Oilfield chemistry
This paper describes a case history in the UAE in which the cleanout of scale contaminated with naturally occurring radioactive material was conducted successfully.
This study leverages oil-fingerprinting technology and geochemical data to evaluate the fluid connectivity between a main field and its stepout wells.
This paper provides details of a pilot study conducted on multiple wells, showcasing the potential of a novel biotechnology in Bakken enhanced oil recovery.

Approaches to integrated investigative testing and root cause identification are discussed to prevent solid emulsions from stabilizing to impair flowlines and other field infrastructure. -
Polymer gel is frequently used for conformance control in fractured reservoirs, where it is injected to reside in fractures or high-permeability streaks to reduce conductivity. This paper discusses the behavior and blocking capacity of gel during chase waterflooding.

This paper focuses on a numerical-modeling analysis of the acid-gas-injection (AGI) scenario in carbonate HP/HT reservoirs, and presents the way in which AGI impacts asphaltene-precipitation behavior.
-
In the past decade, analytics in the oil field has grown to be a major discipline, integrally supporting the application of many different types of production chemicals and becoming viewed by some as a technology differentiator.

For nearly a decade, Saudi Aramco has been studying how altering the chemical makeup of seawater injected into its reservoirs can increase production. The result is "smart water" that can boost the sweep effectiveness of a waterflood.
-
This paper presents a state-of-the-art review of scale-inhibitor-analysis techniques and describes how these techniques can be used to provide cost-effective scale management.
-
This paper describes a novel method of chemical dosage based on time-resolved fluorescence (TRF) that allows a simple, accurate, and efficient quantification of chemicals below parts-per-million ranges, even for double (scale/scale, scale/corrosion) quantification.
-
The deep-ocean Raman in-situ-spectrometer (DORISS) instruments were developed for the purposes of identifying compounds and studying in-situ chemical reactions in a nondestructive manner while working with solids, liquids, and gases.

Part of what makes DME an intriguing EOR technology is that it is soluble in both water and oil—with a preference for the latter. Shell’s plan is to add DME to the waterflooding stream to reach a concentration of about 16%, the upper limit of its dissolvability.
