Project Overview

• Project Name: L04-G Oil Project
• Location: Specify the geographical location, including the country, region, and exact coordinates if available.
• Project Type: Oil production project, potentially involving exploration, development, and production phases.
• Operators and Stakeholders: List the companies involved, including the operator, partners, and any regulatory bodies.

Geotechnical and Reservoir Data

• Reservoir Characteristics:
  • Type of reservoir (e.g., sandstone, carbonate)
  • Depth and thickness of the reservoir
  • Porosity, permeability, and saturation data
  • Fluid properties (oil API gravity, gas-oil ratio, etc.).
• Well Data:
  • Well locations and coordinates
  • Well types (vertical, directional, horizontal)
  • Well completion details (casing, tubing, perforations)
  • Directional survey data.

Production Model and Flow Dynamics

• Production Model:
  • Use of multiphase flow models like PROMOD1, which includes Fetkovich's equations for gas flow and Vogel's or PI equations for oil flow.
  • Multiphase flow equations in wellbores and pipelines (e.g., Beggs-Brill, Hagedorn-Brown, Hasan-Kabir, Duns and Ros).
• Flow Dynamics:
  • Pressure profiles along the wellbore
  • Liquid hold-up distribution and gas and liquid velocities
  • Flow regime map along the wellbore
  • Inflow/outflow performance curves based on bottom-hole or wellhead nodes.

Operational Parameters

• Well and Tubular Data:
  • Length, ID, and OD of tubing and casing strings
  • Surface line length, deviation, and ID
  • Choke size and perforation depths
  • Flow path (through tubing or annulus).
• Production Rates and Pressures:
  • Oil and gas production rates
  • Bottom-hole and wellhead pressures
  • Minimum production rate required for continuous removal of liquid from the wellbore.

Economic and Financial Aspects

• Economic Model:
  • Projected revenues and costs
  • Break-even analysis and return on investment (ROI) calculations
  • Sensitivity analysis to various economic parameters (oil price, production rates, etc.).
• Funding and Licensing:
  • Details on funding sources and investment structure
  • Licensing requirements and approvals from regulatory bodies.

Environmental and Safety Considerations
