In the complex world of oil and gas projects, effective project management relies on robust planning and organization. Subnetworks play a crucial role in this process, enabling the division of large, intricate projects into manageable, interconnected units.
What is a Subnetwork?
A subnetwork, in the context of oil and gas projects, refers to a section of the project that requires its own dedicated network diagram. It's essentially a "sub-project" within the larger project, focusing on a specific activity or a cluster of related activities. These subnetworks are typically represented as single activities within the main project network.
Why Use Subnetworks?
Subnetworks offer several benefits for managing oil and gas projects:
Example: Subnetworks in a Well Drilling Project
Consider a well drilling project. The overall project network might include activities like site preparation, drilling rig installation, drilling operations, and well completion. Each of these major activities could be represented as a subnetwork:
Conclusion
Subnetworks are valuable tools for project managers in the oil and gas industry, enabling them to effectively manage complexity, enhance planning, and promote collaboration. By leveraging subnetworks, project teams can gain a clearer understanding of individual project components, optimize resource allocation, and ensure successful project execution.

This document expands on the concept of subnetworks in oil & gas projects, breaking down the topic into key areas: Techniques, Models, Software, Best Practices, and Case Studies.
Chapter 1: Techniques for Implementing Subnetworks
Subnetworks are implemented through a breakdown of the overall project into smaller, more manageable units. Several techniques facilitate this decomposition:
Work Breakdown Structure (WBS): The WBS is a fundamental technique for decomposing a project into smaller, more manageable components. In the context of subnetworks, each element of the WBS can represent a potential subnetwork, allowing for a hierarchical structure reflecting the project's complexity. A detailed WBS ensures that all aspects of the subnetwork are accounted for.
Critical Path Method (CPM) and Program Evaluation and Review Technique (PERT): These scheduling techniques are crucial for identifying the critical path within each subnetwork. By analyzing the dependencies and durations of activities within each subnetwork, project managers can optimize scheduling and resource allocation. This helps identify potential bottlenecks and allows for proactive mitigation.
Decomposition by Discipline: Subnetworks can be defined based on engineering disciplines (e.g., drilling engineering, reservoir engineering, process engineering). This approach fosters specialized expertise and facilitates efficient collaboration within dedicated teams.
Decomposition by Geographical Location: For geographically dispersed projects, subnetworks can be created based on location (e.g., onshore vs. offshore operations, different well sites). This helps address logistical challenges and ensures appropriate resource allocation for each location.
Decomposition by Phase: Projects often proceed through distinct phases (e.g., design, construction, commissioning). Each phase can be treated as a subnetwork, simplifying planning and facilitating progress tracking.
Chapter 2: Models for Representing Subnetworks
Several models can effectively represent subnetworks within the overall project:
Hierarchical Network Diagrams: These diagrams illustrate the relationship between the main project network and its constituent subnetworks. The main project displays subnetworks as high-level activities, while each subnetwork possesses its own detailed network diagram.
Gantt Charts: Gantt charts provide a visual representation of the schedule for each subnetwork, displaying tasks, durations, dependencies, and milestones. This facilitates monitoring progress and identifying potential scheduling conflicts.
Precedence Diagramming Method (PDM): PDM is used to illustrate the logical relationships between activities within each subnetwork. This method helps in identifying dependencies and critical paths.
Resource Allocation Models: These models help optimize resource allocation across different subnetworks, ensuring that resources are efficiently distributed to meet the project's overall timeline and budget. They consider resource limitations and potential conflicts.
Chapter 3: Software for Managing Subnetworks
Several software tools facilitate the management and analysis of subnetworks:
Project Management Software (e.g., Primavera P6, MS Project): These tools offer functionalities for creating and managing WBS, developing network diagrams, scheduling activities, tracking progress, and managing resources across subnetworks.
Simulation Software (e.g., Arena, AnyLogic): These tools allow for the simulation of different scenarios and the analysis of the impact of various factors on project schedules and resource allocation within subnetworks.
Data Analytics Tools (e.g., Power BI, Tableau): These tools can be used to visualize data from different subnetworks, providing insights into project performance and facilitating informed decision-making.
Chapter 4: Best Practices for Subnetwork Management
Effective subnetwork management requires adherence to several best practices:
Clear Definition of Subnetworks: Each subnetwork should have clearly defined scope, objectives, deliverables, and responsibilities.
Effective Communication: Maintaining clear communication between teams working on different subnetworks is crucial for ensuring coordination and preventing conflicts.
Regular Monitoring and Control: Progress within each subnetwork should be regularly monitored and controlled to identify potential issues early on.
Risk Management: Risks specific to each subnetwork should be identified and mitigated proactively.
Integration Management: Ensuring seamless integration between different subnetworks is critical for successful project completion.
Chapter 5: Case Studies of Subnetwork Implementation
(This section requires specific examples. Below are potential case study outlines. Real-world examples with data would significantly strengthen this section.)
Case Study 1: Offshore Platform Construction: Discuss how subnetworks were used to manage the various phases of an offshore platform construction project (e.g., foundation installation, module fabrication and integration, commissioning). Highlight the challenges and successes.
Case Study 2: Onshore Pipeline Project: Describe the use of subnetworks to manage different segments of a large onshore pipeline project, considering geographical location and potential environmental impacts. Show how resource allocation was managed across subnetworks.
Case Study 3: Enhanced Oil Recovery (EOR) Project: Detail how subnetworks were employed in a complex EOR project, focusing on the management of different injection and production wells, and the integration of different technologies.
By implementing the techniques, leveraging appropriate models and software, and adhering to best practices, oil and gas project managers can effectively utilize subnetworks to improve planning, collaboration, and ultimately, project success. The case studies will provide concrete examples of successful subnetwork implementation in diverse project scenarios.
