This is the fifth article in a series covering water management in hydraulic fracturing in unconventional resources. The focus of this article is biological control. Additives to improve fracturing conditions can have negative effects on water treatment.

This is the fourth article of a series covering water management in hydraulic fracturing (HF) in unconventional resources. This article discusses the use of mechanical vapor compression (MVC) as a desalination technology.

Decommissioning costs are often made higher by decisions made during the initial engineering and construction stages of an offshore oil or gas field. Designing with a critical eye can go a long way toward reducing the decommissioning costs, which occur decades later.

You may not think that poetry and engineering have anything in common, but there is something poetic about the right design that elegantly solves a problem. And, there is undeniably something poetic in making the same mistake again.

Papers in this month's issue cover the API standard for subsea equipment, produced water challenges in mature fields, hydrate formation, and liquid-loading in aging gas developments.

The value of new technology, and its ROI, is examined. Understanding the value proposition is not a trivial matter. When investing in facilities technologies, we have traditionally looked to invest in those that will reduce Capex or Opex. But what about niche technologies?

Water condensation and/or hydrate formation at the top of pipelines are serious design/operation considerations in pipelines. This paper reports the results of tests conducted in a new experimental setup constructed for investigating gas-hydrate risks in varied operational scenarios.

Onshore gas developments are often characterized by drilling, fracturing, and production of wells before low-pressure gas-gathering systems are in place. As well production declines, liquid-loading issues begin to appear. Use of a twin-screw pump to boost deliquefication was investigated.

A relatively small concentration of a defoamer can have a significant impact on the dynamics of multiphase flow within a pipe, but the effect is generally temporary.

A growing number of alternatives for treating flowback water enable operators to meet the requirements for discharge or reuse of the water in the fracturing fluid, a scientist said recently.
