... Abstract Development of a tight reservoir characterized by low permeability poses significant challenges to the oil and gas industry due to the low productivity and the excessive costs. This study explores the potential of utilizing "Fishbone Wells" compared to multi-fractured horizontal wells...

... be as high as 100 kN. The more advanced rock mechanics model indicates there is a mechanism in an interval with fractured shales in Lower Hordaland formation where the problems occurred on the trips out. Fluid invasion into fractures, cyclic ECD pressure and gravity is driving the deformation. We see...

... of the treatment, the cell was submitted to cyclic loading of casing pressure with periodic permeability measurements. The leakage rate did not substantially increase after 80 cycles of radial casing expansion, but radial fractures in the cement may have been induced. This work presents a new experimental...

... of a successful squeeze cement job. The main objectives of this study are to determine the penetration potential of different cement blends; determine the critical gap width where bridging of cement particles starts and to compare the fracture conductivity of the sample before and after remediation.

... geoscientists visualize and understand the stratigraphy and fractures. A pulse radar operating in the multi-gigahertz range is implemented within the bottom hole assembly. As the BHA rotates, the radar measurements scan the borehole surface. The time of flight is converted to a distance to the borehole wall...

... Abstract Severe lost circulation occurs frequently in fractured and vugular media. When drilling fluid enters vugs or fractures, it experiences a temperature increase due to the reduced influence cooling from the wellbore and the growing influence of the higher in-situ formation temperature...
