Natural Gas Compressor Lubrication
by David Doyle, CLS, OMA 1 & 2
Vice President & Operations Manager
Recovery and processing natural gas streams in developing energy reserves places significant demands on the performance of natural gas compressors. One of the key players in compressor reliability is the performance of the compressor’s lubricant. Various factors affect the lubricant’s performance, including product formulation, equipment design, and the makeup of the natural gas composition. Understanding the general requirements and problems associated with the lubrication of natural gas compressors, as well as routine testing of the lubricant, can greatly benefit the performance life of a compressor in a natural gas stream.
Compressor design can influence lubrication performance. Reciprocating compressors are used where high pressures are required. Because there is a higher tendency for oil and gas mixing in reciprocating compressor design, higher viscosity mineral oils or synthetic polyglycol-based lubricants are sometimes used due to their low hydrocarbon solubility.

Oil Sampling Guidelines
by David Doyle, CLS, OMA 1 & 2
Vice President & Operations Manager
There are a variety of manners in which an in-service oil sample can be obtained. Many times, choices are based on the availability of access points. Sampling can often be made easier and expedited with improved safety by installing sampling ports in strategic locations. Some equipment manufacturers provide factory installed sampling ports.
The best sampling point may not always be the most practical. In this case, the most important factor when considering a sampling location is consistency, which greatly affects the quality of the historical data in trending analysis. Below are sampling practices that may be employed for some common systems. More . . . . .
