penta capstone semester 1
TRANSCRIPT
Goals and Objectives
• Discretize and map the given formations
• Analyze log data
• Calculate expected recoverable oil in place
• Recommend further action with the field
Findings
• Based upon the data:
• 100 - 270 Million Barrels
• 100 Dollar per Barrel comes out 10 – 27 Billion Dollars
• Further develop the selected area
Geological Structure
• Penta Alpha was formed in the early cretaceous period
• Predict the ability to produce oil• Types of lithology• Limestone , sandstone, and minimal shale deposits
• Types of obstacles • Drilling Break, and kick
• Pay zone rocks• Sandstone
Discretization Process
• Analyzing contour map
• Drawing grids
• Construct surface map
• Surface Map of Penta Alpha Formation
Evaluating Well logs
• Establish cut-offs• Water saturation < .7 or 70%• Gamma ray < 40 API • Resistivity > 10 ohm-meters
• Determine Net Pay
Well log data gathering
• From porosity, water saturation and net pay thickness
• Determine maximum, minimum and average values
• Three distribution maps of porosity, water saturation and net pay thickness
Monte Carlo Stimulation
• Calculate Values within set ranges for: • Recovery Factor of 0.2 to 0.4 • Formation Volume Factor of 1.05 – 1.08
• Calculated OOIP ranged • 375 – 675 million barrels
• Calculated recoverable oil • 100 – 270 million barrels
Area of Interest
• Determine the areas with higher barrels per acres from recoverable oil in place
• P50 stimulation • area of 3643 acres and produce around 34 million barrels.
• P90 stimulation• area of 3643 acres and produces around 18.5 million barrels
Conclusion• Valued at approximately 10 – 27 billion US Dollars
• A well drilled every 640 acres should be suitable in this situation
• Potential revenue should be attributed to a water saturation cut off of 70%
• Recommend entering phase two of drilling and preparing wells for production
