Managing Drilling data at Reliance

Thursday, June 25, 2015

Reliance Industries is building a central repository for its drilling data, and developing processes to ensure the data is high quality. Rashmi Bhangale, Data manager with Reliance Industries in Mumbai, explained how it works

"Drilling is the most expensive and challenging part of the [E&P] business," said Rashmi Bhangale, Data manager with Reliance Industries, speaking at the Digital Energy Journal forum in Mumbai on February 4, "Doing More with E+P Data".

This means that drilling offers maybe the best opportunity for improving cost performance, she said.

And by having drilling data better organised and structured, it should be possible to identify ways to reduce costs and improve performance, she said.

Once you have good data, "you can derive business value out of it," she said. "You can make faster and better informed decisions. You can plan your future wells."

Reliance set an objective to have a central database, which would provide good quality drilling data to people in accordance with the requirements of their role.

"All this data will help us for statistical analysis and benchmarking," she said. "One truth, one data. You can ensure the data is trusted. It will help us to track operational efficiency, and also prepare for the future. You have the consistent data in the office."

The central database can generate drilling reports and statistics, to be sent to the government to meet regulatory requirements, and also to be used within the company.

Reliance is using Landmark's Engineer's Data Model (EDM) as a centralised data repository.

The reporting and analysis done by Halliburton Landmark's OpenWells operations reporting system.

Data capture

Data would be captured as it is generated at the rig.

The database will include data from drilling operations, completions, well testing, and quality control reports.

It gathers data about causes of non-productive time (NPT) and lessons learned.

The most important aspect of drilling reporting is the Daily Drilling Report, "which everybody looks forward to," she said.

The data is automatically replicated to the central server as soon as it is gathered. So the information is made available to authorised interpreters immediately after it is entered.


Integrating data together when it is in different data formats is difficult.

"Every contractor has their own way of storing the data," she said. "Large volumes of complex data in different proprietary formats are generated."

"If data sources and formats are different it is very difficult to correlate the data."

Reliance has a project underway to standardise the nomenclature which is being used in drilling, so everybody uses the same terminology and vocabulary.

Quality control

The data will have consistent quality control, with defined best practises, workflows and procedures, units of measure, activity and cost codes, she said.

It is then validated for correctness and completeness. The quality control would be done both by drilling engineers in rig and office and the petroleum data management team. The quality control is done manually.
