Camera sub is one type of MWD equipment sub. Manufactured in 4145H or P500 Series material witch has high yield strenth. This sub is used for gathering infor inside the borehole. A camaera in inserted in the attachment given on box connection with metal plate and threading by which the camera in properly tighted and can be used in inspection of the borehole. A camera sub is a type of downhole tool used in the oil and gas industry to capture images and video footage of the wellbore during drilling or wellbore inspection operations. It is typically a cylindrical tool that contains a high-resolution camera and lighting system.

The camera sub is typically placed in the drill string or on a wireline and lowered into the wellbore to capture images and video footage of the wellbore. The camera sub can be remotely operated and controlled from the surface, allowing for real-time monitoring and inspection of the wellbore.

The camera sub is designed to withstand the harsh and high-pressure environment of the wellbore, and is typically made from high-strength materials, such as alloy steel or titanium. It may also be equipped with additional features, such as a measurement system to provide information about the size and shape of the wellbore.

Overall, the camera sub plays an important role in the oil and gas industry, as it enables the inspection and monitoring of the wellbore to ensure the efficient and safe operation of the well. The images and video footage captured by the camera sub can be used to identify potential issues or defects in the wellbore, allowing for timely maintenance and repairs to be made.
