Accurate measurement and prediction of crude oil and natural gas liquid (NGL) products vapor pressure are important for safe storage and transportation, custody transfer, minimizing vaporization losses and environmental protection. Vapor pressure specifications are typically stated in Reid Vapor Pressure (RVP) or/and True Vapor Pressure (TVP). In addition to the standard procedures for their measurements, there are rigorous and shortcut methods for their estimation and conversion. [Keep reading]
Previously, we've discussed the hydrate phase behavior of sour natural gas mixtures. Specifically, we looked at carbon dioxide inhibits the hydrate formation slightly while hydrogen sulfide enhances hydrate formation considerably. This Tip of the Month (TOTM) will extend the previous study on the natural gas hydrate formation phase behavior. Specifically, it will study the impact of nitrogen on the formation of hydrate in a natural gas mixture. [Keep reading]
Seismic velocities derived from moveout velocity analysis can be used to interpolate between wells or may be the only velocity information available in a new basin. This white paper will explore how we use the results from the velocity analyses, make corrections for lag, and account for floating datum. [Keep reading]
In the post-World war II period, the steels used in the oil and gas industry were quite different from what we use today. This tip of the month (TOTM) presents a brief overview of improvements in the steels used in oil and gas processing equipment for safer and more reliable operations. [Keep reading]
There are different process configurations for adsorption dehydration systems. The most common arrangements are two-tower and three-tower configurations. In past articles, we have discussed the efficient operation of molecular sieve dehydration units. Specifically, the benefits of standby time in the adsorption dehydration processes and impact of feed gas conditions. This month’s Tip of the Month compares the required size of major equipment for the two-tower system with the three-tower system, considering a number of key parameters. [Keep reading]
