Brunei Shell - monitoring compliance of wells data

Brunei Shell has developed a Spotfire based tool to monitor compliance of its wells data with the company standard. Nurhamizam Yussop, wells and production technology data technician with Brunei Shell, explained how it works.

Brunei Shell has developed a Spotfire based tool to monitor whether its wells data is in compliance with the company standard. Nurhamizam Yussop, wells and production technology data technician, explained how it works.

Nurhamizam Yussop has been with Brunei Shell for 11 years, initially as a mechanical engineer, assisting with production technology, then moved to the technical data management team for wells and production technology in 2015. He has been involved in a number of other Spotfire projects in subsurface, logistics and change management.

Nurhamizam Yussop did a project to see if it was possible to automate the quality control running Spotfire directly on some of the reports, such as the casing report. If you know what tables and columns you are looking for, you can write script to run in Spotfire, to tell you if that data is available.

You can quickly pinpoint errors. There is no need to open up each report separately.

Web engineers can also directly access the dashboard through Spotfire's web client.

As an example, you can see all the rigs, which wells are currently active from each rig, and the reports which have been provided so far. If everything is available, the well is shown as green on the dashboard.

It is possible to look deeper into the causes of problems, such as a problem reporting casing in the Engineering Data Management system.

There are logic rules, such as that the outer diameter of casing or tubing should be larger than the inner diameter. If the inner diameter is larger, 'it will say no'.

The 'proof of concept' of the project was completed in summer 2019, on the Spotfire development server, and will now be moved to the production server.

Basic process

The company operates a number of rigs, continuously drilling wells. Well site engineers are asked to leave copies of their wells data and documents in the company's standard wells database, EDM OpenWells software from Halliburton.

There is an 'Operating Reporting Standard' in the company, to state what data is needed for each well.

There is also a checklist of everything the wells team need to send.

After data has been deposited in the Engineering Data Model (EDM) the data flows to a 'staging area'. The data team need to check the data for anything which needs correcting.

The company's technical data specialists do checks of the data for quality and completeness. Checks include whether there is data about the casing and primary cementing, the base of cement, the leak off tests, the well properties. Altogether there are 100 fields to be checked.

If anything is missing, for example a missing attachment, comments can be entered, and it is sent to the rig team.

Well site drilling engineers normally work 2 weeks on, 2 weeks off. If requests for amendments are sent to crew A, sometimes you have to wait another two weeks until Crew A resume work on the rigs, he said.

Once data about casing, cementing, completion and other aspects is in the system, it can generate a well status diagram. This is sent to the completion engineer to check, and then sent to the well owner for final approval.

Finally, the well status diagram can be handed to the well activity owner and used during the lifecycle of the well. The wells data is also used by a number of other applications.

It is important that the data is accurate. If the company ended up with incorrect well data, it might plan maintenance wrongly, he said.
