Atlas is a web-application developed by Hecate for investigating trends in the data collected during BOP testing. The application is hosted in Microsoft Azure, is available from any web-browser anywhere in the world, is secure and is themed for each client.
All of the data from every BOP test that utilized GreenLight is managed in Atlas. This includes the proprietary GreenLight files themselves as well as the Leaflet reports, Blueprint test plans and any auxiliary data collected during testing. Test data is searchable and can be filtered based on operators, rigs, date ranges, etc.
In addition to standard data management tasks, Atlas automatically calculates a wide range of key performance indicators (KPIs) for every dataset collected. These KPIs include high-level statistics such as the total number of tests, the total duration of the entire test series, the total amount of time on pressure and the total amount of time when no pressure is applied. More detailed KPIs are also calculated and include the individual durations of low pressure tests, the individual durations of high pressure tests and the amount of time a low or high pressure test was held beyond the time necessary to complete the test safely and in compliance with regulations.
How can these KPIs improve operations? High-level statistics are useful for doing broad comparisons between test series – week-after-week on the same rig as well as between different rigs working in comparable environments – which can quickly illuminate areas to focus on for efficiency improvements. For example, an excessive amount of time in a single test series without pressure applied may point to an opportunity to decrease the amount of time spent lining-up valves between tests. These gross improvements can be followed by fine-tuning based on more detailed KPIs. Efficiency improvements lead to reduced testing time which increases safety a.) by minimizing the amount of time rig personnel are exposed to high pressures and b.) by reducing needless wear-and-tear on critical well control equipment.
Trends in KPIs also have the potential to change the maintenance schedule of rig components. While individual tests of the blowout preventer (BOP) may result in regulations being met week-after-week, subtle trends in the data that do not contradict these results may indicate the need to push the schedule for preventative maintenance (PM) forward. Pushing PM forward gives the rig control over when and how an issue gets addressed.
Atlas organizes all of the data collected by GreenLight which was approved for use as the system-of-record for BOP tests by the Bureau of Safety and Environmental Enforcement (BSEE) in 2015 and again in 2017.
