On Geometric Correction Method of BJ-1 Panchromatic Image Covering Kingdom of Lesotho
The purpose is to find a suitable geometric correction method of BJ-1 panchromatic image covering Kingdom of Lesotho. The methods are carrying out two geo-correction experiments based on the push-broom model and the projective transform model for BJ-1 small satellite real panchromatic covering flat and mountain area of Lesotho. Results show that the projective transform model has equal or higher accuracy compared to the push-broom model. Conclusion is the projective transform model can be used in producing land use image map.
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.
