Using Inflow Control Devices (ICD) in SAGD Recovery of Heterogeneous Athabasca MCMurray Oil Sands
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.
The EDF schedule algorithm,one of main real-time schedule algorithms of the embedded Linux operating system,can not solve the overload schedule.For this,the paper introduces SLAD algorithm and BACKSLASH algorithm,which have good performance of system load.According to thinking of ISM algorithm,it puts forward a kind of dynamic priority schedule algorithm.According to case of overloads within some time,the algorithm can adjust EDF algorithm and SLAD algorithm neatly,thus improves schedule efficiency of system in usual load and overload cases.Test results for real-time tasks Deadline Miss Ratio(DMR) show its improvement effect.
