HOLE STABILITY MONITORING

Anticipates and reduces unscheduled events.
• No more unwanted surprises.
• Analyze actual and theoretical cuttings volume.
• Monitor over and under pull.
• Create synthetic caliper logs in real time.

Surface measurements are the eyes and ears of your well. ILI has developed a modern Hold Stability Service, which is extremely valuable in anticipating non-productive drilling events and reducing surprises.  ILI quickly identifies hole stability issues through advanced detection of trip over and under pull conditions along with fill-on-bottom analysis.

Quantitative Cuttings Volume – QCV
ILI's quantitative cuttings tool monitors all cuttings returned from the borehole. Equipment mounted below the shale shaker will monitor continuous cuttings volumes to improve well cleaning and optimize your drilling operations by providing the following:

•  Quantitative cuttings measurement
•  Improved circulation schedules
•  Evaluating actual borehole diameter
•  Maximizing ROP
•  Effectively monitoring of wellbore stability

QCV Cutting Tray
The tray has a usable volume of 0.1 barrel or 16 liters. This volume is detected by the ultrasonic level sensor. The sensor is able to cope with residue build up. If build up becomes a problem,water spray jets are incorporated to help cleaning when emptying.

The tray is moved through 90 degrees by a 100mm stroke, 63 pneumatic actuator. The speed of operation is determined by regulators and default reload will take approximately 0.4 seconds.

To assist with monitoring and limit caking, a vibrator is activated to level cuttings in the tray. The whole tray and bearing assemblies are mounted on rubber bushes that have 4mm maximum deflection. The main tray shafts are easily removed from inside the tray without dismantling the whole device.
