5. How can TRR help oil and gas companies in their decision-making?
a) To determine the environmental impact of extraction. b) To evaluate investment opportunities and plan production strategies. c) To identify the best drilling locations for maximum yield. d) To predict the exact amount of hydrocarbons that will be extracted.
**b) To evaluate investment opportunities and plan production strategies.**
Scenario:
An oil company is considering investing in a new oil field. They have estimated the Total Resources to be 100 million barrels of oil. However, they need to estimate the Technically Recoverable Resources (TRR) to make a decision.
Task:
Here is a possible breakdown of the exercise: **1. Key Factors influencing TRR:** * **Reservoir characteristics:** Factors like permeability, porosity, and pressure will affect how easily oil can flow. A high permeability and porosity with good pressure will increase the TRR. * **Recovery Technologies:** Advanced technologies like horizontal drilling, hydraulic fracturing, and enhanced oil recovery methods can increase the TRR by accessing more oil reserves. * **Economic Factors:** The price of oil and the cost of extraction will determine the economic viability of recovering the oil. If the oil price is high and the cost of production is low, the TRR will be higher. **2. Explanation of Factors:** * **Reservoir characteristics:** A tight, low-permeability reservoir will make it difficult to extract oil, leading to a lower TRR. Conversely, a reservoir with high permeability and porosity will allow for greater oil flow and increase the TRR. * **Recovery Technologies:** Implementing advanced technologies can unlock previously inaccessible reserves, significantly increasing the TRR. If the company uses basic methods, the TRR will be lower. * **Economic Factors:** A high oil price makes extraction more profitable and encourages the use of advanced technologies, leading to a higher TRR. Conversely, low oil prices or high extraction costs might make recovering some of the oil uneconomical, resulting in a lower TRR. **3. Estimated TRR:** Assuming a 70% recovery rate, the estimated TRR for this oil field is: 100 million barrels (Total Resources) * 0.70 (Recovery Rate) = **70 million barrels**
