L04-I

Project Overview

• Project Name: L04-I Oil Project
• Location: Include geographical coordinates, country, and region.
• Project Type: Whether it is an onshore or offshore project.
• Project Phase: Current stage of the project (exploration, development, production).

Well Data

• Well Locations: Coordinates and descriptions of each well.
• Well Types: Whether the wells are oil, gas, or a combination of both.
• Directional Survey Data: Detailed survey data including depth, azimuth, and inclination.

Reservoir and Formation Data

• Reservoir Properties: Porosity, permeability, saturation, and other relevant reservoir characteristics.
• Formation Data: Details about the geological formations involved, including rock types and fluid properties.

Production Model

• Multiphase Flow: Use models like PROMOD1 to describe complex multiphase flow in the reservoir, wellbore, choke, and surface pipelines. This includes using equations such as Fetkovich's for gas reservoirs and Vogel's or PI equations for oil reservoirs. Additionally, use multiphase flow equations like Beggs-Brill, Hagedorn-Brown, Hasan-Kabir, and Duns and Ros for wellbores and pipelines.
• Inflow/Outflow Performance Curves: Generate curves based on bottom-hole or wellhead nodes to determine production rates and pressures.
• Gas Lift: If applicable, include details on gas lift operations, including injection depth and rates.

Tubular and Surface Equipment

• Tubing and Casing Data: Length, inner diameter (ID), outer diameter (OD), and material properties of the tubing and casing strings.
• Surface Line Data: Length, ID, and any deviations of the surface pipelines.
• Choke Size: Specifications of the choke used to control flow rates.
• Perforation Depths: Details on the perforated intervals of the well.

Parameter Data

• Well Type: Whether it is an oil or gas well.
• Rate Data: Historical and projected production rates.
• Fluid Properties: Oil and gas properties, including API gravity, viscosity, and gas-oil ratio.
• Temperature Data: Temperature profiles along the wellbore and surface lines.
• Productivity Data: Productivity index (PI) and other relevant productivity metrics.
• Gas Lift Data: If applicable, include gas lift rates, pressures, and other operational parameters.

Input Data Files

• Well Data File: Company and project name, well locations, date, and comments.
• Survey Data File: Directional survey data.
• Tubular Data File: Tubing and casing string details.
• Parameter Data File: Well type, rate data, fluid properties, temperature data, productivity data, and gas lift data.
• Project Data File: Stores the names of the other files and the units used (e.g., English system of units).

Monitoring and Control

• Oil/Water Interface Profiling: Use tools like the 4100-PRO Oil Water Profiler to continuously monitor the oil/water interface and emulsions in tanks, which can help in flow control and chemical injection.

Operational Considerations

• Maintenance and Safety: Include protocols for regular maintenance, such as oil changes, and safety guidelines.
• Environmental Impact: Assess and mitigate any environmental impacts associated with the project.

Economic and Regulatory

• Economic Analysis: Include cost estimates, revenue projections, and economic viability studies.
• Regulatory Compliance: Ensure compliance with local and international regulations regarding oil production.
