1. A method of producing fluid from a formation, the method comprising: detecting impending condensing conditions for a reservoir impairing substance which is present in the fluid, wherein a first densitometer is positioned upstream of a flow restriction, and a second densitometer is positioned downstream of the flow restriction, whereby the impending condensing conditions are indicated by a change in density of the fluid as the fluid flows through the flow restriction; andautomatically adjusting a flow control device in response to the detecting, thereby preventing the reservoir impairing substance from condensing in flow passages within the formation and in a wellbore intersecting the formation during production of the fluid. 2. The method of claim 1, wherein the fluid comprises a hydrocarbon gas. 3. The method of claim 1, wherein multiple flow control devices regulate flow of the fluid from multiple respective zones of the formation, and wherein each of the flow control devices independently operates in response to the detecting. 4. The method of claim 3, wherein the detecting is performed at each of the multiple zones, and wherein each of the multiple flow control devices operates in response to the detecting at a corresponding one of the multiple zones. 5. The method of claim 1, wherein the impending condensing conditions are indicated by an increase in density of the fluid. 6. A method of flowing fluid from a formation, the method comprising: sensing presence of a reservoir impairing substance in the fluid flowed from the formation; andautomatically controlling operation of at least one adjustable choke in response to the sensing of the presence of the substance, wherein a first densitometer is positioned upstream of a flow restriction, and a second densitometer is positioned downstream of the flow restriction, whereby the sensing of the presence of the substance is indicated by a change in density of the fluid as it flows through the flow restriction. 7. A well system, comprising: at least one sensor which detects impending condensing conditions for a reservoir impairing substance which is present in a fluid being produced from a subterranean formation, wherein the at least one sensor comprises a first densitometer positioned upstream of a flow restriction, and a second densitometer positioned downstream of the flow restriction, whereby the impending condensing conditions are indicated by a change in density of the fluid as the fluid flows through the flow restriction; andat least one flow control device which automatically regulates flow of the fluid into a wellbore intersecting the formation in response to detection by the sensor of the impending condensing conditions, thereby preventing the reservoir impairing substance from condensing in flow passages within the formation and in the wellbore during production of the fluid. 8. The system of claim 7, wherein each of multiple flow control devices regulates the flow of the fluid from a respective one of multiple zones of the formation in response to the detection by a respective one of multiple sensors. 9. The system of claim 7, wherein the fluid comprises a hydrocarbon gas. 10. A well system, comprising: at least one sensor which detects impending condensing conditions for a reservoir impairing substance which is present in a fluid being produced from a subterranean formation, wherein the sensor senses light scattered by the substance, wherein the at least one sensor comprises a first optical fiber which launches the light and a second optical fiber which receives the light, and wherein the second optical fiber is not on a same axis as the first optical fiber, and wherein the at least one sensor comprises a first densitometer positioned upstream of a flow restriction, and a second densitometer positioned downstream of the flow restriction, whereby the impending condensing conditions are indicated by a change in density of the fluid as the fluid flows through the flow restriction; andat least one flow control device which automatically regulates flow of the fluid into a wellbore intersecting the formation in response to detection by the sensor of the impending condensing conditions, thereby preventing the reservoir impairing substance from condensing in flow passages within the formation and in the wellbore during production of the fluid. 11. A method of producing fluid from a formation, the method comprising: detecting impending precipitation conditions for a reservoir impairing substance in solution with the fluid, wherein a first densitometer is positioned upstream of a flow restriction, and a second densitometer is positioned downstream of the flow restriction, whereby the impending precipitation conditions are indicated by a change in density of the fluid as the fluid flows through the flow restriction; andautomatically adjusting a flow control device in response to the detecting, thereby preventing the reservoir impairing substance from precipitating in flow passages within the formation and in a wellbore intersecting the formation during production of the fluid. 12. The method of claim 11, wherein the fluid comprises a hydrocarbon liquid. 13. The method of claim 11, wherein multiple flow control devices regulate flow of the fluid from multiple respective zones of the formation, and wherein each of the flow control devices independently operate in response to the detecting. 14. The method of claim 11, wherein the detecting is performed by multiple sensors, and wherein each of the multiple flow control devices operates in response to the detecting by a corresponding one of the sensors. 15. A well system, comprising: at least one sensor which detects impending precipitation conditions for a reservoir impairing substance in solution with a fluid being produced from a subterranean formation, wherein the at least one sensor comprises a first densitometer positioned upstream of a flow restriction, and a second densitometer positioned downstream of the flow restriction, whereby the impending precipitation conditions are indicated by a change in density of the fluid as it flows through the flow restriction; andat least one flow control device which automatically regulates flow of the fluid into a wellbore intersecting the formation in response to detection by the sensor of the impending precipitation conditions, thereby preventing the reservoir impairing substance from precipitating in flow passages within the formation and in the wellbore during production of the fluid. 16. The system of claim 15, wherein the flow control device automatically regulates the flow of the fluid in response to the detection. 17. The system of claim 15, wherein each of multiple flow control devices regulates the flow of the fluid from a respective one of multiple zones of the formation in response to the detection by a respective one of multiple sensors. 18. The system of claim 15, wherein the fluid comprises a hydrocarbon liquid.
