What is RSS in directional drilling?
A rotary steerable system (RSS) is a form of drilling technology used in directional drilling. It employs the use of specialized downhole equipment to replace conventional directional tools such as mud motors.
What is mud motor in drilling?
A mud motor (or drilling motor) is a progressive cavity positive displacement pump (PCPD) placed in the drill string to provide additional power to the bit while drilling. In certain applications, compressed air, or other gas, can be used for mud motor input power.
What is a steerable motor?
1. n. [Drilling] A mud motor incorporating a bent housing that may be stabilized like a rotary bottomhole assembly. A steerable motor can be used to steer the wellbore without drillstring rotation in directional drilling operations, or to drill ahead in a rotary drilling mode.
What is the function of rotary steerable system?
A tool designed to drill directionally with continuous rotation from the surface, eliminating the need to slide a steerable motor. Rotary steerable systems typically are deployed when drilling directional, horizontal, or extended-reach wells.
What is RSS in oil and gas?
RSS (really simple syndication) service is a means by which Oil & Gas IQ offers feeds of story headlines in XML format (“RSS Content”) to visitors to Oil & Gas IQ who use RSS aggregators. These Terms of Use govern your use of the RSS service.
What is non steerable system?
Pipe Ramming: A non-steerable system of forming a bore by driving an open-ended steel casing using a percussion hammer from a Launch Pit. The soil may be removed from the casing by augering, jetting, or with compressed air. Pipe Splitting: Replacement method for breaking an existing pipe by longitudinal slitting.
What is motor yield in directional drilling?
The motor yield projection is a powerful new projection type which adds more flexibility to a Drakewell directional driller’s toolbox. By entering the Course Length, Expected Motor Yield, Expected Toolface, and Expected Slide Footage, Drakewell will calculate where you will land if those parameters hold true.
How does a motor work in drilling?
The flow of the drilling mud through the motor would force the rotor to rotate. Through this connection the drill bit is turned at the same rotational speed as the rotor. The drilling mud exits the motor at the bottom end and flows through the drill bit open orifices (or nozzles).
What are directional drilling tools?
The most common deviation tools for directional drilling are steerable motor assemblies (or so-called positive-displacement motors [PDMs]) and rotary steerable systems (RSSs).
What is whipstock drilling?
Whipstock as the Directional Drilling Tool. After drilling the well to the kickoff point, the bit is pulled out of the hole. A whipstock is a wedge that is set in the hole. The fat edge of the wedge is on the bottom of the hole. The drillstring is rotated and the bit drills formation to the planned direction.
What is rotary drilling?
Rotary drilling is used to form a deep observation borehole or for obtaining representative samples of rock. The drilling method involves a powered rotary cutting head on the end of a shaft, driven into the ground as it rotates. The system requires lubrication (air, water or drilling mud) to keep the cutting head cool.
What is power drive drilling?
The PowerDrive vorteX RSS enables drilling with increased ROP, maximizes power at the bit to drill longer runs, and increases the rig’s operating envelope. Its rotation conditions the hole while drilling and is proven to reduce risk of sticking, casing wear, and drillstring fatigue.
