Cyrus the Great expanded the Persian Empire by conquering territories with a policy of tolerance, allowing different cultures to keep their customs, which reduced rebellions. Darius I took it further by organizing the empire into provinces (satrapies), each with a governor for better control. He also introduced a unified currency, built the Royal Road to boost trade and communication, and developed an efficient tax system. These efforts helped create a stable, well-governed empire that lasted for centuries and became one of the most powerful in history.

How do oil rigs drill around a corner?
Oil rigs can drill around a corner using a technique called directional drilling. This involves gradually changing the angle of the drill bit from vertical to horizontal or at various angles, allowing it to navigate around obstacles or reach reservoirs that are not directly beneath the rig. Advanced technologies, including downhole motors and rotary steerable systems, enable precise control of the drill's trajectory. This method maximizes resource extraction while minimizing surface disruption.
When was Dando Drilling created?
Dando Drilling was created in 1867.
What do you call drilling 4876holes?
Drilling 4,876 holes can be referred to as a "bulk drilling" operation or simply "high-volume drilling." This term emphasizes the large quantity of holes being created, often for industrial, construction, or mining purposes. The specific context may further define the process, such as "mass drilling" or "production drilling."
What does a drilling contractor do?
ResponsibilitiesI am a drilling contractor and am working on this field for many years .I am owning a Sydney based drilling and boring company named AV Drilling . So i can explain you from my own experience. It is the responsibility of the Drilling Contractor to drill the well to the correct program specifications and to provide a well bore that is 'fit for purpose', subject to the terms of the contract. The Drilling Contractor shall not compromise safety or well integrity in order to reach the drilling objectives. A drilling Contractor develops, plans, costs and supervises the operations necessary for drilling oil and gas wells. They are involved from the initial well design to testing, completion and abandonment.Drilling Contractor work with other professionals, such as geologists and scientists.
What is the choke panel used for in drilling?
The choke panel in drilling is used to regulate the flow of drilling fluid (mud) during the drilling process. It allows operators to control pressure and manage wellbore stability by adjusting the flow rate of the mud being circulated. This is crucial for preventing blowouts and maintaining safe drilling conditions. Additionally, the choke panel helps in managing the return flow of cuttings and maintaining optimal drilling efficiency.
What is the difference between drilling and directional drilling?
Conventional Drilling is the drilling of a vertical well through reservoir rocks to TD. Directional drilling is the drilling of a non-vertical well horizontaly through a source rock.
What is horizontal displacement as per directional drilling?
Horizontal displacement in directional drilling refers to the distance between the starting and ending points of a horizontal wellbore. It measures how far the wellbore has deviated from its vertical axis to reach a target location. Increasing horizontal displacement allows for accessing more reservoir area from a single drilling location.
Who are the top directional drilling contractors in north America?

What has the author S J Kravits written?
S. J. Kravits has written: 'Accurate directional borehole drilling' -- subject(s): Directional drilling 'Comparison of rotary and in-hole motor techniques for drilling horizontal boreholes in coal' -- subject(s): Boring, Coalbed methane drainage, Mine ventilation
Why do you use directional drilling?
Directional drilling is used to access oil and gas reserves that are not directly beneath the drilling site, allowing for more efficient resource extraction. It minimizes surface disruption by enabling multiple wells to be drilled from a single location, reducing environmental impact. Additionally, this technique can enhance reservoir management and optimize production by targeting specific formations and avoiding obstacles. Overall, directional drilling improves operational efficiency and cost-effectiveness in resource extraction.
What is the Methods of drilling well?
Methods of drilling wells include rotary drilling, cable tool drilling, and directional drilling. Rotary drilling employs a rotating drill bit to break through rock and soil, while cable tool drilling uses a heavy bit attached to a cable that repeatedly drops to chip away at the material. Directional drilling allows for drilling at various angles, often used in oil and gas extraction to reach multiple targets from a single location. Each method has its own applications, advantages, and challenges depending on the geological conditions and project requirements.
What is SIC 1381?
includes establishments primarily engaged in drilling wells for oil and gas field operations for others on a contract or fee basis. This industry includes contractors that specialize in spudding in, drilling in, redrilling, and directional drilling.
What is the vertical cross section of a cone?
The vertical cross section of a right vertical cone is a triangle if that cross section is taken from the vertex. Any other vertical cross section will reveal a hyperbola (with endpoints on the base of the cone). A link can be found below.
What is attached to the vertical fin in a plane?
The vertical fin on a plane is primarily attached to the tail section and serves as a crucial component of the aircraft's stability and control. It houses the rudder, which is used to control yaw and maintain directional stability during flight. Additionally, the vertical fin helps to counteract aerodynamic forces and improve the overall handling characteristics of the aircraft.
What is a building section?
Section is the vertical cut of the building.....
What are the different types of drilling rigs?
There are several types of drilling rigs, primarily categorized as rotary, percussion, and directional rigs. Rotary rigs, commonly used in oil and gas exploration, use a rotating drill bit to penetrate the earth. Percussion rigs, which use a hammering action to break rock, are typically employed for shallow drilling and mineral exploration. Directional rigs are specialized for drilling at various angles, allowing for access to resources that are not directly beneath the rig's location.
