Abstract: Described herein are methods and systems, and techniques relating to hydrocarbon-bearing formation testing and, particularly, to estimating a formation condition. The disclosed methods, systems, and techniques allow for improved prediction of the formation condition and cleanout of the formation following well drilling. In some cases, the disclosed methods, systems, and techniques include using a formation testing tool to obtain a sampled fluid from a formation according to a set of sampling parameters and using the formation testing tool to analyze the sampled fluid to identify a set of fluid parameters for the sampled fluid. A numerical model may be used to determine a formation condition with inputs including the sampling parameters and the fluid parameters.

Abstract: A system and method for controlling flow of air into an air compressor of an air compressor system includes a proportional solenoid valve configured to control flow of supply air into the air compressor in proportional response to sensed air pressure generated by the air compressor system.
