... it is vital with a continuous follow-up work of well testing and maintenance of multiphase meters. The Heidrun field also has many wells with challenges like; sand entrainment, drifting draw-down, limited draw-down or bottom hole pressure (BHP) and drifting GOR. These elements are crucial to control...

... that it is nearly "invisible" until the methane starts boiling out of the OBM in the riser, casing a possible domino effect after the BOP. This could dramatically reduce the bottom hole pressure during circulation. This paper will discuss the elements of computing methane diffusion rates in a well drilled with OBM...

... weight to drill depleted reservoirs. The technique also allows for precise control of wellbore pressures and enables drilling with close to constant bottom hole pressure. The technology will ensure improved hydraulics which can result in; improved hole cleaning, higher rate of penetration, improved...
