L10-P

Project Overview

• Project Name: L10-P Oil Project
• Location: Specify the geographical location of the project, which could be onshore or offshore.
• Operator: Identify the company or consortium operating the project.

Field Production Profile

• Production Phases: The production profile typically includes three phases: buildup, plateau, and decline.
  • Buildup Phase: Define the period and rate at which production increases to reach the plateau rate. This includes the initial production rates and the time it takes to reach the peak production rate.
  • Plateau Phase: Specify the duration and production rate during this stable period.
  • Decline Phase: Outline the rate and duration of the decline in production after the plateau phase.

Recoverable Reserves

• Recoverable Oil: Specify the target ultimate recovery for the field, which is a critical input for calculating the production profile and well requirements.

Well Schedule and Details

• Number of Wells: Determine the required number of production wells, water injection wells, and gas injection wells based on the field production profile and recoverable reserves.
  • Production Wells: Define the well rates for the first and final years, and use linear interpolation to calculate the well rates for each year. Optionally, you can specify a different decline rate for the wells compared to the field decline rate.
  • Water and Gas Injection Wells: Schedule these wells based on the field's gas injection profile. You can model a constant gas injection rate or a rate as a percentage of total production.

Field Development Plan

• Field Area: If applicable, specify the field area to calculate the area per production well, which can be displayed in the main results panel.
• Well Workovers: Plan the frequency of well workovers, such as every 5 years, and track the cumulative number of workovers and their impact on production.

Technical and Operational Details

• Swing Factor: For gas fields, consider the swing factor if the field operates on a summer/winter swing basis.
• Infrastructure: Outline the necessary infrastructure, including pipelines, processing facilities, and storage tanks.
• Environmental and Safety Considerations: Include any environmental impact assessments, safety protocols, and regulatory compliance measures.

Example Using Petroleum Solutions Profile Help

Here is an example of how you might input data into a tool like Petroleum Solutions Profile Help:

• Plateau Duration: 5 years
• Decline Rate: 10% per annum after the plateau phase
• Well Details:
  • First Year Well Rate: 5,000 barrels per day
  • Final Year Well Rate: 2,000 barrels per day
  • Well Decline Rate: Optionally, specify a different decline rate for the wells
• Field Area: 100 square kilometers (optional)
• Well Workovers: Every 5 years
• Gas Injection: Model as a percentage of total production or a constant rate.
