“…Behrenbruch and Biniwale (6) have shown the use of the C-K equation offers further insight into rock pore structures and depositional environments. However, the first more practical petroleum engineering applications using distinct zones (hydraulic units), providing information about depositional and diagenetic controls on pore geometry, were given by Amaefule and Barr (3,7) .…”

“…While in many instances, practitioners have used the C-K equation in a more mechanistic manner, to identify rock similarities, Behrenbruch and Biniwale (6) have presented a more systematic approach in analyzing flow zone units. They have proposed a classification framework, emphasizing the importance of properly integrating geological knowledge, for clastic formations that may be generally applied.…”

Laboratory derived capillary pressure data can be seen as an important tool for the purpose of establishing water saturationheight relationships as a function of rock type, forming the basis for a number of petroleum engineering and geoscience estimates. A modified 'FZI-λ' method, capable of giving better estimates of fluid distribution for Australian reservoirs, is proposed. The new methodology is particularly well suited for interpolating among different lithologies and diverse rock types as evident from a comparison with other methods reported in the literature, using a case study of the Griffin area fields.Reconciliation of capillary pressure data with core and log data can be advantageous for better reservoir description. In this work, the Carman-Kozeny (C-K) equation based Hydraulic Flow Zone Unit (HU or FZU) methodology has been found ideal in characterizing geologic depositional environments and modelling fluid saturation profiles. For this purpose, the concept of 'Global Characteristic Envelopes' (GCEs) has been introduced, to analyse geological and petrophysical characteristics and for the integration and correlation among the wells. Capillary pressure data, based on such FZU and depositional grouping, may be further used for modeling saturation profiles over the uncored intervals and allows meaningful averages to be assigned for geocellular modeling and reservoir simulation.

“…It should be noted that FZI is also a measure of grain size and the determination of this parameter for each plug , as well as its variation with depth are very indicative of quality changes for a particular formation interval. For some interesting case histories untilising the above mentioned methodology see for examples [7] [8] [9]. To determine the actual relationship for a chosen interval, all data points for the interval are plotted on a log(RQI) versus log(PG) graph.…”

Reservoir quality from cored intervals has traditionally been described by grouping similar intervals according to rock type. The main shortcoming of this static modelling approach is that it lacks clarity and it is not conducive for setting up a dynamic simulation model. The alternative is to use a modelling approach based on Hydraulic Flow Zone Units (HFZUs). First proposed in the late 1980s and extensively published in the early 1990s such formulation uses the well-known Carman-Kozeny (C-K) equation. More recently, this approach has been extended to cover a wider range of geological formations with diverse pore structure types. In using a HFZU approach, a preprocessing step is customarily undertaken to first overburden correct the data and where necessary also to correct for the Klinkenberg effect (lower permeability formations, lab testing with gas). The study presented compares corrected and uncorrected data sets, to see if correction alters the overall outcome of HFZU analysis. Specifically, data sets are compared at three different conditions: ambient, overburden (only) corrected and finally data that has been corrected for both, overburden and Klinkenberg effects. In all cases it is the Flow Zone Indicator (FZI), an index representative of formation quality that is tracked, together with the type of relationship. Several comparative analysis examples are given for diverse formations. The results show that uncorrected data can yield a different correlation and FZI, especially for intervals that include low permeability samples. Results indicate that Overburden and Klinkenberg corrections should be applied before HFZU analysis.
