Transportation of Natural Gas in Dense Phase – Nord Stream 1
March 30, 2022
|
Tip of the Month
Pipelines have been built to transport CO2 and natural gas in the dense phase region due to its higher
density which results in a smaller pipeline diameter resulting in significant capital cost savings. Dense phase
transport also provides the added benefit of no liquid formation in the pipeline for produced natural gas
gathering systems.
The applic...

Overview of Gas Lift; Part 3: Operational Field Procedure for Identifying, Selecting, and Optimizing a Gas Lift Well
March 1, 2022
|
Tip of the Month
Part 3 of the Overview of Gas Lift series has procedures for identifying, selecting, and optimizing technical as
well as field operations for a gas lift well.
Section IIIA reviews the gas lift well candidate related to gas content in the reservoir fluid and a choice of gas lift
or pumping.
Section IIIB discusses the well completion related to dim...

Tip of the Month
In the Part 1 of this Series on Gas Lift History and Basic Well Parameters, an attempt was made
to bring into focus the primary “state of affairs” of Gas Lift operations in the USA.
Part 2 will discuss basic Gas Lift well casing and tubing components, and their operational
function, as well as Choke Flow relationships in Gas Lift wells.
In the Firs...

Estimation of Surface Tension of Hydrocarbon Liquids in Equilibrium with Natural Gas Mixtures
January 6, 2022
|
Tip of the Month
In December 2021 tip of the month (TOTM), we presented two simple empirical correlations for estimating pure liquids surface tensions of the paraffins methane through n-octane. The two correlations express the surface tension as a function of the reduced temperature and molecular weight with only two (first correlation) and four (second correlation...

Estimation of Surface Tension of Pure Paraffin (Alkane) Hydrocarbons
December 7, 2021
|
Tip of the Month
Two simple empirical correlations and a corresponding states method reported in the literature are used to estimate pure liquids surface tensions for the paraffins methane through n-octane. The two correlations express the surface tension as a function of the reduced temperature and molecular weight with only two (first correlation) and four (secon...
