Multi-Phase Rate Transient Behaviors of the Multi-Fractured Horizontal Well With Complex Fracture Networks

Youwei He et al.

Summary: This study investigates the impact of complex fracture networks (CFN) on multi-phase rate transient behaviors in unconventional reservoirs and analyzes when multi-phase models should be used for more accurate results. The results show that there are significant deviations between multi-phase and single-phase models, and a combination of different analysis curves can improve the interpretation accuracy.

Modeling transient pressure behaviour of a multi-fractured horizontal well in a reservoir with an arbitrary boundary and different fracture networks by considering stress-sensitive effect

Yunhao Zhang et al.

Summary: This paper proposes a semi-analytical model to evaluate the pressure behavior of multi-fractured horizontal wells in naturally fractured reservoirs. The study examines the effects of stress-sensitivity in matrix and fracture subsystems, as well as the convergence-skin effect near the wellbore. The model has been verified and extended for field applications, providing insights on well production and hydraulic fracturing design optimization.

A semi-analytical pressure model of horizontal well with complex networks in heterogeneous reservoirs

Zhun Li et al.

Summary: This paper presents a rigorous semi-analytical model for horizontal wells with complex fracture networks in heterogeneous reservoirs, considering the heterogeneity of the reservoir and differences between the stimulated and unstimulated regions, as well as complex fracture geometry. The research results have significance for well test interpretation of tight reservoirs.

Pressure Response of a Horizontal Well in Tight Oil Reservoirs with Stimulated Reservoir Volume

Peng Chen et al.

Summary: This study focuses on the analysis of fracture network in a horizontal well with a stimulated reservoir volume, showing that parameters of hydraulic fractures mainly affect the early stage of pressure behavior while the stress-sensitive effect mainly affects the middle and late stages. Different flow regimes include bilinear flow, linear flow, crossflow, and radial flow controlled by properties of the fractured area.
