Entry and Exit Hole Analysis

DarkVision’s High-resolution Acoustic Downhole Evaluation System sets a new standard for well inspection and frac evaluation. HADES-R® captures submillimetric 3D point clouds of data of an entire well in a single pass, providing operators with unprecedented level of insight into downhole conditions - regardless of fluid clarity.

Direct 3D Measurements

Virtually Unplugged

The newest standard in downhole inspection is directly measuring the open hole areas of perforations at the wall ID and OD in 3D. During stimulation, the entry hole expands and rounds over as large volumes of proppant erode through the inner surface edges first before eroding through the perf and gradually growing the exit hole as it leaves the casing.

With DarkVision’s Advanced Entry and Exit Hole Analysis, even when one end of a perforation is obscured or plugged, the perforation can be virtually unplugged by correlating the ratio of entry-to-exit hole of the population of the perforations in the well or for a specific stage design. This means more perforations are analyzed and no flushing of perforations are required.

DarkVision’s High-resolution 3D Acoustic data provides operators with most complete and representative understanding of their wells.
