ADT® Drilling Optimization Service

ADT Drilling Optimization ServiceSperry Drilling services'  ADT® drilling optimization service helps you optimize your drilling practices through a proven philosophy of modeling, measuring and optimizing by expert personnel.

The three areas of ADT service expertise that are targeted to provide the most value to the well construction process include drillstring integrity, hydraulics management and wellbore integrity.

Drillstring integrity focuses on:

  • prevention of mechanical overload
  • protection from fatigue
  • minimizing excessive shock and vibration.

Specialized software is used to model every bottom hole assembly (BHA) and drillstring. Downhole and surface vibration detection sensors allow the ADT service specialist to measure harmful vibration modes and identify active vibration mechanisms. Correlation with formation evaluation data and surface drilling parameters enables you to take the correct actions to reduce damaging vibration and improve performance. Root cause analysis and effective documentation of experience and lessons learned help ensure continued improvement in BHA design, bit and drive selections.

Hydraulics management focuses on:

  • maintaining annular pressures within wellbore pressure boundaries
  • optimizing hole cleaning and clean-up cycles
  • optimizing circulating system pressures
  • maximizing ROP without exceeding mud weight windows
  • optimizing tripping time

The ADT service specialist models static and real-time hydraulics and torque and drag to predict the expected drilling conditions. Advanced DrillAhead® hydraulics software is used to model the location and severity of cuttings bed build up and hole cleaning efficiency. Hydraulics models can predict the effect of temperature, pressure and compressibility on downhole mud properties and resulting hole cleaning efficiency and system pressures.

Wellbore integrity focuses on:

  • defining upper and lower wellbore pressure limits
  • identifying the optimum mud weight window.

The ADT service specialist can predict the pore pressure caused by various mechanisms, fracture pressure, and hole collapse pressures. The industry-leading Drillworks® software is used to provide comprehensive pre-well analysis and wellsite surveillance services to determine the mechanisms of pore pressure generation within a prospect. Advanced pore pressure, geomechanical and basin models can also be developed and updated in real time. Using real-time formation evaluation data, including sonic, density, resistivity and gamma ray, enables the ADT service specialist to update and refine the expected conditions. Recommendations are then made to help ensure wellbore integrity and stability, maximize ROP, extend target depth criteria and optimize or eliminate casing points. It removes uncertainty in mud weight decisions, and integrates with the Hydraulics Management service to maximize performance while helping to maintain safe drilling conditions.

Summary Summary Brunei: ADT® Optimization Service Helps Ensure Critical Hole Cleaning, Cuts NPT in Long ERD Well Sign in required
In order to deliver their production requirements for the year, an operator needed to successfully drill and case a 20,000-foot (6,096-meter) extended reach well located offshore Brunei in 108 feet (33 meters) of water. Because hole cleaning is always a challenge in Extended Reach Drilling (ERD) wells, the operator sought risk management support related to hole cleaning and friction factor monitoring that would ensure the well reached planned target depth (TD).

Summary Summary UAE: First Geo-Pilot® Dirigo Rotary Steerable Run in UAE Lands Complex Sign in required
An operator planned the first fork-type multilateral well design in the United Arab Emirates (UAE) to be drilled from an offshore platform. The complexity of the program would require advanced geosteering capabilities to achieve maximum reservoir contact and precise placement of the forked-shape laterals with full accessibility for well intervention. The target was just 600 feet (183 meters) south of the platform and required a “pregnant lady” well profile through a very challenging shale formation where historically no directional work is recommended. With only one available platform slot, located on the northwest side, the well would first have to be nudged and turned in the 16-inch hole in order to reduce surface collision risk, and would then encounter a channel at the 13-3/8-inch casing point known to cause huge losses. In the 12 ¼-inch hole, a required open-hole sidetrack would present yet another challenge. And furthermore, the 8-½-inch lateral interval would have to be maintained within the reservoir target of just two feet (0.61 meters) in thickness.
