... even more critical when dealing with offshore horizontal wells with ESP systems installed. A wide selection of proppant flowback prevention additives is now available in the industry: most of them work either chemically or mechanically. At low formation temperature (150 F), the effectiveness of some...

Interpretation of many production logs run in horizontal wells is a difficult, if not impossible, process. Many events occur along...

... Abstract This paper describes the development of a tight gas reservoir in the Dutch sector of the Southern North Sea, using a horizontal well with 5 hydraulic fractures. The reservoir is tight (average permeability below 0.1 mD) and was discovered in 1986. The first development well was drilled...

... Abstract Recent studies show that the flow along a horizontal well is not uniform or symmetrically distributed, as a larger volume of fluid enters the well near the heel. Flow equalization in horizontal wells is a state of the art strategy for assuring effective reservoir drainage and delaying...
