Conjugate-gradient-like (CGL) methods were used to solve the matrix equations for several large field and fine grid models. The methods used ILU or MILU preconditioning coupled with Orthomin acceleration. The CGL methods were applied to the original matrix or to a reduced system from alternate diagonal ordering. Test results from a black oil model with fault throws, a fractured reservoir model, and three steamflood models are given. It was found that the CGL methods are effective for solving the matrix equations. A more powerful preconditioner improves reliability but may use more CPU time. Guidelines for selecting the most effective method are provided.
