What is claimed is: 1. A method for producing fluid from a well, comprising: determining a first setting of a first device using a processor wherein the first device is under use for producing the fluid from the well at a first flow rate; selecting a set of parameters using the processor, wherein the set of parameters includes a parameter relating to health of a second device and a plurality of parameters selected from a group comprising flow rate, pressure, temperature, presence of a selected chemical, water content, sand content, and chemical injection rate; determining a second setting for the first device using the processor, wherein the second setting that provides an increased life of the second device and a second flow rate for the fluid from the well relative to the first flow rate using the selected set of parameters as an input to a computer model, wherein the second setting is determined after the first setting; and storing the determined second setting on a suitable medium. 2. The method of claim 1 further comprising (i) operating the well corresponding to the second setting of the first device, and (ii) determining a performance of the well based on the determined setting. 3. The method of claim 2 further comprising: predicting an occurrence of one of: water breakthrough, cross-flow condition, breakdown of a device installed in the well; and determining the second setting based on such prediction. 4. The method of claim 2, wherein the second setting comprises at least one of: altering the chemical injection rate; altering an operation of an electrical submersible pump; shutting in a selected production zone; altering position of a choke; altering position of a valve; and altering flow through an artificial lift mechanism. 5. The method of claim 2 further comprising sending a message relating to the second setting to at least one of: an operator; and a remote location from the well. 6. The method of claim 2 further comprising using the processor that automatically sets the at least one first device to the second setting. 7. The method of claim 1, wherein the parameter relating to the health of the second device relates to at least one of: an electrical submersible pump; a valve; a choke; a casing lining the well; a pipe carrying the fluid from the well toward the surface; and a sand screen. 8. The method of claim 1 further comprising: estimating the second flow rate from the well over an extended time period based on the second setting; and estimating a net present value for the well corresponding to the estimated second flow rate for the extended time period. 9. The method of claim 1, wherein the group further comprises information relating to: resistivity; density of the fluid; fluid composition; a capacitance measurement relating to the fluid; vibration; acoustic measurements in the well; differential pressure across a device in the well; oil-water ratio; and gas-oil ratio. 10. The method of claim 1, wherein the group further comprises: microseismic measurements; pressure transient test measurements; well log measurements; a measurement relating to presence of one of scale, hydrate, corrosion, paraffin, and asphaltene. 11. A computer-readable medium that has embedded therein a computer program that is accessible to a processor for executing instructions contained in the computer program, the computer program comprising: instructions to determine a first setting of a first device while in use for producing a fluid from a well at a first flow rate; instructions to select a first set of input parameters that includes a parameter relating to health of a second device and a plurality of parameters selected from a group comprising information relating to flow rate, pressure, temperature, presence of a selected chemical, water content, sand content, and chemical injection rate; instructions to determine a second setting for the first device that provides at least one of an increased life of the at least one second device and a second flow rate for the fluid from the well relative to the first flow rate using the selected set of parameters, wherein the second setting is determined after the first setting; and instructions to store the determined second setting on a suitable medium. 12. The computer-readable medium of claim 11 wherein the computer program further comprises: instructions to send signals to operate the well corresponding to the second setting of the first device; and instructions to estimate a performance of the well based on the second setting. 13. The computer-readable medium of claim 11, wherein the parameter relating to the health of the second device relates to at least one of: an electrical submersible pump; a valve; a choke; a casing lining the well; a pipe carrying the fluid from the well toward the surface; and a sand screen. 14. The computer-readable medium of claim 11, wherein the computer program further comprises: instructions to estimate the second flow rate from the well over an extended time period based on the second setting; and instructions to estimate a net present value for the well corresponding to the estimated second flow rate for the extended time period.
