Geothermal Wells: What Are They And How Are They Made?
Geothermal wells are intensely hot and can exceed 500 degrees Fahrenheit. This is because geothermal wells produce fluid which is heated by the earth itself. The fluids that are gathered from wells that are at a hotter temperature are often used for electrical power generation whereas the cooler geothermal fluids are used for hot tubs and spas, food processing, snow melting, space heating, and aquaculture. This why a geothermal camera for wells therefore have to be designed for high pressure and high temperature.
Geothermal wells are drills utilizing the location of water-dominated, high-temperature reservoirs, which are then drilled into using rotary drilling rigs and other conventional drilling equipment. A geothermal camera for wells and a high temperature camera is used throughout the process to gather information regarding the drilling process of the well and to avoid any mishaps. For the best geothermal camera for wells, contact a geothermal camera manufacturer to ensure the best quality geothermal imaging for you and your company.
These rotary drills are circulated throughout the well as a means of bringing the remnants to the surface. By bringing the remnants of the cutting of the well to the surface, it allows the well to cool. However, the process of drilling a geothermal well differs when the drilling is done in a steam-dominated reservoir and therefore your business must adapt itself and its drilling equipment accordingly.
The geothermal wells that are dug in a steam-dominated reservoir are drilled with the use of drilling mud. The well must be drilled above the steam entry that is first anticipated. After the well has been drilled with the drilling mud, high-pressure is used along with mud in order to reduce the amount of steam produced. This is done by plugging the pore spaces as well as the fractures in the formation of the well with the drilling mud.
After the geothermal well has been drilled and a geothermal camera for wells has been used to determine the quality of the well, steel pipe is then cemented into the drill. It’s important to cement the steel pipe thoroughly in order to prevent it from expanding under the heat of the geothermal fluid or from corroding.
Geothermal wells are an essential part to creating sustainable energy. For more information regarding geothermal wells and the equipment necessary to construct them, contact Hitwell.

These Are the Most Important Aspects of Well Inspection
Whether it’s a water well, an oil well, or any other type of groundwater system, inspections are of the utmost importance. Not only do they help gather information about the wells with downhole video camera services, they help determine whether or not there are any issues that need to be remedied immediately.
Given how important these inspections are, it makes sense that standards have been developed over time. Here are some of the basic elements that occur in a standard water or gas well inspection.
Any organization hired to provide downhole video camera services must meet a certain set of requirements. If they are performing a well inspection, they must operate under these parameters:
- Knowledge of local, regional, state, and federal laws concerning water well inspection, pump installation, and a number of other practices
- Awareness of all safety protocols in any situation related to the job or working conditions
- A base understanding of both natural and synthetic threats to any water supply
- Technical knowledge of and experience with any pumps or connected electrical components
And these are only a few of the things that must happen before an inspection even begins. There’s much more involved when the inspection actually starts.
When a qualified inspector is hired to operate a high pressure camera and perform a well inspection, they must complete the following tasks based on their assessment of the situation:
- Determine the parameters of a well’s usage such as whether it’s being used for human consumption or an industrial purpose
- Visually inspect wellhead
- Physically and visually inspect the well system itself, as well as its working components. These include storage tanks, water heaters, and filtration equipment, to name a few.
- Record specific information regarding the systems inspected, as well as suggestions for maintenance and a drafted schedule for future inspections
As you can see, downhole well inspections are a bit more rigorous than you might expect at first. And if a natural gas well is being inspected, it can travel thousands of feet below the Earth’s surface. But its inspection is still just as important as any other well’s.
Whether you’re having a well inspected or you’re trying to learn more, make sure your inspections are following these guidelines.
