This is a good question!
I would like to broaden the question a bit as to who makes the decision on a drilling rig. Of particular interest is the offshore drilling rig, where there are responsibilities for quick decisions on the rig floor, and others made from land offices.
Routine decisions can be made on the rig. Other decisions are made from land office. These land offices may be in the particular company where the drilling is occuring, but others may require the home office approval. Drilling engineers, production engineers, reservoir engineers, geophysicists, and geologists may all be involved.
Often, the drilling rig is leased from a service company. They may contract the rig on a turnkey or day rate basis. A day rate basis is very common, as the service company is not taking a risk if the drilling takes longer than expected. The rig has a crew which is the service company supervisors job to supervise.
The well is drilled per the contracting oil company's (lease holder) plan. At all times, there is a company representative or "company man", present to make decisions as the drilling progresses. The company man may modify the plan however modifications to plan often require land office approvals.
Some decisions are critical, such as whether to test a prospective zone. Drilling rigs run 24 hours a day/ 7 days a week, so there is a hectic period between the first encounter of a potential producing zone and the testing plan. Ultimately, the testing plan must have the agreement of the operator and all partners (lease holder group).
What else can I help you with?
Is their always a flame burning on oil drilling rigs?
No, the presence of a continuous flame on oil drilling rigs depends on the specific equipment and processes being used. Some rigs may use a flare system to burn off excess gas or emissions, while others may not have a visible flame at all times.
How many land drilling rigs are there in the world?
There are more than 1,800 active onshore drilling rigs in operation globally today, with the most density in areas such as North America, the Middle East, and Asia. The actual figure depends on various factors, including global oil demand, investment, and exploration. At Haleys Group, we remain up-to-date with industry trends to ensure trusted drilling equipment rental services for land and offshore operations. Our customers enjoy top-of-the-range machinery, technical assistance, and customizable rental terms that cater to the needs of contemporary drilling activities.
Is petroleum removed from the Earth with steamshovels?
No, petroleum is usually extracted from the Earth using drilling methods such as drilling rigs and pumps to access underground reservoirs. Steam shovels are typically used for mining operations to extract minerals and ores from the ground.
What resource do offshore oil rigs extract from the Earth?
Offshore oil rigs extract crude oil and natural gas from beneath the ocean floor. These valuable natural resources are found in deep underground reservoirs beneath the seabed. Offshore drilling platforms are specially designed to access these reserves through advanced engineering and drilling technologies. At Haleys Group, we support offshore exploration by providing reliable rental services for oil drilling equipment, ensuring safe and efficient operations in demanding marine environments. Our certified equipment and experienced team help clients meet their offshore extraction goals with confidence.
What tools is used to dig oil wells?
Oil wells are made using a drill. A diamond/carbide embedded drill bit is attached to the end of lengths of hollow pipe which are rotated on the drilling platform and tower called a 'derrick'. Drilling mud is pumped down the drill pipe and out of nozzles in the drill bit to steer the drill and to flush debris out of the drilled hole. The weight and properties of the drilling mud are very important if you are to prevent blowouts such as that which happened in the Gulf recently.
How many types of drilling rigs are there?
There are several types of drilling rigs used for various drilling operations, each designed to suit specific purposes and geological conditions. Some of the most common types of drilling rigs include: Land Drilling Rigs: These are conventional drilling rigs used on land for oil and gas exploration, water wells, geothermal wells, and other drilling applications. Offshore Drilling Rigs: Offshore rigs are used to drill for oil and gas reserves beneath the seabed. They can be fixed platform rigs, jack-up rigs, semisubmersible rigs, or drillships. Rotary Drilling Rigs: Rotary rigs use a rotating drill bit to drill into the ground. They are versatile and widely used for various drilling applications. Cable Tool Drilling Rigs: Also known as percussion rigs, these rigs use a heavy drill bit that repeatedly drops and strikes the ground to break rocks. Directional Drilling Rigs: These rigs are designed to drill at non-vertical angles, allowing wells to access reserves located horizontally or in specific directions. Auger Drilling Rigs: Auger rigs use a helical screw-like drill bit to excavate materials, commonly used for environmental and geotechnical drilling. Reverse Circulation (RC) Drilling Rigs: RC rigs use dual-wall drill rods and a down-the-hole hammer for faster and more efficient drilling. Core Drilling Rigs: Core rigs are used to retrieve core samples from the ground, crucial for geological analysis and exploration. Sonic Drilling Rigs: Sonic rigs use high-frequency vibrations to drill and retrieve core samples with minimal disturbance to the surrounding soil. Hydraulic Drilling Rigs: These rigs use hydraulic power for drilling operations, commonly used for water wells and geotechnical investigations. Each type of drilling rig has its advantages and applications, depending on the geological conditions, drilling objectives, and project requirements. The choice of drilling rig depends on factors such as depth, drilling method, ground conditions, and the type of material being drilled. Pole Hole Drilling Rigs Manufacturers
Can anyone find a drill-your-own well drilling rig?
DIY drilling rigs are for sale everywhere, but beware of cheap toy rigs. Do your homework! .
How could drilling rigs cause pollution in the water?
If there is harmful chemicals such as petroleum or natural gases in the water and drilling rigs drill through it, the chemicals/pollution will be released into the water.
What is the history of diamond drill rigs?

What company makes the jacking system for jack up drilling rigs for NOV?
BLM
What is HAS and geoprobe drilling?
Geoprobe drilling is simply drilling with a machine called a geoprobe. They are usually smaller than most drilling rigs, and run on tracks. They are primarily used to take soil samples, and install monitoring wells.
Do semi submersible drilling rigs travel under their own power?
No. Generally they are pulled by tugboats.
What has the author Betsy Tyson written?

To drill oil do you have to cut down trees?
Some oil drilling is done on rigs at sea, where there are no trees. Some oil drilling is done in countries that are primarily deserts.
What is a drilling rig?
All drilling rigs are designed to extract a significant amount of petroleum, which is trapped underground in a porous or permeable rock formation. The most common form of drilling rig has been the rotary rig.
Where can you find an oil rigs correspondence school?
I do not think there is an actual correspondence school for Oil Rigs. Or at least I have never heard of one. There are, however, some online resources and correspondence courses for certain aspects of the drilling operation such as Blow Out Prevention, diesel mechanics, and electrical training since most of the new rigs are essentially electrical with power generated with diesel motors. There are, however, several companies that are now trying to provide training for working on drilling rigs. Nabor's Drilling is one example, with at least one school in Casper Wyoming.
How many offshore oil rigs are there?
By offshore oil rigs, I assume you mean "drilling rigs." A production platform is not a drilling rig, but it might have a drill rig (called a platform rig) in place on it from time to time to service the wells that have already been drilled. There are 454 "jack-ups", whose long truss like legs are lowered until they reach the seabed, and the deck is lefted highter to provide a stable base from which to drill In addition, there are 234 floating drilling rigs that operate in water too deep for conventional. Answer: 688 total.
