What is downlinking in drilling?
What is downlinking in drilling?
Downlinking is sending command(s) from surface to MWD tool so that two-way communication between MWD tool and MWD Engineer is established. Downlinking is needed as MWD tools must become flexible in executing tasks. Command sent to MWD tool is used to change telemetry or execute measurement on demand.
What is autonomous directional drilling?
Autonomous directional drilling is the downhole control technology guiding our tools in autonomous well construction, overcoming control-loop time and associated data-to-surface delays when downhole tools detect or encounter programed conditions, and then wait for downlinking corrective instructions.
What is an MWD tool?
MWD tools are generally capable of taking directional surveys in real time. The tool uses accelerometers and magnetometers to measure the inclination and azimuth of the wellbore at that location, and they then transmit that information to the surface.
What is autonomous drilling?
Autonomous drilling allows operators to be removed from the hazards caused by a working drill, and instead allows them to oversee the machine from a safe distance. Other advantages to autonomous drilling include increased accuracy and efficiency, leading to more productive operations.
How does a rotary steerable assembly work?
RSS are located at the very bottom of the drilling assembly, sometimes in excess of 5km long and rotating at up to 250rpm, and work by constantly pointing the drill bit in the desired hole direction.
Where do drillers usually place MWD tools?
bottom hole assembly
Originally designed in the 1980s to overcome well logging challenges of wells being drilled at extreme angles, MWD is a type of Logging-While-Drilling (LWD) where tools are encompassed in a single module in the steering tool of the drillstring, at the end of the drilling apparatus (or the bottom hole assembly).
How much do MWD hands make?
How much does a MWD Field Hand in United States make? The highest salary for a MWD Field Hand in United States is $47,661 per year. The lowest salary for a MWD Field Hand in United States is $23,481 per year.
How much money does a directional driller make?

What are the benefits of autonomous drilling?
What is RSS in 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 the practice of downlinking in drilling?
Downlinking it the practice of sending commands to downhole tools (LWD or RSS for example) by any one of a number of possible methods either while continuing to drill or while off bottom standing by. The main methods are. Pressure fluctuation caused by a dedicated piece of equipment at surface.
Who are the largest offshore drilling companies in the UK?
KCA Deutag is among the largest offshore drilling companies in the UK. It is a world’s leading provider of drilling and engineering expertise and operates both onshore and offshore. A reliable brand name, KCA Deutag has won several new contracts in recent times.
What do you mean by downlinking in MWD?
Downlinking is a term used when a command is transmitted from the surface LWD computer to the tool downhole (RSS, Formation Tester, PWD etc) by the MWD Engineer.
When do you use a downhole in MWD?
Most downlinking commands are used to change telemetry format/speed (in the case of MWD and LWD) or steering instructions (in the case of RSS). Downlinking is a term used when a command is transmitted from the surface LWD computer to the tool downhole (RSS, Formation Tester, PWD etc) by the MWD Engineer.
