Stretching in Oil & Gas Resource Scheduling: A Flexible Approach to Project Optimization

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?

  • Optimized Completion Dates: By stretching activities, project managers can potentially achieve an earlier project finish date without compromising overall resource allocation.
  • Resource Leveling: Stretching helps distribute resources more evenly across the project timeline, mitigating potential bottlenecks and ensuring a smoother workflow.
  • Flexibility in Response to Delays: If unforeseen delays occur, stretching can help adjust the schedule and minimize their impact on the overall project timeline.

How Stretching Works

The process of stretching an activity involves:

  1. Identifying the Activity: Select the activity you wish to stretch, considering its potential impact on the overall project timeline.
  2. Determining the Stretch Factor: Calculate the desired increase in the activity's duration. This factor will directly affect the reduction in resource intensity.
  3. Adjusting the Profile: The resource intensity of the activity is proportionally reduced to reflect the increased duration. For example, if you double the duration, the resource requirement is halved.

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

  • Activity Suitability: Stretching is not suitable for every activity. Activities with strict deadlines or those requiring constant resource utilization might not benefit from this approach.
  • Resource Availability: Ensure that the required resources are available for the extended duration of the activity.
  • Potential Impacts: Evaluate the potential impact of stretching on other project activities and dependencies.

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.

Exercise: Stretching for Optimization

Scenario:

You are managing a project to install a new pipeline for an oil and gas company. The initial schedule allocates 10 days for welding the pipeline sections, requiring a crew of 8 welders.

Task:

Using the concept of stretching, propose a revised schedule for the welding activity that:

  • Extends the duration to 15 days.
  • Reduces the number of welders required.
  • Considers potential resource availability and project dependencies.

Explain your reasoning and any potential implications of this approach.

Exercice Correction

**Revised Schedule:**

  • Duration: 15 days (extended from 10 days)
  • Welders: 5 (reduced from 8)

Reasoning:

  • By stretching the welding activity, we can reduce the required number of welders by 3.
  • This can potentially save on labor costs and offer flexibility in resource allocation.
  • The extended duration might require adjustments to the overall project timeline, which should be carefully considered.

Potential Implications:

  • Project Timeline: The extended duration for welding might push back the overall project completion date.
  • Resource Availability: Ensure that the required 5 welders are available throughout the extended duration.
  • Dependencies: Analyze any dependencies on the welding activity and how the extended duration might affect downstream tasks.
  • Quality Control: With a smaller crew, it is essential to implement robust quality control procedures to ensure the welds are performed to the required standards.

Conclusion:

Stretching the welding activity provides a potential solution to optimize resource allocation, but a careful analysis of potential impacts on the project timeline and other dependencies is essential.
