Real time monitoring of drilling operations has added value and with increasing cost per foot of well bores due to their complexity it makes real time monitoring of drilling operations a key element of drilling cost reduction. With the emergence of rig sensors, WITSML, and the capturing of data with MWD systems, the industry is actively working to increase the utilization of real time data to support drilling decisions in control rooms and real-time operation centers (RTOCs). One of the main purposes of these data centers is to support drilling teams in their decision-making process.

The ability to detect drilling dysfunctions immediately helps to prevent catastrophic failures of BHA components, to reduce NPT and to increase on-bottom time. Up to now, drilling dynamics problems such as stick-slip, bouncing or whirl required downhole data for timely mitigation. However, the collection of downhole data required the usage of expensive data recorders that represented an additional cost and an additional risk of BHA problem. Thanks to the increase of the volume of data collected by mud logging companies and the development of sophisticated algorithms, Varel has developed a drilling dysfunction detection method using only surface data. It is called DrillPerf.

Say Hello to the Curves of Your Dreams


Formations with high clay content are known to cause severe bit balling due to their sticky consistency. Varel’s new curved nozzle technology is designed specifically for use in these clay-heavy formation. These nozzles direct fluid flow based on their orientation and can be rotated 360° when installing to accommodate the proper position along the face of a blade or down the junk slot. This combination of a lateral jet and fluid direction takes advantage of existing fluid energy without sacrificing TFA.

Varel curved nozzle technology is fully interchangeable with standard nozzles and requires no additional design time, allowing for rapid delivery. The nozzles are available in 55 and 65 series sizes and can be used with Varel’s Raider® and Voyager® product lines. For more information, see our Curved Nozzle bulletin or contact your local Varel representative
