## Optimum Feed Tray Location in an NGL Fractionation Column

This tip of the month (TOTM) will demonstrate how to determine the optimum location of a feed tray in an NGL fractionation or distillation column by a short-cut method and the rigorous method using a process simulator. As an example, we will consider sizing a deethanizer by performing material and energy balances, distillation column short-cut calculations and rigorous tray-by-tray calculations. Finally, the TOTM will determine the optimum feed tray location by the short-cut and rigorous methods.

## Ideal Water Content Correlation for Sweet Natural Gas

In this TOTM, we will evaluate pressure and temperature applicability ranges and accuracy of the ideal water content correlation for sweet natural gases. In addition, the performance of the ideal water content correlations will be compared with the equation of state-based rigorous calculation methods.

## How Does Horizontal Well Planning Differ from Other Directional Wells?

In this Tip of the Month (TOTM) you will learn about the steps of horizontal well planning including determining target constraints, build rate, tangent section and more.

## Optimizing Performance of Refrigeration System with Flash Tank Economizer

Continuing the January 2008 Tip of The Month (TOTM), this tip demonstrates two methods to optimize the performance of a refrigeration system employing a flash tank economizer and two stages of compression. Specifically, we will minimize the compressor total power and condenser duty by optimizing the interstage pressure.

## Correlations for Vapor Pressure of Crude Oil Measured by Expansion Method (VPCRX)

This Tip of The Month (TOTM) will present simple correlations for determination of TVP and RVPE (Reid Vapor Pressure Equivalent) as described by ASTM Standard D6377 at a specified temperature.

## What You Should Know as a New Petroleum Employee About Wildcat Wells and Exploration

As a new member of the petroleum industry, there are a few things you should know about wildcat wells and exploration. This Tip of the Month (TOTM) explains why wildcat wells are an essential part of the exploration process and how the current environment of the industry effects exploration and wildcat efforts.
