... Abstract Hydraulic fracture initiation can be a challenging issue for fracturing deep and tight gas reservoirs, which generally requires a high breakdown pressure for clustered perforation hydraulic fracturing treatment. Oriented perforation represents a potential solution to alleviate...

... of a hydraulic fracture in the absence of proppant. These solutions are relevant in the context of micro hydraulic fracturing tests for in-situ stress determination. In this work, we report a laboratory hydraulic fracture experiments performed in sandstones with the aim to study experimentally fracture closure...

... hydraulic fracture simulation geomechanical mesh Abstract An integrated and multiscale analysis has been performed to ensure safe reinjection of formation water into a sandstone saline aquifer during the lifecycle of an onshore field. The study includes well centered models to evaluate...

... ABSTRACT: Rock is a typically heterogeneous material composed of inherent microstructures at the grain scale, which has a significant effect on the behavior of hydraulic fractures. This paper employs the grain-based DEM coupled with pore network model to capture the interaction behavior between...

... and Enhanced Oil Recovery (EOR) or hydraulic fracturing (HF) of shale gas and shale oil formations using super-critical CO2 are technologies gaining more attention recently for environmental and energy efficiency considerations. In low-permeability HDR or shale formations, HF may further stimulate energy...

...1. INTRODUCTION Hydraulic fracturing technology has brought us a lot of economic and societal benefits because it makes the extraction of oil, gas, and heat from low permeability rocks possible. However, the accurate design of efficient well treatment operations to create sustainable stimulated...
