... Abstract Hydraulic fracturing is more popular, due to its revolutionary impact in the US oil industry, especially in unconventional reservoirs. This paper first presents the analysis of hydraulic fracturing treatments in 56 vertical and horizontal wells in the Wolfcamp and Spraberry formations...

... system (RSS) steering mechanism on wellbore tortuosity in horizontal wells. Wellbore tortuosity in drilling applications is defined as any unwanted deviation from the planned well trajectory. As reservoir objectives become more complex and exact, operators increasingly perceive the wellbore tortuosity...

... Abstract Production logging analysis in horizontal wells can be very challenging due to the fluid distribution and segregation. In addition to this, other factors such as the presence of heavier or viscous fluids, wells with debris or sticky materials add to the complexity of the downhole fluid...

... ). The horizontal well's horizontal-section length usually ranges from 800m to 2500m. In general, the horizontal-section length ranges from 900m to 2000m in the United States ( Fang, 2013 ; Lin and Wang, 2014 ; Ai, 2015 ). In 2016, Halliburton and Eclipse worked together to complete the drilling operation...

... advantages by using dissolvable frac plug is that the milling-out operation conducted in traditional plug is no more necessary, which significantly reduces the costs and risks of plug removal. Weiyuan shale gas field is located in the southwest of China, most platforms have three-six horizontal wells...

... unleashing the limitation of wellbore finite conductivity, a U-shaped horizontal well design is investigated in this study. The U-shaped well architecture is new but was not studied from the flow capacity drivers, was hence was not considered as a solution for optimizing the flow in extended reach wells...

... Abstract Fractured horizontal wells are widely used to produce tight oil. But different fracture patterns could be generated in different reservoirs, which results in different well performances. How to identify the flow regimes and their impacts on performance is still challenging. This paper...

... Abstract Most of horizontal wells was completed with uncemented screens to prevent from sand production in some oilfields near Bohai Bay east China. In recent years oil production of the wells have begun to decline due to water out of the wells, especially water rates in part of the wells were...

The discrete fracture model efficiently and accurately coupled the flow mechanisms in matrix and fractures ( Sun and Schechter 2015a , Sun and Schechter 2015b , Sun, Schechter et al. 2015c ). Some fluid flow from matrix to fracture...

... carbonate field presents several challenges. Most of the horizontal wells drilled in such fractured reservoirs suffer from early gas or water breakthrough because conductive fractures dominate the influx from the reservoir and cause an unbalanced flux profile along the wellbore.
