... ratios for a two-phase mixture. Effect of flow regime on SoS In the interpretation of measured SoS within a two-phase system, precise specification or estimation of flow patterns is crucial as the characteristics of excitation forces depend on these patterns. Several maps have been developed to estimate...

..., such as porosity, saturation, well spacing, and fracture designs, to evaluate their impact on the b-factor. In theory, the b-factor changes with time and flow regime. Specifically, it transitions from a value of 2 during linear flow to less than 1 during boundary flow. However, in practice, a constant b-factor...

Another common method, RTA, is interpretive and unsuitable for field-scale applications due to the need for flow regime identification and mechanistic assumptions. This study aims to develop...

After the experiment, the treating pressure, injection rate, and DSS data are comprehensively analyzed to quantitatively characterize the fracture geometry over time. The fracture width is interpreted using DSS data, and the regimes of fracture propagation...

...-length and height. This information allows operators to optimize hydraulic fracturing treatment design and achieve the desired production results. Accurately predicting and modeling hydraulic fracture geometry can be challenging due to several factors, such as complex stress regimes in subtly different...

... the discrepancies in flow regimes frequently seen between buildup test and drawdown log-log diagnostic plots obtained from Rate Transient Analysis (RTA). These occur because the effect of the extended drawdown is stronger and occurs earlier in unconventional wells than in vertical wells with radial flow...

... Abstract Development of fractured horizontal wells stems from the industry’s need to optimize production from unconventional plays characterized by low permeabilities. Continual improvements have led to complex fractures with reduced fracture spacing and clear flow regimes showing a transition...

The method also enables the identification of dominant flow regimes by using terms with the highest contributions instead of the usual line fitting procedure. Traditional methods like RTA tend to be interpretive and not suitable for field...

... and boundary dominated flow a slope of 1. In a typical case a slope of 0.7, for example, is clearly stablished and lasts months to years. This power-law flow regime is well documented (Chu et al., 2017) and it is often called transitional flow (Apte and Lee, 2016). It has been described as a deviation from...

Currently no field test exists that can capture the dynamic behavior of the conductivity. Bilinear flow analysis (¼-slope flow regime) is a common rate-transient-analysis (RTA) technique...

... Abstract Flow regime changes are important to capture and predict when estimating the future production from tight oil wells. Due to the nature of hydrofracture completions and reservoir heterogeneity, flow regimes are difficult to predict before they are observed. Also, while some wells...

In fact, we observed the relationship between oil rate and gas rate to be governed by a power-lower function for a given flow regime after GOR breakout. This allowed us to use a Log-Log plot...
