HMH Smart Modules

EKD
EKD Smart Module by HMH is a robust and easy-to-use software module that automatically detects kick (influx) or loss during various drilling operations. The adaptive detection algorithm which requires no extra instrumentation or manual configuration inputs, adjusts automatically to the current well. It continuously analyses the well conditions and informs the driller if a kick or loss is detected. EKD Smart Module is a fully integrated add-on to HMH’s standard drilling control system and HMI.

EKD calculates at real time, estimates of any influx or loss, and warnings/alarms if predefined limits are exceeded. The EKD HMI is integrated seamlessly into HMH’s standardized HMI.
The natural dynamic variations in mud volume during various drilling operations are accounted for, thus reducing the number of false alarms. The unique self-learning algorithm requires no manual inputs of configuration data to set up the system, and it will adapt to the current well and situation.
EKD utilizes the sensors and communication interface already present on the rig, hence no new instrumentation is required.

Soft Torque-Z
Soft Torque-Z system mitigates oscillations on the drill bit and torsional vibrations, with ease. The Soft Torque-Z effortlessly incorporates Shell’s proven Z-torque technology with a user-friendly automated interface, designed to reduce well cost and optimize rig efficiency.

During drilling operations, the top drive provides continuous torque and revolutions per minute (RPM) to the drill string unit. Due to varying geological conditions and drill bit frictions, the constant input from the top drive does not give a constant output on the drillbit, resulting in large fluctuations of torque and RPM down at the bottom hole assembly (BHA). This leads to torsional vibrations, also known as stick slip effect, negatively impacting drilling performance and equipment deterioration.

optiWOB
The HMH optiWOB smart module minimizes weight on bit (WOB) variations and boosts the performance of the drill string compensating system.

In all heave compensator systems, there is friction. This comes from cylinder pistons, wire sheaves, guide rails, etc. This friction force works against the heave motion and results in variations in weight on bit (WOB) when drilling.

WOB variations lead to several disadvantages:

• Reduced rate of penetration (ROP)
• Excessive wear on drill bit
• High WOB setting or risk bit lift off
• Fluctuations in rotation torque

Our optiWOB smart module counters the friction in the passive compensator system by using the Active Heave Compensator (AHC) already installed on most HMH compensators and RamRig™ deliveries. optiWOB increases the possible drilling rate of penetration and reduces wear on the drilling equipment.
