VISAGE Diagnostic Workflows: Optimizing Production Performance

February 2, 2015 by

Editor’s Note: While VISAGE rebranded to VERDAZO in April 2016, we haven’t changed the VISAGE name in our previous blog posts. We’re proud of our decade of work as VISAGE and that lives on within these blogs. Enjoy.

What oil and gas producer doesn’t want to be efficient, to “achieve maximum productivity with minimum wasted effort or expense”? In a market of low oil and gas prices, efficiency is on the mind of most VISAGE users. That’s why we have been equipping them with “diagnostic workflows.

Diagnostic workflows allow people to identify, prioritize, assess and investigate the greatest opportunities to optimize … in just seconds. The three main areas where our clients have deployed diagnostic workflows will be the focus of this blog series:

Production performance: reduce downtime and identify reoccurring patterns

Financial performance: optimize netback and minimize operating expenses

Performance to forecast: ensure cash flow is there to support upcoming activities and avoid potential reserve write-down.

A diagnostic workflow can be applied to any optimization effort. The structure of the workflow is quite simple and relies on a series of charts and/or reports that fulfill each of these steps:

1)      Identify, & Prioritize

  • What are the biggest opportunities?
  • Which opportunities have the greatest impact?

2)      Inform & Assess

  • What is the cause?
  • Can I do anything about this?

3)      Investigate

  • Support decisions and actions with the necessary detail.

To illustrate the concept I’ll walk you through these three steps as they pertain to a Production Performance Diagnostic Workflow.

1)      Identify and Prioritize

The chart below shows:

  • the Diagnostic Measure (on the y-axis) is Lost Production (which is described in a previous blog).
  • the Contextual Measure is Capability, that is the production rate I should expect from the well on days when it produces for 24 hours
  • the wells (each well is a point) have been Categorized by the Last Downtime Reason to help identify the greatest opportunities

We will select the well with a Broken Rod that has the highest Lost Production and launch our next chart (a simple right click in VISAGE) to learn more about that well.

2) Inform and Assess

The chart below shows that the Lost Production due to Broken Rods has occurred twice in the last month. Further investigation is required.

3) Investigate

The chart below provides supporting details to better understand the issue before making an informed decision about what actions to take. In this case we can see the workover details coming from one system integrated with production data from another system.

That concludes this week’s blog. Next blog will focus on a Financial Performance Diagnostic Workflow.
