Three-dimensional multi-level fracture propping technique for full-domain propped fracturing: A case study of shale oil and gas reservoir stimulation

Petroleum Exploration and Development
Effective propping of multi-stage fractures is challenging in shale oil and gas reservoirs stimulated by full-domain propped fracturing. This paper discusses the three-dimensional multi-level fracture propping technique, a component of the full-domain ...

Determination of Hydraulic Properties of a Large Self-Propped Hydraulic Fracture in the Geothermal Research Borehole Horstberg Z1 in the Northwest German Basin

Geofluids, 2019
The pressure records of an interference test on a huge hydraulic fracture in a layered sedimentary rock formation of the Northwest German Basin were analysed in order to determine fracture transmissivity and fracture storage coefficient. The fracture had

Displacement Estimation of Structures With Flag‐Shaped Hysteresis Loops

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Time‐history analyses were conducted on single‐degree‐of‐freedom (SDOF) systems with flag‐shaped hysteresis loops using a far‐field ground motion suite to estimate peak displacements, Δp, and equivalent deformation cycles, Nc, associated with cumulative displacement demands.

Fracture cleaning: experimental study on the unclogging process within a propped fracture under a dynamic stimulation

, 2020
Submitted to the Journal of petroleum science & engineeringDynamic excitation of a clogged fracture can increase its permeability. Pressure oscillations inside the fracture are expected to flush out the fine particles blocking the flow.
