Oilfield chemistry
This paper presents a novel methodology for assessing the rapid mineral carbonation of carbon dioxide through geochemical interactions with carbon-, magnesium-, and iron-rich minerals abundant in geological formations.
This study contributes to enhancing the understanding of scale-inhibitor retention in rock formations.
This paper details formulation and characterization of a novel nanoparticle system composed of polyethyleneimine and dextran sulfate for direct lithium extraction from bulk oilfield brines in North America.

The growing amount of heavy crude processed worldwide has created additional separation challenges, leading some operators to turn to alternative technologies. In some cases, electrocoalescence has been an effective tool to separate oil from water. -
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.

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 wide range of corrosive elements and compounds from a variety of crudes has led to a renewed industry focus on corrosion and the effects it has on pipelines and vessels.
-
As producers push logistical and technological limits to operate in deeper water and more remote locations, maintaining and repairing offshore structures can present a number of challenges unique to these environments. One of the costliest is corrosion.
-
As the world's supply of crude becomes heavier, many of the world’s oil producers will have to think more carefully about heavy crudes and the challenges they pose for processing, storage, and transportation.

In an SPE webinar, “Foaming in Separators: Handling and Operation,” Wally Georgie, principal consultant at Maxoil Solutions, presented an overview of foam generation and how the design of processes and chemical management can exacerbate its detrimental effects in separators.

Issues associated with mercury’s presence in hydrocarbon processing systems have become more apparent as deeper and hotter reservoirs (often with higher levels of mercury) were exploited, and with the low-temperature gas processing used for liquefied natural gas (LNG) and natural gas liquids.
-
Semoga and Kaji fields experienced reservoir souring and suffered a history of calcium-carbonate (CaCO3) -scale cases before a proper scale-inhibition program was implemented. Problems with a free water knockout discovered continued scale issues, leading to investigation of the reasons.
-
The high level of dissolved iron commonly present in the Marcellus waters of Pennsylvania and West Virginia adversely affects the ability of scale inhibitor to inhibit calcium carbonate scale. This study tests two new products under a range of conditions.
