DrillDOC® Drilling Downhole Optimization Collar Tool

Real-time measurements of weight, torque and bending moment to characterize the transfer of energy from surface to bit.

Sperry Drilling services' DrillDOC® tool provides real-time measurements of weight, torque and bending on bit to characterize the transfer of energy from surface to the bit. These measurements help optimize drilling parameters to maximize performance and minimize wasted energy transfer and vibration. The DrillDOC tool contains multiple sensors to provide the weight, torque and bending moment values and has a vibration sensor that delivers a full suite of vibration measurements. This integration ensures that the full movement of the BHA is measured through all aspects of the drilling process.

Summary Summary Halliburton Expands Line of DrillDOC® Drilling Optimization Tools
HOUSTON – Jan. 17, 2014 – Sperry Drilling, a Halliburton (NYSE: HAL) business line, has introduced two new sizes of DrillDOC® drilling optimization tools -- 4 3/4-inch and 9 1/2-inch collars. The addition of the two new sizes is especially beneficial while drilling complex directional well trajectories and horizontal or extended reach wells.
Summary Summary Gulf of Mexico: New Approach Enables Operator to Determine Successful Completion Operation Sign in required
In a deepwater (water depth over 4,000 ft (1,219 m)) Gulf of Mexico subsalt wellbore, an operator sought to run its completion string in a very challenging environment. The upper borehole section had undesired tortuosity and high dogleg severity that had caused operational difficulties in the past.
Summary Summary GOM: DrillDOC™ and Geo-Pilot® RSS Services Drill Multiple Salt Sections to TD in Single Runs Sign in required
While drilling a vertical well in 4,500 ft (1,372 m) of water, a Gulf of Mexico operator reached a challenging 17,000-ft (5,182-m) salt section (which was notorious for wellbore instability and inclinational deviation) at 5,255 ft (1,602 m) measured depth (MD).
Summary Summary Brazil: Operator Saves US$75 Million in Ultra-Deepwater Well with High Vibration and Salt Creep Issues Sign in required
An operator had a plan to drill a 5,734-ft (1,748-m) ultra-deepwater well in 149 days that was characterized as having high vibration issues in a salt formation and a long history of competitor failures.
Summary Summary Oklahoma, USA: Geo-Pilot® GXT System and DrillDOC® Tool Help Improve Drilling Performance in Shale Reservoir Sign in required
An operator in Oklahoma recently saved three days of drilling time by using a drilling solution provided by Sperry Drilling comprised of a Geo-Pilot® GXT rotary steerable system and a DrillDOC® drilling optimization tool.
Summary Summary North Sea, Norway: Operator Successfully Runs 5 ¾-inch Slim-Hole Drilling Operation with Geo-Pilot® RSS System Sign in required
In a mature field on the Norwegian Continental Shelf of the North Sea, an operator had attempted twice to drill a new extended-reach drilling (ERD) wellbore with a 2.05 measured depth (MD) to true vertical depth (TVD) ratio that resulted in the bottomhole assembly (BHA) becoming lost in hole above the reservoir.
Summary Summary USA, North Dakota: Planning, Collaboration and an Optimized Drilling Performance Deliver Record-Breaking Extended Reach Unconventionals Wells in Bakken/Three Forks Sign in required
An operator's objective was to drill two extended reach wells, followed by drilling three more wells with 50 percent longer laterals
Summary Summary DrillDOC® Drilling Downhole Optimization Collar Tool
Provides real-time measurements of weight, torque and bending moment to characterize the transfer of energy from surface to bit.
