Pressure and Pressure Derivative Analysis for Linear Homogeneous Reservoirs Without Using Type-Curve Matching

A Complementary Conventional Analysis for Channelized Reservoirs

“…Dimensionless reservoir width and well position, as sketched in Figure 1.a, Escobar et al (2004), are:…”

“…(8) Escobar et al (2004) and Escobar, Hernández, Y.A., and Hernández, C.M. ( 2007) have described the differences between the dual linear flow and the single linear flow occurring in elongated systems.…”

“…( 2007) have described the differences between the dual linear flow and the single linear flow occurring in elongated systems. Escobar et al (2004) found out that Equation 8 was mistaken, so they proposed a new equation to describe dual linear, and single linear as well, flow regimes, such as:…”

“…Among them, we can name Ehlig-Economides and Economides (1985), Massonet, Norris, and Chalmette (1993), Mattar (1997), Nutakki and Mattar (1982) and Wong, Mothersele, Harrington, and Cinco-Ley (1986). A better description of channelized systems and a detailed interpretation technique was presented by Escobar, Saavedra, Hernández, C.M., Hernández, Y.A., Pilataxi, and Pinto (2004) who classified the linear flow regime into two closely related names: "dual linear flow" and "single linear flow" regimes as sketched in Figure 1.b. When the well is off-centered with respect to the lateral sides, firstly, we observe two linear flow regimes coming from both lateral sides of the well.…”

“…Single linear flow can also be present when the well is located very close to one lateral boundary as shown in Figure 1.c. Escobar et al (2004) called this "single linear flow" or simply, "linear flow". However, if the closer boundary is at constant pressure, then "parabolic flow" develops and steady state follows this flow regime.…”
