Oil and Gas Companies Are Trying to Build Porsches But Only Have Dirty Gasoline To Fuel Them

Imagine having the fanciest, most expensive car in the world. The only fuel that is available is contaminated by just a little bit of dirt -- it doesn’t take a lot to mess a motor vehicle up. At best the car will sputter and jerk, drive slowly, and be a major disappointment. At worst, the engine will quickly die rendering the expensive car useless. One of the basic, least expensive inputs such as a $25 tank of gasoline is crucial for making a highly engineered system work.

When it comes to doing production analytics in the oil and gas industry, companies are investing a lot of resources in teams and systems only to realize that their primary input of data from the field is contaminated in some way. Their data quality issues prevent them from getting past the analytics starting line.

Improving data quality is the only way they will ever make their high-tech analytics machine work. The trouble is, they often don’t know exactly what is data quality in oil and gas or the data quality measures that are causing their data quality problem.

Why Data Quality Is Causing So Much Heartburn Now, But Should Have All Along

When oil and gas companies set out to do analytics, they want to build supersensitive models that accurately predict and diagnose problems based on the latest real-time data. The metaphor we use to explain this is the newspaper.

Today’s news is what really matters for these analytic models and what can drive decisions. However, if any of it is missing, even a short story, or if there is a small inaccuracy or the news arrives even a few minutes or hours late, then this will make it impossible to make the best decisions. In the real world, data issues cost time and money. Data quality management in oil and gas is making sure that the news is always accurate and timely so the models can help operations teams make faster and better decisions.  

Beyond a company’s analytics ambitions, poor data quality can spin companies in circles who are using SCADA to manage their business better. It causes them to chase false alarms, ignore important alarms, fix the wrong problem, and spend hours trying to decide what is really going on, while never really knowing with much certainty because of lack of trust in their data integrity. It’s only now, however, that many companies are realizing just how important data quality and data management is to their entire operation. This sends companies back to the drawing board, without really knowing how to assess their data quality and know what needs fixing.

eLynx’s Full-Stack Production Analytics Solution Builds Data Quality In From the Beginning

“How do you ensure data quality?” is one of the most frequent questions we get from companies who are trying to build their analytics capability and stumbling out the gate. This is followed by the next most frequent question, “What do you clean your data?”

Our answer is simple: we don’t clean data, we always generate clean data. Data cleansing will always be imprecise because estimates will be needed to replace errors in data or fill in missing values. Cleaning data may work to build a static analytic model from a complete data set, but in the real world, there is not time to clean data. Also, if you are constantly cleaning data, you are constantly introducing imprecision. In order to achieve consistent data quality in business analytics, the data has to be clean as it is produced from the field. We are experts in doing this.  

eLynx was the first oil and gas technology to offer and perfect SCADA as a service. This means we built the turnkey SCADA solution where we learned to work with all lift types, equipment types, and sensors to make sure they were installed and always functioning and communicating properly. Through these years of experience with many customers, we evolved our way of ensuring the right data gets read at the right intervals. We also developed a data quality assessment tool to check the quality of this on an ongoing basis.  

This allows us to quickly spot and fix problems so today’s news in the oil and gas operation is as accurate and timely as possible. When companies want to go to the next level with analytics they will already have real-time quality data.
