Lunch will be available starting at 11:30am with the presentation following at or around noon.
During well intervention activities, one of the biggest challenges faced is uncertainty about the downhole hardware. Carrying out interventions without understanding the status of downhole equipment can be time-consuming, expensive and ultimately unsuccessful. Downhole X-ray diagnostics offer clear, quick, and reliable insight into what is happening in the well. The primary advantage of X-ray diagnostics is that the radiation can penetrate materials that are opaque to visible light, such as well fluids like oil and brine and some solid materials like cement and sediments.
This presentation will discuss the principles of the technique and how the X-ray diagnostic service is performed. To demonstrate its capabilities, we will provide case studies from wells in the North Sea, Middle East and North America involving diagnosing a malfunctioning downhole safety valve, milling whipstock, and fishing various hardware. In each case, the X-ray diagnosis resulted in more efficient interventions by providing the understanding necessary to choose the most appropriate course of action.
