Regular pressure testing of well barriers is a vital contributor to well integrity and safety. Greenlight employs digital technology in a compact user-friendly platform to consistently approve or reject pressure tests against predetermined test criteria—objectively and accurately. Traditional testing methods utilize equipment that can be cumbersome to install and operate, but crucially may rely on devices such as rotating chart recorders. First patented in the late 19th century, chart recorders have several drawbacks—the recording range is restricted by the fixed diameter of the paper chart, but more importantly, resolution and sensitivity restrictions limit the precision and effective accuracy of displayed results. The need to visually interpret the chart compounds this issue—bringing an element of subjectivity in determining if the test criteria have been fully met. This can result in uncertainty and the risk of undetected failures.
