AQUTAB

Recognised by the OPM Flow parserPROPS

The AQUTAB keyword defines additional Carter-Tracy175 Carter, R. D., and Tracy, G. W. “An Improved Method for Calculating Water Influx.” Transactions of AIME, Vol. 219 (1060), pp 415-417. aquifer functions to be used in the model. Carter-Tracy representation of the aquifer influx is via a qw term in the non-linear aquifer influence function Q(t). It allows the water influx from the aquifer to be represented in the simulator by assuming that there is a constant water influx rate over finite time periods. It is derived from the superposition methods of van Everdingen and Hurst176 Van Everdingen, A. F., and Hurst, W. “The Application of the Laplace Transform to Flow Problems in Reservoirs.” Transactions of AIME, Vol. 186 (1949), pp. 305-324., whose superposition methods are not suitable for implementation in reservoir simulation software, although they are very useful in interpreting aquifer response. The storage requirements and calculation complexity of handling the resulting superposition formulae can be largely eliminated by use of the Carter-Tracy approximate water influx method.

Notes:

The keyword is followed by NIFTBL tables as declared on the AQUDIMS keyword in the RUNSPEC section.

Each table must contain at least two complete rows with a maximum of NRIFTB rows as declared on the AQUDIMS keyword in the RUNSPEC section. Note that NRIFTB must not be less than 36 in order to accommodate the default infinite acting Carter-Tracy aquifer influence function.

Each table is terminated by a “/” and there is no “/” terminator for the keyword.

Note

OPM Flow includes the infinite acting Carter-Tracy aquifer influence table as a default for table number one; thus data entered on this keyword starts from table number two.

Table 8.19to Table 8.22outline the standard finite tables derived by van Everdingen and Hurst that are used for the Carter-Tracy analytical aquifers and are taken from Bradely177 Bradley Howard B., et al., Petroleum Engineering Handbook, Society of Petroleum Engineers (June 1989), ISBN:9781555630102. table 38-6 on page 38-12. In the tables rD is defined as the ratio of the aquifer external radius divided by hydrocarbon radius, that is:[r sub {D} ~=~ r sub{e} over {r sub{o }}]..
