Slickline Memory Camera
|
||
|
The slickline memory camera enables operators to obtain downhole images on slickline when the cost or logistics of mobilizing an electric line unit or fiber optic unit are prohibitive. This tool is time programmable and captures fifty images per trip into the well. It is designed to view many of the same mechanical inspection applications as Hawkeye II but because it lacks continuous surface read out and has limited memory, it is limited to viewing a single obstruction, restriction, fish, or hole. The tool has provided excellent results in a diverse set of circumstances. The operator can program the tool to take all 50 pictures consecutively providing a 1-1/2 minute HawkEye video, or program the tool to selective take some pictures at distinct time intervals. |

The image on the left was obtained using the DHVI Slickline
Memory camera. It shows the top of parted tubing 2-7/8 inches in 5-1/2
inch casing. The camera is in gas and the depth is 20 feet from the wellhead.
Prior to obtaining the image, slickline operations were hindered from
descending past 20 feet. The camera shows two shards of the fish covering
the top preventing tools from entering the fish. Slickline swedges were
deployed to hammer out the shards and the camera was rerun for a post
view of the results.

The image from the post view shows the effect of the swedging
operation was very clean and successful allowing a safe descent for other
tools and ensuring no hangups on tools at the top of the fish on the way
out with tools.
