... the differences between analysis of buildup or falloffs following short and long flow periods. After covering pressure transient testing, we discuss rate transient diagnostic plots and the ambiguity observed during analysis of multifractured horizontal wells diagnostic plots and the uncertainty of analyst...

... Abstract In this paper the simplified way is proposed for predicting the dynamics of liquid production and estimating the parameters of the oil reservoir using diagnostic curves, which are a generalization of analytical approaches, partially compared with the results of calculations on 3D...

... could exist such as liquid loading. Decline rates used in practice to switch to exponential b -factor=0 varies from 5% to 10%. Application of Multiple Diagnostic Plots This study conducted rate transient analysis of Bakken and Permian shale MFHWs. About 500 MFHWs with minimum production...

..., special diagnostics of the multi well interference models will be required to differentiate between the boundary and interference effects. In addition, there is no analytical method for a well in a multi-well reservoir with no flow boundary condition. In this paper a new method was developed to model...

... Abstract Various diagnostics plots related to examining injection pressure gradient requirements for maintaining injectivity have been used in waterflood management. Among these plots, Hall plots and the derivative of Hall plots are the most common approaches used in the industry. This paper...

... simulation study was conducted to upscale the reported experimental-studies outcomes to the field conditions. As a result, different forward diagnostic plots have been generated from different combinations of CO 2 physical mechanisms with different shale-reservoirs conditions. Secondly, different backward...

.... A hybrid of early transient and later BDF models proves to be a reasonable solution to the forecasting problem in LRS. In addition, use of diagnostic plots (like log-log rate-time and log-log rate-material balance time plots) improves confidence in flow regime identification and production forecasting...

... Abstract The new diagnostic plots technique is proposed to evaluate four key gel gas shut-off treatments conducted at Prudhoe Bay last year. The diagnostic plots determined that a permeability contrast or formation channeling was the main mechanism for large gas entries. A log-log plot of Gas...

... Abstract Petroleum engineers widely use Chan water control diagnostic plots to visually examine patterns for mechanisms behind excessive water production in petroleum wells. Distinct signatures reveal constant water-oil ratio (WOR), normal displacement of oil by water, multilayer channeling...

... Abstract The conventional log-log diagnostic plot with pressure change and derivative with respect to the superposition time function has been applied with tremendous success in diagnosis of reservoir behavior by giving the buildup pressure response a shape similar to that of the drawdown...
