- Real-time drilling optimization (based on both surface and downhole recorded data)
Downhole Mud Loss Indicator
An authentic real-time approach for monitoring and control of downhole fluid hydraulics should incorporate both model
physics and downhole measurements. Physical models are
formulated as differential equations of mass and momentum conservation, which are discretized along the borehole utilizing the finite element method. Using this approach in conjunction with high-frequency ASM data, flow rate and pressure along the borehole domain can be predicted in real time.
Flowrate and Pressure change between Bit-ASM1, ASM1-ASM2, and also between ASM2-ASM3
Recorded Mud loss detection
Lithology Change Indicator
The other approach of this software is to detect lithology changes by using specific energy in real-time. Based on this methodology, the wear condition of all cutters can be predicted and estimated accurately. The relationship between drilling strength and specific energy can also be used to identify differences in rock drill ability.

Automated Dull Grading
Most well records or some of the post-assessment techniques can be used to select bits based on nearby well records or other criteria. An innovative data-analytic approach is being developed to monitor the PDC bit conditions in real time. This approach incorporates and analyzes bit design parameters as well as drilling data collected along the wired pipe using a string measurement system. With this technique, it is possible to estimate and monitor bit status in real-time or in other words real-time automated dull grading.

Automated CML System
The Software presents a fully automated Controlled Mud Level (CML) system maintaining constant BHP that integrates hydraulic modeling, real-time BHP correction using downhole data (e.g., Pressure-While-Drilling-PWD and Along-String Measurement-ASM), and machine-learning-based pattern detection for early kick and loss identification.
Automated Fingerprinting (CML)
The automated CML Fingerprinting system eliminates the need to periodically recalculate mud-level connection tables during drilling operations, instead computing the required mud level to maintain a stable ECD. We introduce a machine-learning pattern-recognition method that automatically performs connection fingerprinting.
