... ABSTRACT Hydraulic fracturing (HF) treatments can form widespread fractures. Understanding their containment at depth is critical, given the positive buoyancy contrast between the fracturing fluid and the surrounding rock, promoting upward growth. We study arrest mechanisms for established...

.... Higher water injection pressure provided better pressure containment for the gas HnP well, but high water cut presented a detrimental effect on oil production. 1. INTRODUCTION The Bakken Formation has witnessed a boost in oil production since 2008. By the end of March 2022, the oil production...

... ABSTRACT: In this paper we present a new mechanism that explains hydraulic fracture containment in the target zone. The study is based on the modelling of hydraulic fracture propagation in weak rocks and comparison of the results of propagation in the vertical direction with propagation...

Observations and measurements of organic shales from unconventional reservoirs also showed abundance of weak interfaces present...

...1. INTRODUCTION Hydraulic fracture height containment in heterogeneous formation layers have been the subject of numerous studies. Whether an adjacent formation acts as a fracturing barrier depends on a number of factors: differences in horizontal in-situ stress, elastic properties, fracture...

..., and the fracture height is dominated by in-situ stress. Stress difference higher than 4MPa shows great effectiveness in fracture height containment. In addition, the result indicates that lower elastic modulus is favorable for fracture height containment while Possion’s ratio has almost no effect. Fracture...

A number of natural analogues where fluids have been contained in cavities under high pressure for millions of years support this picture. For waste disposal, one has to show...

These parameters are optimized to maximize hydrocarbon recovery and Conductive Reservoir Volume (CRV) and in the meantime fractures are contained within the target zones and subsurface integrity is maintained. This optimization, however, needs to be evaluated within the context...
