Preventing Emulsions by Mitigating Solids
Approaches to integrated investigative testing and root cause identification are discussed to prevent solid emulsions from stabilizing to impair flowlines and other field infrastructure.
Positron-Emission Tomography Offers New Insight Into Wormhole Formation
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.
Scaling Up Smart Water
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.
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.
The Importance of Scale-Inhibitor Analysis—A State-of-the-Art Overview
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.
Time-Resolved Fluorescence for Real-Time Monitoring of Scale and Corrosion Inhibitors
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.
Deep-Sea Laser Raman—Developments for In-Situ Chemical Analysis and Applications
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.
A New EOR Concept From Shell To Enhance Waterflooding
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.
Biocide Treatment Program Reduces Premature Coiled Tubing Failures
A study done to find the root cause of coiled tubing string failures in Montney indicated microbial-induced corrosion, leading the CT service provider to create a biocide treatment program.
Chemical Sand Consolidation: Developing a Strategic Capability Across a Wide Portfolio
Chemical sand consolidation works by pumping chemicals downhole to strengthen the formation and stop sanding. In most cases reported in the industry, chemical consolidation has been used in short production intervals (less than 100 m).
Balancing Artificial Lift, Chemical Injection To Achieve Production Goals Over Life of Well
Production engineers are often asked to manage both the artificial lift (AL) system and the upstream chemical injection program for a project.
