Effective control of vertical fracture growth by placement of an artificial barrier (Bottom Screen Out) in an exploratory well. SPE 69578
Language: Inglés Series: García, D.G ; Publication details: Dallas, Texas Society of Petroleum Engineers 2001Online resources: Summary: This operation was designed out of a need for hydraulic stimulation - whith no height increase - in a highly homogeneous medium with a water table (Sierras Blancas Formation, YPF.Nq.Bco x-3 ST well). From this, an artificial lower barrier was placed to control growth in the direction of the water and a crosslinked gel pad was pumped (followed by sand concentrations carried by a linear gel for sand settling) to give rise -upon fracture closure - to a dehydrated gel zone of poor permeability. Furthermore, a water inhibitor was used as an additive for improved water control. Furthermore, a water inhibitor was used as an additive for improved water control. As an additional advantage, Bottom Screen Out (BSO) pumping might result in an increased fracture length which in turn would lead to a better production response from stimulation, a "sine qua non" condition in low permeability reservoirs.| Current library | Status | Barcode | |
