Exercise: Splitting a Drilling Operation

Scenario:

A drilling operation is scheduled to take 12 days. The activity "Drilling Well Y" involves 6 days of drilling and 6 days of casing.

Task:

Apply the concept of splitting to this scenario.

1. Split the activity: Divide the "Drilling Well Y" activity into two segments, "Drilling" and "Casing."
2. Re-allocate resources: Assuming the drilling rig is the only critical resource, propose how you would re-allocate it after the drilling phase is complete.
3. Potential benefits: Describe the potential benefits of splitting this activity in terms of resource utilization and project timeline.

Techniques

Splitting in Oil & Gas Resource Scheduling: Maximizing Efficiency Through Flexible Activity Duration

Chapter 1: Techniques

Splitting, in the context of oil and gas resource scheduling, refers to the division of a single activity into multiple, smaller sub-activities. This allows for more granular control over resource allocation and project timelines. Several techniques exist for implementing splitting effectively:

• Time-based Splitting: The simplest approach, dividing an activity based on time intervals (e.g., splitting a 10-day drilling operation into two 5-day segments). This is useful when resource availability changes predictably over time.

• Resource-based Splitting: This technique divides activities based on resource availability or changes in resource requirements. For example, a well completion activity might be split into preparation, execution, and cleanup phases, each requiring different resources and skill sets.

• Milestone-based Splitting: Activities are split at predefined milestones or checkpoints within the activity. This offers better control and allows for easier monitoring of progress and potential issues.

• Dependency-based Splitting: This involves splitting an activity to manage dependencies more effectively. If a subsequent activity is delayed, splitting allows for adjustments without impacting the entire project schedule.

Effective splitting requires careful consideration of the activity's dependencies, resource requirements for each segment, and potential impact on the overall project schedule. The chosen technique should align with the specific project needs and available resources.

Chapter 2: Models

Several scheduling models can benefit from and accommodate splitting techniques:

• Critical Path Method (CPM): Splitting can help refine the critical path by identifying and addressing bottlenecks more precisely. The updated durations of sub-activities after splitting require recalculation of the critical path.

• Program Evaluation and Review Technique (PERT): Similar to CPM, PERT models can incorporate splitting to better estimate activity durations and their associated uncertainties. Splitting allows for more accurate probabilistic modeling of project completion times.

• Resource-Constrained Scheduling: This type of model explicitly considers resource limitations. Splitting is crucial in these models to optimize resource allocation and prevent resource conflicts. Algorithms such as those used in resource leveling can be significantly improved through the strategic application of splitting.

• Linear Programming (LP) Models: Advanced scheduling models based on LP can incorporate splitting as a decision variable, allowing for optimal resource allocation based on defined objectives (e.g., minimizing project duration or maximizing resource utilization).

The selection of the appropriate model depends on the complexity of the project and the level of detail required in the scheduling process.

Chapter 3: Software

Several software packages support activity splitting for resource scheduling in the oil & gas industry. These typically include:

• Dedicated Resource Scheduling Software: Specialized software packages, such as Primavera P6, MS Project, and others, provide features to split activities, visualize resource allocation, and manage dependencies across the split segments. They often offer advanced functionalities such as resource leveling and what-if analysis.

• Integrated Project Management Systems: Some enterprise resource planning (ERP) systems and integrated project management solutions incorporate resource scheduling modules with splitting capabilities.

• Custom-built Software: Companies with highly specific needs might develop custom software solutions that integrate splitting algorithms tailored to their operational requirements.

Selecting the right software depends on factors such as project scale, budget, and integration requirements with existing systems. The software's ability to handle dependencies, visualize schedules, and perform "what-if" analyses is crucial.

Chapter 4: Best Practices

Effective utilization of splitting requires adherence to best practices:

• Define Clear Objectives: Establish clear objectives before splitting activities. This ensures splitting decisions are aligned with project goals (e.g., minimizing project duration, maximizing resource utilization).

• Maintain Data Integrity: Accurately update resource requirements, durations, and dependencies for each split segment. Inconsistent data can lead to inaccurate scheduling and resource allocation.

• Regular Monitoring and Review: Continuously monitor the impact of splitting on the overall project schedule and resource allocation. Make necessary adjustments based on progress and unforeseen events.

• Collaboration and Communication: Ensure effective communication and collaboration among project team members, especially when splitting affects multiple activities or resources.

• Standardize Procedures: Establish standardized procedures for splitting activities to maintain consistency and avoid errors.

Chapter 5: Case Studies

(This section would require specific examples. Below are outlines for potential case studies. Real data would need to be substituted for illustrative purposes.)

Case Study 1: Optimizing Drilling Rig Utilization:

• Problem: A drilling contractor has multiple drilling rigs and several wells to drill. Rig utilization was low due to long durations for individual well activities.

• Solution: Splitting drilling operations into distinct phases (drilling, casing, completion) allowed for better allocation of rigs to different wells, maximizing their utilization and reducing overall project duration.

• Results: Increased rig utilization by X%, reduced project completion time by Y days, and resulted in Z cost savings.

Case Study 2: Mitigating Delays in Offshore Platform Construction:

• Problem: Delays in the delivery of critical equipment threatened to significantly impact the schedule of an offshore platform construction project.

• Solution: Splitting activities dependent on the delayed equipment allowed the project team to continue with other tasks, minimizing the overall project delay.

• Results: Successfully mitigated the impact of equipment delays, limiting project overrun to only A days instead of the originally projected B days.

These case studies demonstrate the potential benefits of splitting in different contexts within the oil and gas industry. The key is careful planning, execution, and monitoring to maximize efficiency and minimize risks.
