Innovative Drilling Systems
By SDI, Worldwide Provider of Directional & Horizontal Drilling Services
Scientific Drilling International (SDI) configures TITAN drill motors to deal with the harsher drilling environments now commonly seen as part of our day-to-day directional drilling operations.
These tougher motors are available in most common standard, extended, and super extended power section formats along with motors designed for air, mist and foam applications.
TITAN motors use Robbins & Myers power sections. The most common configurations are listed in the SDI Motor Handbook (Request a copy) For specific project needs, there is the option of ordering specialized power sections, e.g. Ultra High speed (300-600 RPM) or Uniform Thickness of Rubber (UTR).
The Smart Motor is available for use in near-bit measurement applications. The motor configuration has a dual sensor array (gamma and inclination measurement) placed less than six feet above the bit. Data is wirelessly transmitted back to the MWD for processing. Tools are currently available in 3-3/4", 4-3/4" and 6-1/2" O.D.
SDI is developing a rotary steerable system and it is currently in commercial field trials of the 740 SRX system designed for 8-3/4" to 9-7/8" wellbores.
Although the 740 SRX was an initial test platform for many scientific features and concepts, the tool has performed quite well in the right applications. The 740 SRX is available for low build rate work in vertical maintain applications, slant wells or s-shaped drilling applications.
While ongoing tests of the 740 SRX tool continue, a 650 SRX tool is being designed for a 7-7/8" to 8-3/4" wellbore size. This system will have higher build rate capability, rated to 329°F(165°C) . It has three steering pads with more force to provide better steering control in a wide variety of formations. This system will have near bit inclination measurements and will be able to provide bi-directional communication to either a mud pulse or electromagnetic pulse MWD system.
The 650 SRX is also designed to run with a drill motor power section to help increase bit speed and drilling penetration rates. This system is tailored for the onshore drilling market and has modular electronic and hydraulic features for efficient servicing. The 650 SRX has an intense focus on high reliability, good serviceability and low operational cost.
The DHV Tool was developed to enhance directional drilling operations. The tool is run above the motor, but typically 600 to1000 feet behind the bit. The oscillating movement within the system results in improved ROP, smoother drilling, and lessens the chance of sidewall sticking. Tools are available in 4-3/4" and 6-1/2" O.D.
