reservoir
4. Which of the following factors does NOT influence Kh?
a) Permeability of the reservoir rock b) Thickness of the reservoir layer c) Viscosity of the oil or gas d) Porosity of the reservoir rock
c) Viscosity of the oil or gas
5. How can understanding Kh help with well placement optimization?
a) Identifying areas with high Kh values can indicate promising locations for production wells b) It helps determine the best drilling direction for a particular well c) It predicts the lifespan of a well d) It measures the amount of pressure that can be applied during hydraulic fracturing
a) Identifying areas with high Kh values can indicate promising locations for production wells
Scenario:
You are working as a geologist for an oil and gas company. You have been tasked with evaluating two potential well locations in a new reservoir. The following data has been collected:
| Location | Permeability (mD) | Height (ft) | |---|---|---| | Location A | 200 | 50 | | Location B | 100 | 100 |
Task:
Calculate the Kh value for each location and determine which location is more promising for oil and gas production based on the Kh values.
Calculations:
Conclusion:
Both locations have the same Kh value (10,000 mD/ft), indicating they have the same potential for oil and gas production. While this is a simplified example, other factors like reservoir pressure and fluid properties would also need to be considered for a more accurate assessment.
