In the high-stakes world of oil and gas project management, optimizing resource allocation and project timelines is crucial. Resource scheduling software plays a vital role, enabling project managers to efficiently plan and track activities. One powerful feature within these tools is the ability to "stretch" activities, a concept that offers flexibility and potential for improved project outcomes.
What is Stretching?
Stretching, in the context of oil & gas resource scheduling, refers to the ability to extend the duration of an activity while proportionally reducing its resource intensity. This approach allows for a more adaptable scheduling strategy, particularly when faced with resource constraints or unexpected delays.
Why is Stretching Useful?
How Stretching Works
The process of stretching an activity involves:
Example Scenario
Imagine an oil and gas project involving drilling operations. The initial schedule allocates 10 days for drilling a specific well, requiring a crew of 5 engineers. Stretching this activity to 15 days could allow for a smaller crew of 3 engineers, while still achieving the desired outcome. This approach potentially saves on labor costs and provides flexibility in crew allocation.
Considerations for Effective Stretching
Conclusion
Stretching offers a valuable tool for oil and gas project managers to optimize resource allocation and achieve desired project outcomes. By strategically extending activity durations and adjusting resource intensity, stretching can help navigate challenges, enhance flexibility, and ultimately contribute to successful project completion. Utilizing this feature effectively requires careful analysis and consideration of its impact on the project as a whole.

Chapter 1: Techniques
Stretching in oil & gas resource scheduling involves extending the duration of an activity while proportionally reducing its resource intensity. This contrasts with simply delaying an activity, which maintains the same resource requirements. Several techniques can facilitate stretching:
Linear Stretching: The most straightforward approach. The activity's duration is increased linearly, and the resource requirement is reduced proportionally. If the duration is doubled, the resource requirement is halved. This method is easily implemented in most scheduling software.
Non-Linear Stretching: This approach allows for more nuanced adjustments to the activity's resource profile. The reduction in resource intensity may not be directly proportional to the increase in duration. For instance, an activity might initially require a large workforce, which can be gradually reduced as the project progresses, even though the total duration increases. This is useful when some tasks can be completed with a smaller team after initial setup.
Resource Leveling with Stretching: This combines resource leveling techniques with stretching. Resource leveling aims to smooth out resource utilization across the project. Stretching aids in this process by providing the flexibility to extend the duration of over-allocated activities, reducing peaks in resource demand.
Critical Path Method (CPM) with Stretching: Stretching can be strategically applied to activities on the critical path (the sequence of activities determining the shortest project duration). Stretching non-critical activities can free up resources, potentially accelerating the critical path. However, careful analysis is needed to avoid unintended consequences.
Chapter 2: Models
Several scheduling models can incorporate stretching:
Linear Programming (LP): LP models can optimize resource allocation by considering activity durations and resource requirements. By introducing variables representing the stretching factor, LP can find the optimal combination of activity durations and resource allocation that minimizes project completion time or cost.
Simulation Models: Monte Carlo simulation or other simulation techniques can be used to evaluate the impact of stretching on project completion time and resource utilization under various scenarios, incorporating uncertainty in activity durations and resource availability. This allows for risk assessment related to the stretching strategy.
Heuristic Models: Heuristic approaches provide approximate solutions to complex scheduling problems. These models can incorporate stretching rules and criteria to create feasible schedules. They're useful when exact optimization is computationally expensive.
Chapter 3: Software
Various project management and resource scheduling software packages incorporate stretching capabilities, either directly or indirectly:
Primavera P6: A widely used software in the oil & gas industry, Primavera P6 offers features for resource leveling and adjustment of activity durations, effectively enabling stretching.
Microsoft Project: While not as specialized as Primavera P6, Microsoft Project also provides the tools to manipulate activity durations and resource assignments, allowing for stretching techniques.
Custom-Developed Software: Some oil & gas companies utilize custom-developed software tailored to their specific project needs, which may include advanced algorithms for resource optimization and stretching capabilities.
The specific implementation of stretching differs across software, requiring familiarity with the individual tool's features and functionalities. The choice of software depends on the project's complexity, budget, and specific requirements.
Chapter 4: Best Practices
Effective utilization of stretching requires careful planning and consideration:
Identify Suitable Activities: Not all activities are suitable for stretching. Activities with strict deadlines, critical dependencies, or those requiring constant resource attention should be carefully evaluated before stretching.
Realistic Stretch Factors: Over-stretching can lead to prolonged project durations and increased costs. The stretch factor should be determined based on a thorough analysis of the activity's requirements and resource availability.
Impact Analysis: Before implementing any stretching strategy, assess its potential impact on other activities, dependencies, and resource allocation across the entire project.
Contingency Planning: Unforeseen delays or resource issues may necessitate further adjustments. Develop contingency plans to address potential challenges and maintain project flexibility.
Collaboration and Communication: Keep stakeholders informed of any stretching decisions and their implications. Effective communication is vital for successful project management.
Chapter 5: Case Studies
(This section would include real-world examples demonstrating the successful application of stretching in oil & gas resource scheduling. Details would depend on the availability of specific projects and data. Examples could include: )
Case Study 1: Optimizing Offshore Platform Construction: Illustrating how stretching reduced resource peaks during critical phases, leading to cost savings and on-time completion.
Case Study 2: Improving Pipeline Installation Efficiency: Showing how stretching helped accommodate unexpected delays without compromising the overall project schedule.
Case Study 3: Accelerated Drilling Program: Describing a scenario where stretching certain drilling activities enabled faster completion of the overall program despite resource constraints.
Each case study should highlight the specific techniques used, the challenges encountered, and the benefits achieved through the strategic application of stretching. Quantifiable results (e.g., cost savings, time reduction, improved resource utilization) should be presented whenever possible.
