Abstract:
Mud logging provides important data to the exploratory drilling industry, traditionally this data is provided by an isothermal GC method, and while the results were reliable and helped to correlate understanding of depth and content, the method was slow. An improved method using a rapid heating technology to temperature program the analytical column can achieve significantly quicker analysis, and much improved separation of sample constituents. This technology greatly reduces the heating/cooling cycle time, while also providing much higher resolution.
This Valco developed technique uses cold on-column injection, with an extremely accurate and fast heating technology with a unique temperature measurement/application method. This technology greatly reduces not only the heating and cooling times, but also the size and power required for instruments doing this analysis.
This temperature control technology is not limited to columns, but can be applied to injectors, transfer lines, and other components as required. The application of this technology can provide higher throughput and higher resolution well beyond the capability of traditional GC techniques. The total cycle time for this enhanced C1 to C5 analysis with seven components is less than 20 seconds with a total recycle time less than 45 seconds. In this presentation we will describe the details of this technology, its configuration, and our test results.
