PDM Finish to Finish Relationship

PDM Finish-to-Finish Relationship in Oil & Gas: Understanding the "Lag" Factor

In the intricate world of oil and gas project management, ensuring seamless coordination between various activities is crucial. Project Data Management (PDM) systems, specifically their scheduling tools, utilize relationships between tasks to achieve this synchronization. One such relationship, often overlooked, is the Finish-to-Finish (FF) relationship with a "lag."

What is a Finish-to-Finish (FF) Relationship?

A Finish-to-Finish (FF) relationship dictates that a task's completion date is dependent on the completion date of another task, with a specific "lag" time. Think of it as a "wait period" after the first task ends before the second task can begin.

How does it work in Oil & Gas?

Imagine a scenario involving drilling operations and subsequent well completion activities.

  • Task 1: Drill a well to a specific depth.
  • Task 2: Run production tubing and install downhole equipment.

Here, Task 2 (tubing and equipment installation) can't begin immediately after Task 1 (drilling) ends. A specific "lag" is needed. This lag might represent:

  • Time for pressure stabilization: The well needs to stabilize after drilling before equipment can be installed.
  • Specialized equipment mobilization: Specialized equipment for tubing and equipment installation needs to be transported to the site.
  • Safety checks: Extensive inspections and safety checks are mandatory before continuing.

Why is FF with Lag crucial in Oil & Gas?

  • Safety: Implementing lags ensures that essential safety procedures are completed before proceeding to the next phase.
  • Quality: Lag periods allow for proper pressure stabilization, avoiding potential damage to downhole equipment.
  • Optimization: FF relationships with lags help optimize resource allocation, ensuring the availability of specialized equipment and personnel when needed.

Example:

  • Task 1 (Drilling): Finishes on August 10th.
  • Task 2 (Tubing and Equipment): FF relationship with Task 1, with a 2-day lag.
  • Therefore, Task 2 can begin on August 12th.

PDM Software and FF Relationships:

PDM systems like Primavera P6 and Oracle Primavera Cloud provide tools to define and manage these FF relationships with lags. This allows project managers to:

  • Visualize dependencies: Easily identify and understand the flow of tasks and their relationships.
  • Schedule efficiently: Ensure proper sequencing and avoid delays caused by neglecting necessary lag times.
  • Track progress: Monitor the completion status of tasks and proactively manage potential risks.

Conclusion:

The Finish-to-Finish (FF) relationship with a lag is a powerful tool in PDM systems for managing complex oil and gas projects. By implementing this relationship, project teams can ensure safety, optimize schedules, and maintain project quality. Understanding and utilizing this feature effectively is crucial for project success in the demanding oil and gas industry.

Quiz: PDM Finish-to-Finish Relationship in Oil & Gas

Instructions: Choose the best answer for each question.

1. Which statement best describes a Finish-to-Finish (FF) relationship in project management?

a) A task cannot start until another task has finished. b) A task's completion date is dependent on another task's completion date, with a lag time. c) A task must finish before another task can start. d) A task's start date is dependent on another task's completion date.

Answer

b) A task's completion date is dependent on another task's completion date, with a lag time.

2. What is the primary purpose of using a lag in an FF relationship?

a) To ensure tasks are completed in a specific order. b) To create a buffer between tasks to account for potential delays. c) To allow for necessary activities to be completed between tasks. d) To shorten the overall project duration.

Answer

c) To allow for necessary activities to be completed between tasks.

3. In an oil and gas drilling project, what could be a reason for a lag in an FF relationship between drilling a well and running production tubing?

a) The drilling rig needs to be moved to a new location. b) The well needs to be stabilized before equipment installation. c) The drilling crew needs to be trained on new equipment. d) The production tubing needs to be ordered from a supplier.

Answer

b) The well needs to be stabilized before equipment installation.

4. Which of the following benefits is NOT associated with using FF relationships with lags in oil and gas projects?

a) Improved project safety. b) Optimized resource allocation. c) Reduced project costs. d) Enhanced project quality.

Answer

c) Reduced project costs. While FF relationships can help optimize resource allocation, they might not always directly lead to reduced project costs.

5. What is a key advantage of using PDM software for managing FF relationships with lags?

a) PDM software can automatically generate project schedules. b) PDM software can track project progress and identify potential risks. c) PDM software can eliminate the need for project meetings. d) PDM software can create detailed project budgets.

Answer

b) PDM software can track project progress and identify potential risks.

Exercise: PDM Finish-to-Finish with Lag

Scenario:

You are managing a well completion project with the following tasks:

  • Task 1: Drilling the well to a depth of 10,000 feet (estimated completion: August 20th).
  • Task 2: Running production casing and cementing (estimated duration: 5 days).
  • Task 3: Installing downhole equipment (estimated duration: 3 days).

Requirements:

  • There is a mandatory 2-day lag between the completion of Task 1 and the start of Task 2.
  • Task 3 cannot begin until Task 2 is complete.

Your task:

  • Using the provided information, determine the earliest possible start date for Task 3.
  • Explain your reasoning.

Exercice Correction

Here's the solution: * Task 1 completes on August 20th. * There is a 2-day lag, so Task 2 can begin on August 22nd (August 20th + 2 days). * Task 2 has a duration of 5 days, so it completes on August 27th (August 22nd + 5 days). * Task 3 cannot start until Task 2 is complete, so the earliest possible start date for Task 3 is August 28th. Therefore, the earliest possible start date for Task 3 is August 28th.
