Paper Number: SPE-174188-MS
... Abstract The dimensionless parameter “skin” is commonly used to describe actual well performance with reference to an ideal case, and a number of analytical correlations have been derived over the years to account for the effect on well productivity caused by well geometry, completion design...

... of producers. The sand is unconsolidated and injectors are generally completed with stand-alone screens. Since drilling the first injector well in 1995 there has been an evolution in drilling and completion practices and while the original wells were drilled with non-aqueous drilling fluids, current wells...

Paper Number: SPE-174239-MS
... Abstract Efficient removal of the drilling fluid from tubulars, screens, and near-wellbore mineral surfaces is essential to the successful completion of wells. Cleaning and removal of the non-aqueous drilling fluid (NADF) from all of the well surfaces is not an easy task. Microemulsion fluids...

... The real problem with this theory is that significant variation can be observed in wells that are drilled in the same reservoir and with the same completion designs. In some cases, the results are drastically different; wells that are adjacent to each other, drilled in the same relative horizon...
