Use of Preservation Chemicals Following Hydrostatic Testing of Pipelines
This paper considers some of the challenges and learnings associated with the application of chemicals for preservation of coated pipe/flowline for a major liquefied-natural-gas (LNG) project in Australia.
The Importance of Inhibitor Analysis in Scale Management—An Overview
The accurate and precise analysis of scale inhibitors—in conjunction with other field data such as ion analysis, total suspended solids, and productivity index—plays an important role in making decisions about the efficiency of scale squeeze and continuous chemical injection treatments.
Implementation of a Metric-Driven, Statistical Chemical Management Program for Unconventional Plays
The challenges for operators in the Eagle Ford have been enormous, which can push chemical management to the back burner. But there is a price to be paid down the road. Operators have recently become more mindful of implementing metric-driven chemical management programs.
Electrocoalescence: An Alternative Technology for Separating Emulsions
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.
Water Management for Hydraulic Fracturing in Unconventional Resources - Part 5
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.
Defoamer Improves Flow, But Effect Is Temporary
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.
Corrosion Monitoring and Mitigation Technologies
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.
The Challenges of Processing and Transporting Heavy Crude
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.
Webinar Highlights Effects of Foam in Separators
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.
Advancements in the Removal of Mercury From Crude Oil
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.
Case Study—Calcium-Carbonate-Scale Inhibitor Performance Degradation Because of H2S-Scavenger Injection in Semoga Field
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.
Evaluation of Scale Inhibitors in Marcellus High-Iron Waters
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.
Challenges of Water Treating for Chemical Enhanced Oil Recovery
Higher oil prices has created increased interest in chemical enhanced oil recovery (CEOR) using polymers, surfactants, and alkalis. This technology poses some special challenges, especially around water treatment.
Acrolein Provides Benefits and Solutions to Offshore Oilfield-Production Problems
Offshore production systems can be impacted negatively by numerous problems attributed to bacterial activity, associated hydrogen sulfide and biogenic iron sulfides, and mercaptan production. Acrolein provides a distinctive all-in-one chemical solution to assist in resolving these problems.
