Irrigation without any reliable water resources is a challenge and even impossible. Water boreholes are required to provide sufficient water for irrigation throughout dry months in summer when the precipitation rate is usually less than in other months. To keep a high rate and efficient production in agriculture, maintenance of water boreholes is a must. Video inspection is one of the best ways to inspect and find potential borehole-related issues. The following sections will explain more about this technique in terms of its importance, operation, and the necessity of doing this before the deposition on screen and casing of boreholes.
One of our key services is video inspection, also known as videometry. Reliable water resources are crucial for irrigation, especially during dry months when precipitation rates are low. To maintain a high rate and efficient production in agriculture, borehole maintenance is necessary. Video inspection is one of the best ways to inspect and identify potential issues. It involves using a camera to record a video of the borehole’s condition and any phenomena present. This allows us to identify borehole failures and determine the best remediation method to restore the borehole to its original state. By inspecting a borehole using this technique, we can determine the degree of screen perforation clogging, which is essential for identifying the most effective rehabilitation method. Our team of experts provides video inspections for deep boreholes up to 500 meters deep.
Farmers and stockholders commonly face issues with water boreholes, such as sand production, turbidity of water, reduction of water yield, and fracture and deformation of boreholes’ casing. Boreholes, like any mechanical systems, face aging problems throughout their lifespans. Therefore, it is important to conduct video inspections to identify potential issues. This involves observing the physical condition of boreholes (casing and screen) and the aquifer’s circumstances (karstic and alluvial aquifers) in the wellbore without casing and casing, similar to endoscopy in medical science. The video inspection records the observation with depth and lateral perspective in the desired depth. All the video is recorded during the inspection.
Video inspection is a cost-effective and useful method to identify borehole-related. This helps to quickly and easily find the problem and prevent further issues. Video inspection is similar to a doctor finding a cure for a medical issue.
Acquiring data through video inspection involves:
- Characterizing water table.
- Determine the depth of the borehole and inspect the casing and screen.
- Detect any external objects that may have fallen into the borehole, and determine their location and direction.
- Identify the rate and type of sedimentation on the screen and casing.
- Determine the reasons for any reduction in water yield.
- Characterize the attitude and location of the screen and casing.
