“Managed Pressure Drilling: Successful techniques to drill difficult wells, particularly in deep waters.”
The SPE Student Chapter of Technical University of Crete – School of Mineral Resources Engineering- is happy to invite you to our next online event titled “Managed Pressure Drilling: Successful techniques to drill difficult wells, particularly in deep waters.” on Tuesday, April 12th , at 18:00 (GMT+2) on Zoom.
The webinar will be presented by Dr. Vassilios C. Kelessidis, Drilling Engineering expert and Energy Consultant.
The seminar is an overview of the theory and applications of techniques termed ‘managed pressure drilling’ (MPD). These are very good and very efficient drilling techniques, essential for drilling difficult wells, especially deep-water wells, which can be of particular relevance to the long awaited upcoming deep-water drilling in Greek waters. Conventional drilling is an open system, where the drilling fluid (mud) is pumped down the hole returning with the cuttings to the open atmosphere and to the mud tanks, where it is ‘cleaned’ and it is returned to the well. Any undetected mud losses into the well or any undetected influx of subsurface fluids (gas, oil, water), which is the nightmare of the driller, may be detrimental to the safety of the crew and of the well. MPD, the suite of managed pressure drilling techniques, aims to minimize such problems by giving the driller the necessary tools to dictate himself what pressure is applied along the wellbore thus enhancing well safety.
In the seminar we will present the drivers for the development and application of these techniques, the advantages, limitations and key issues in applying such technologies. Furthermore, we will describe the different techniques of MPD, the equipment used, the risks associated and the procedures of how to select which particular technique to apply. All these will be achieved through presentation of the theory behind it, and analysis of case studies.
