... and allow injection of the desired rates resulting in more effective acid stimulation works. To overcome injection rate limitation during stimulation, a new valvular conduit flow profile was tested for ICD application. It relies on dynamic diversions and collisions of the fluid flow in series to provide...

...; and determine major factors lead to drillstring collision with wellbore. Drillstring vibration mechanisms are reviewed from literature to identify type of drillstring vibration responsible for wellbore failure. Then, drillstring equations of motion are solved utilizing Runga-Kutta numerical scheme...

... Abstract As offshore drilling grows more crowded and more complex, greater emphasis is placed on avoiding collisions with offset wellbores. The implications of a collision with an existing well are very real, and care must be taken to minimize the risks associated with such incidents. Collision...

..., and the effective area of well's inflow. A simple model of "bifurcated flow" was developed to demonstrate the effect of two phase flow baffling in granular porous media. The model shows that the change of flow momentum of the two fluids at collisions with rock grains becomes the major factor causing water...

... It must be recognized that a numerical estimate of collision probability is no better than the data from which it is derived. While a sound mathematical computation of probability is helpful, it also requires accurate knowledge of the magnitude and distribution of survey errors; this knowledge...

... unidentified, possibly to occur later if overrides were initiated during tripping. The rig could not function the PHM without using safety interlock override mode. Operation in this mode was both slow and dangerous. Collision with the drill floor was possible without the safety interlocks. Approach...

... of drilling close rules to help prevent well collisions in these congested offshore production areas. This paper summarizes the evolution of the Company's collision avoidance work from the introduction of drilling close rules in the early 1980's to the present. Over this period Dubai Petroleum has moved from...
