Correlations for Conversion between True and Reid Vapor Pressures (TVP and RVP)
February 4, 2016
|
Tip of the Month
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 ad...

What is the impact of Nitrogen on the Natural Gas Hydrate Formation Conditions?
January 20, 2016
|
Tip of the Month
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. Specif...

How Do We Use the Results from Velocity Analysis in our Seismic Data?
January 6, 2016
|
Tip of the Month
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.

Improvements in the Steels Used in Oil and Gas Processing Equipment over the Last Half Century
December 7, 2015
|
Tip of the Month
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.

Adsorption Dehydration: Two-Tower vs. Three-Tower System
November 9, 2015
|
Tip of the Month
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 ...

What is the Impact of Feed Gas Conditions on the Adsorption Dehydration System?
October 5, 2015
|
Tip of the Month
Adsorption dehydration units can reduce the water content of a gas stream to less than 0.1 ppmv. The gas industry normally uses adsorption dehydration units upstream of a liquefied natural gas (LNG) plant or a deep natural gas liquid (NGL) extraction plant where the gas temperature reduces to less than -160 °C (-256 °F) and -100 °C (-148 °F), respe...
