Water Desalination Applications in Shale-Gas and Polymer EOR Produced Waters
Oil and gas extraction using water has opened up new hydrocarbon resources. However they can produce four times more salty water byproduct than oil. Desalination in shale gas and polymer-flood EOR remain niche markets for lowering cost and improving production.
Aker Solutions and FSubsea Aim for Increased Oil Recovery With FASTSubsea
Aker Solutions and FSubsea have agreed to a joint venture, named FASTSubsea, to help operators increase oil recovery.
Case History of Dehydration-Technology Improvement for HCPF Production in the Daqing Oil Field
High-concentration polymer flooding can improve oil-displacement efficiency but separation of oil/water mixture becomes more difficult because of emulsification. In this work, a case history of dehydration technology for HCPF production and lab investigation of emulsion behaviors are reviewed.
Carbon Capture and Storage for Enhanced Oil Recovery: Integration and Optimization of a Post-Combustion CO2-Capture Facility at a Power Plant in Abu Dhabi
The authors discuss the results of a pilot project to capture post-combustion CO2 for purposes of EOR.
Water Management for Enhanced Oil Recovery Projects
Produced water from chemical floods can cause problems for separation and water treatment equipment due to the polymers and surfactants used. Challenges are greater offshore where space limitations can affect treatment options.
Low-Cost Technologies Can Boost Incremental Production of Mature Fields
A variety of low-cost technologies can result in an increase in production in mature oil and gas fields, although the increase is usually temporary and not always economical.
New Water-Treatment Technologies Tackle Offshore Produced-Water Challenges in EOR
Enhanced oil recovery processes, particularly offshore, create challenges for produced water treatment. This option reviews technology options and current applications.
The Lowdown on Low-Sal Water Technology
Changing the salinity of injection water could make the difference in getting more out of existing wells.
How Does Low-Sal Water Work?
Using low-sal water for flood can add 30% to the amount of oil that can be recovered from a reservoir. What is the theory behind it?
Processing of Sour Natural Gas Reaches New Highs
ExxonMobil is testing its Controlled Freeze Zone technology, a single-step cryogenic process that allows carbon dioxide (CO2) to freeze in a controlled method and then melts the CO2. After recovery of the methane, the CO2 can be sequestered or used for EOR.
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.
Global Workshop Series Addresses Water Handling Issues
Water handling is becoming increasingly important as a technical and economic tool for improved oil recovery and enhanced oil recovery (EOR) projects. A global series of workshops to address these issues has been planned.
