Discover how AIMOLI evaluated its AML921 downhole camera<\/a> for deep-well imaging, oil layer interference, and 360\u00b0 well wall observation through internal testing.<\/p>\n\n\n\n

Downhole Camera Case Study: How AIMOLI AML921 Addresses Deep-Well Imaging Challenges<\/h1>\n\n\n\n

A downhole camera needs to do more than reach the required depth. In wells containing oil and water layers, keeping the imaging lenses clear can be just as important as pressure resistance.<\/p>\n\n\n\n

This was the challenge faced by a coal mine exploration customer who contacted AIMOLI about its AML921 Digital Groundwater Downhole Camera<\/a>. The customer needed to inspect the well walls and well bottom at a depth of approximately 200\u2013300 meters. However, an oil layer above the water introduced a potential problem: oil could adhere to the camera lenses as the probe passed through it, affecting image clarity.<\/p>\n\n\n\n

\"AML921<\/figure>\n\n\n\n

Before contacting AIMOLI<\/a>, the customer had compared equipment from other manufacturers but remained concerned about unclear images and performance at greater depths.<\/p>\n\n\n\n

AIMOLI’s technical team conducted an internal simulated-condition test using its proprietary technology. The test results showed clear views of the well walls and well bottom under the simulated conditions. After reviewing the test videos and results, the customer approved the proposed solution. The project subsequently entered the procurement stage.<\/p>\n\n\n\n

This case study explains the customer’s requirements, the technical challenges, AIMOLI’s testing process, and the limitations that still need to be considered before field application.<\/p>\n\n\n\n

1. Customer Requirements: Clear Well Wall Imaging at 200\u2013300 Meters<\/h2>\n\n\n\n

The customer works in coal mine exploration and needed a downhole camera to observe conditions inside a well.<\/p>\n\n\n\n

During discussions with AIMOLI, the customer explained that the project required observation of the well walls, with the well bottom also needing to be inspected. The unusual oil-water structure made equipment selection more complicated than a standard downhole inspection.<\/p>\n\n\n\n

The main requirements were straightforward:<\/p>\n\n\n\n

    \n
  • Observation depth:<\/strong> The target water layer was approximately 200\u2013300 meters below ground.<\/li>\n\n\n\n
  • Primary inspection target:<\/strong> The well walls, with additional observation of the well bottom.<\/li>\n\n\n\n
  • Image clarity:<\/strong> The camera needed to provide clear images under the intended operating conditions.<\/li>\n\n\n\n
  • Oil layer interference:<\/strong> The probe had to pass through an upper oil layer before reaching the underlying water.<\/li>\n\n\n\n
  • Pressure resistance:<\/strong> The equipment needed to be suitable for the intended depth.<\/li>\n<\/ul>\n\n\n\n

    For this project, selecting a downhole camera based on maximum depth alone would not address the entire problem. The team also needed to consider whether oil contamination could affect the imaging lenses before the camera reached the target area.<\/p>\n\n\n\n

    2. Understanding the Well Conditions<\/h2>\n\n\n\n

    According to the information provided by the customer, the well had a distinctive oil-water stratification structure.<\/p>\n\n\n\n

    Project parameter<\/th>Reported condition<\/th><\/tr><\/thead>
    Distance from ground level to the oil surface<\/td>Approximately more than 100 meters<\/td><\/tr>
    Oil layer thickness<\/td>Approximately 30 meters<\/td><\/tr>
    Oil-water distribution<\/td>Oil above water because oil is less dense<\/td><\/tr>
    Target observation area<\/td>Approximately 200\u2013300 meters<\/td><\/tr>
    Main observation objective<\/td>Well wall inspection, with well-bottom observation<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

    These conditions created two separate considerations for the downhole camera.<\/p>\n\n\n\n

    First, the equipment needed to operate at the required depth under suitable conditions. Second, the probe would pass through the oil layer before entering the water layer, creating a potential risk of oil accumulating on the lens surfaces.<\/p>\n\n\n\n

    The second issue was particularly important because the customer wanted to inspect the well walls. If an oil film blurred the camera’s images, reaching the target depth would not necessarily deliver useful inspection results.<\/p>\n\n\n\n

    This is why the evaluation focused on both deep-well capability and the potential impact of oil layer interference on imaging performance.<\/p>\n\n\n\n

    3. Two Problems Identified During the Customer’s Equipment Comparison<\/h2>\n\n\n\n

    Before approaching AIMOLI, the customer had evaluated downhole inspection equipment from other manufacturers.<\/p>\n\n\n\n

    According to the customer’s feedback, two problems stood out.<\/p>\n\n\n\n

    Problem 1: Unclear Images Under Actual Well Conditions<\/h3>\n\n\n\n

    The customer reported that some previously evaluated equipment did not provide sufficiently clear images of the downhole environment.<\/p>\n\n\n\n

    For a project focused on well wall inspection, image clarity is essential. If the camera cannot clearly capture the well walls, the resulting footage may not provide the information needed for the inspection.<\/p>\n\n\n\n

    Problem 2: Limited Performance at Greater Depths<\/h3>\n\n\n\n

    The customer also reported concerns about pressure resistance and imaging performance.<\/p>\n\n\n\n

    Some devices could still monitor conditions at depths of 20\u201330 meters or 30\u201350 meters, but struggled to obtain clear and accurate images at depths exceeding 100 meters.<\/p>\n\n\n\n

    The customer’s target observation area was approximately 200\u2013300 meters, making this an important consideration during equipment selection.<\/p>\n\n\n\n

    The AIMOLI AML921 Digital Groundwater Downhole Camera can support applications at depths of up to thousands of meters under suitable operating conditions. This capability led the customer to contact AIMOLI to evaluate whether the equipment could meet the requirements of the specific project.<\/p>\n\n\n\n

    Actual operating depth and imaging performance depend on the equipment configuration and application conditions and should be confirmed for the intended installation.<\/p>\n\n\n\n

    4. The Main Technical Challenge: Oil Film on the Camera Lenses<\/h2>\n\n\n\n

    The most distinctive challenge in this project was the potential effect of the oil layer on the downhole camera’s imaging system.<\/p>\n\n\n\n

    As the probe descended, it would first encounter the oil layer. Oil could adhere to the bottom of the probe and the 360\u00b0 panoramic imaging lenses, potentially leaving an oil film on their surfaces.<\/p>\n\n\n\n

    After the probe passed through the oil layer and entered the water below, this film could affect light transmission and image formation, resulting in blurred footage.<\/p>\n\n\n\n

    For the customer, this created a practical concern: even if a camera could reach the required depth, would it still provide a clear view of the well walls after passing through the oil layer?<\/p>\n\n\n\n

    The team therefore needed to evaluate the potential effect of oil contamination rather than relying solely on the camera’s rated depth.<\/p>\n\n\n\n

    This type of assessment is relevant when selecting a downhole inspection camera for wells where oil, water, or other substances may affect the optical system. The actual effect depends on the specific media, equipment design, and operating conditions.<\/p>\n\n\n\n

    5. How AIMOLI Tested the Proposed Downhole Camera Solution<\/h2>\n\n\n\n

    Rather than relying only on product specifications, AIMOLI’s technical team conducted an internal simulated-condition test focused on the customer’s main concern: imaging performance under conditions involving potential oil layer interference.<\/p>\n\n\n\n

    The team used proprietary technology developed in-house to carry out the test.<\/p>\n\n\n\n

    The reported test results showed that the well walls and well bottom could be observed clearly under the simulated conditions. AIMOLI then provided the customer with the test videos and results for review.<\/p>\n\n\n\n

    After reviewing this material, the customer approved the proposed solution.<\/p>\n\n\n\n

    The test gave the customer a practical basis for evaluating the proposed equipment, rather than requiring the decision to be made solely from a specification sheet.<\/p>\n\n\n\n

    Test and validation note:<\/strong> The test described in this case study was conducted internally by AIMOLI under simulated conditions. It was not an on-site field test at the customer’s project location. The test results should not be interpreted as confirmation of performance under every actual well condition. The project’s real operating environment, oil characteristics, and other site-specific factors still require further assessment and validation.<\/p>\n\n\n\n

    This distinction matters when evaluating any specialized downhole camera: internal testing can provide useful evidence, but actual field performance must be assessed against the conditions in which the equipment will be used.<\/p>\n\n\n\n

    \"\"<\/figure>\n\n\n\n

    6. Project Status: Customer Approval and Procurement Discussions<\/h2>\n\n\n\n

    Following the internal test, AIMOLI shared the results and videos with the customer. The customer approved the proposed solution, and the project entered the procurement stage.<\/p>\n\n\n\n

    At the time of this case study, both parties were discussing the subsequent purchasing procedures. The case had not yet reached a confirmed completed-purchase or field-application stage.<\/p>\n\n\n\n

    The project illustrates why equipment selection for unusual well conditions should consider more than depth specifications. In this case, the customer’s decision also depended on the potential effect of oil contamination, the need for clear well wall imaging, and the test evidence provided by AIMOLI.<\/p>\n\n\n\n

    For projects with similar requirements, discussing the actual well conditions early and assessing the key technical risks can help determine whether a particular camera configuration is appropriate.<\/p>\n\n\n\n

    7. Choosing a Downhole Camera for Deep-Well Inspection<\/h2>\n\n\n\n

    A downhole camera should be selected according to the intended depth, the substances present in the well, and the inspection task.<\/p>\n\n\n\n

    For deep-well projects, the following points deserve particular attention.<\/p>\n\n\n\n

    Operating Depth and Pressure Resistance<\/h3>\n\n\n\n

    Confirm the required observation depth and the equipment’s rated operating limits under the intended conditions.<\/p>\n\n\n\n

    A maximum depth specification should not automatically be interpreted as a guarantee of identical imaging performance in every environment. The camera configuration, operating conditions, and project requirements must be considered together.<\/p>\n\n\n\n

    Oil-Water Conditions and Lens Contamination<\/h3>\n\n\n\n

    Explain whether the well contains oil layers, water, mud, or other substances that could affect the probe or lens surfaces.<\/p>\n\n\n\n

    For an oil well camera or downhole camera used in an environment with oil-water stratification, potential lens contamination should be assessed before deployment.<\/p>\n\n\n\n

    Well Wall and Well-Bottom Imaging<\/h3>\n\n\n\n

    Clarify whether the primary requirement is well wall inspection, well-bottom observation, or both.<\/p>\n\n\n\n

    If 360\u00b0 panoramic imaging is required, confirm that the selected equipment configuration supports the intended observation method.<\/p>\n\n\n\n

    Testing Under Relevant Conditions<\/h3>\n\n\n\n

    For unusual applications, discuss whether internal simulation testing or additional field validation is appropriate.<\/p>\n\n\n\n

    Providing accurate information about the well depth, oil layer thickness, target observation area, and expected imaging results helps the technical team assess the proposed solution more effectively.<\/p>\n\n\n\n

    AIMOLI can evaluate the AML921 Digital Groundwater Downhole Camera for different operating conditions and discuss customized solutions according to the specific application requirements.<\/p>\n\n\n\n
