Paper presented at the SPE European Formation Damage Conference and Exhibition, June 3–5, 2015
Paper Number: SPE-174189-MS
... Abstract Formation Damage caused during drilling can have a significant impact on the near wellbore and the ability for a well to deliver to design. The reduction in near wellbore permeability is generally interpreted as a negative and the damage is normally minimised through careful selection...

... not adhered to. These include loss of injectivity, out-of-zone injection, early water breakthrough, loss of reservoir containment, significant CAPEX/OPEX overruns, injector-producer shortcircuiting, reservoir souring and scaling issues etc. Understanding of formation damage is one of the overarching...

Paper Number: SPE-174175-MS
... Abstract Reservoir drill-in fluids are specifically designed to avoid excessive fluid penetration and solid invasion into production zones so as to minimize formation damage. With wellbore temperatures increasing, the drive to develop thermally stable drill-in fluids has increased dramatically...

... depth of 2303 m. If the originally drilled wellbore would have been opened, the well would probably not even have started to flow, as a cylindrical hole inside a sealing cement section would have been created. Abstract Formation damages caused by the invasion of drilling and workover fluids into...

... compared with an “ideal” vertical well, and this will often mask the contribution of any formation damage along the horizontal section. This “negative skin” concept is somewhat misleading and often mis-conceived as the well productivity and inflow potential could still be reduced by formation damage...

... price of guar rose up significantly in 2011 and 2012. Shaken by the price run-up and the formation damage, companies started to look for alternatives. Towards the end of 2012, the guar price dropped; but it was still higher than 2010. Another problem with guar polymers is that guar gum can cause...
