A hybrid GMT-PO method for calculating the NDC of the irregular edge of a semi-infinite circular cylinder
In this paper, the GMT–PO hybrid method accompanied by the iterative technique is applied successfully to calculate 3-D numerical diffraction coefficients (3-D NDC) of the irregular circular-cylinder edge. The computed RCS of the circular cylinder with 3-D NDC of the irregular edge is in good agreement with the measured data from the reference. © 2001 John Wiley & Sons, Inc.

Summary In the pilot study, a new geomodeling technology is presented for developing 3D heterogonous geomodels for Athabasca McMurray (MCMR) oil sands. The geomodels were used to simulate SAGD thermal recovery. Both conventional SAGD completions and SAGD with ICD completions were tested. The simulation results show that for a heterogeneous Athabasca McMurray oil sand reservoir, the ICD completion technology enhances oil production and reduces steam consumption. As a result, the economics of SAGD recovery from the heterogeneous sands is improved.
