“…For example, interpretation of well testing results of a naturally fractured reservoir is carried out remarkably easier with the aid of pressure derivative (Cinco-Ley 1996). Interpreting of the transition period of naturally fractured reservoirs is an obstacle which many analyzers tackle with (Aguilera 1987;Feng et al 2016;Seyedi et al 2014). Many authors applied this period for different models of naturally fractured reservoirs and their corresponding pressure transient analyses published in the literature (Dejam et al 2018;Aguilera 1987;Najurieta 1980;Warren and Root 1963;Odeh 1965;Kazemi 1969;Kazemi et al 1969;de Swaan 1976;Aguilera and Song 1988;Kuchuk and Biryukov 2014;Al-Rbeawi 2017).…”

Well testing is one of the important methods to provide information about the reservoir heterogeneity and boundary limits by analyzing reservoir dynamic responses. Despite the significance of well testing data, misinterpreted data can lead us to a wrong reservoir performance prediction. In this study, we focus on cases ignoring the adjacent well's production history, which may lead to misinterpretation. The analysis was conducted on both homogeneous and naturally fractured reservoirs in infinite-acting and finite-acting conditions. The model includes two wells: one is "tested well" and the other is "adjacent one." By studying different scenarios and focusing on derivative plots, it was perceived that both reservoir and boundary models might be misinterpreted. Additionally, in all cases, a sensitivity analysis was performed on parameters affecting interpretation process. Studying the literatures, few articles have focused on drawbacks during diagnostic plot interpretation and also the effect of adjacent wells. Hence, these issues were addressed. Overall, considering several cases it was proved that neglecting the production effect of adjacent wells causes wrong interpretation, and this should be avoided in all interpretation cases. Regarding the importance of reservoir characteristics and its flow regime, any wrong interpretation may create huge uncertainties in the reservoir development. As a result, this paper aimed to address the well testing, especially in brown fields where the production of other wells may affect the pressure response of the tested well; therefore, it will be pivotal to consider the effect of adjacent wells' production history.
