... Abstract An approach to determine stress field near wellbore with existing hydraulic fracture accounting for rising pressure and fluid filtration along the crack has been developed. An estimations of secondary fracture initiation time near wellbore as well as moment of primary crack growth...

... on the TVDSS. Success of cluster MSHF was reported for some wells. Use of internal-flush cemented liners with targeted initiation of fractures shows good results in some areas. Subject to the quality cementing, this is the most strategically promising and anticipated approach for the repeated targeted MSHF...
