Rig Performance Monitoring in RIMDrill

There are certain operations during the life of a well that can be measured to produce a series of baseline characteristics of the efficiency of rig operations. These measurements can then be reviewed and compared with other wells and data from other rigs to make an assessment at how efficiently each rig is performing these operations.

The latest version of RIMDrill has a new feature to capture measurements relating to the performance of the following operations and to provide a mechanism for analyzing the results.

Tripping speeds (Restricted and Unrestricted)
Running Casing
BHA Handling
BOP Operations
BOP Testing
Cut and Slip Drill Line
Lay Down/Pick Up Drill Pipe
Washpipe Changes

These recurring and repetitive operations are common to all rigs and by some estimates can represent up to 30% of well construction time. A recent technical paper on the subject indicated variations of 25% in the time taken by similar rigs to perform similar tasks. This has resulted in a requirement for many contractors to better understand and act upon these variances.

To meet this requirement the new Rig Performance Monitoring additions to RIMDrill include the following features and benefits:

Features:

Integrated into RIMDrill daily reporting application
Simple data entry places minimal additional burden on rig crew
Flexible use of operations codes which can be assigned
Performance graphs for individual rigs
Performance graphs to allow comparisons between several rigs in the fleet

Benefits:

Provides data to develop metrics for benchmarking of key rig operational activities
Provides support for continuous improvement programs and critical process analysis
Helps identify rigs with best practices
Provides awareness and basis for intervention with poorly performing rigs
Improved crew proficiency through increased awareness of time spent on key operations
Supports requirements from some operators for rig performance data
