Rkb drilling rig
In the , depth in a well is the distance along a between a point of interest and a reference point or surface. It is the most common method of reference for locations in the well, and therefore, in oil industry speech, "depth" also refers to the location itself. Strictly, is a vertical coordinate related to , albeit in the opposite direction. However, "depth" in a well is not necessarily measured vertically or along a straight line.

How do you calculate depth of a drilling rig?
This depth is always calculated from the deviation survey. In most drilling operations, RKB (Rotary Kelly Bushing) is used as a reference point to measured depth. For floating drilling rigs, a mean rotary table elevation has to be used. In offshore, MSL (Mean Sea Level) is sometimes used.
What is the difference between RKB and MSL?
In most drilling operations, RKB (Rotary Kelly Bushing) is used as a reference point to measured depth. For floating drilling rigs, a mean rotary table elevation has to be used. In offshore, MSL (Mean Sea Level) is sometimes used. Variations in actual sea level from MSL can be read from tide tables or can be measured.
What is a rotary kelly bushing?
Depth measurements are commonly referenced to the RKB, such as 10,000 ft. RKB, meaning 10,000 feet below the rotary kelly bushing. RKB means rotary kelly bushing - an adapter that serves to connect the rotary table to the Kelly, which turns the entire drillstring.
How do you measure a wellbore depth from a kelly bushing?
Many wellbore depth measurements are taken from the Kelly Bushing. The Kelly bushing elevation is calculated by adding the ground level to the Kelly bushing height. Kelly bushing is that elevated device positioned right on top of the rotary table and used to transmit torque from the rotary table to the kelly.
What is a drill bushing?
Bushing that rotationally connects the rotary table to the drill string kelly bar, the top of which is commonly used as vertical reference for the drill floor. Coal: Did You Know?

What does GL mean on a rig?
Drilling reference Point on top drive rig) GL = Ground Level Elevation = Distance of GL measured from MSL (GL above MSL = +; GL below MSL = (=Water Depth) Scribd is the world's largest social reading and publishing site.
Swiss Engineering Water Drilling Rig
Transocean was formed as a result of the merger of Southern Natural Gas Company, later , with many smaller drilling companies. In 1953, the -based Southern Natural Gas Company created The Offshore Company after acquiring the joint drilling operation DeLong-McDermott from DeLong Engineering and . In 1954, the company launched Rig 51, the first mobile , in the. [pdf]FAQS about Swiss Engineering Water Drilling Rig
How does a drill work in Switzerland?
The drill is easy to install and uninstall and operates completely autonomously. Best of all, it operates on normal household current (which in Switzerland is 240 volts). While it drills, it tracks its every movement and steers itself downwards in a straight trajectory. Here’s a graphic that shows how it works.
What are oil and gas drilling rigs?
Oil and gas drilling rigs are very complex systems that contain thousands of processes which must operate 24 hours a day in remote environments and harsh weather conditions. New drilling rig construction can require more than a billion dollars of investment.
What makes our drilling rigs a high-quality and versatile product?

What was the first rig to drill in the Barents Sea?
1986 – The Transocean Arctic in Norway became the first rig to drill year-round in the Barents Sea. Santa Fe purchased the first Monarch-Class heavy-duty, harsh-environment jackup, the Monarch. Sonat Offshore Drilling, Inc. acquired the offshore drilling fleet of Dixilyn-Field (a PanHandle Eastern Company.)
Who is the second largest offshore drilling contractor in the world?
2001 - Global Marine and Santa Fe International merged to become GlobalSantaFe Corporation, the second largest drilling contractor. 2007 - Transocean and GlobalSantaFe merged as the world's largest offshore drilling contractor. Deepwater Nautilus – 8,951 feet, water depth, record for a moored rig.
Can a mini drilling rig be used in a temperate zone?
But drilling down far enough to access that temperate zone can be costly and often requires large drilling rigs powered by diesel engines. Borobotics is a Swiss company that has invented an autonomous mini drilling machine that is just 13.5 cm wide and 2.8 meters long (5½ inches by 9¼ feet).
