Nouryon has introduced a range of demulsifiers that provide oil producers with a more sustainable option to separate crude oil from natural gas and water. The Witbreak NEO range is inherently biodegradable in seawater and has a better cost-to-performance ratio compared to conventional demulsifiers currently available on the market.
“High performing demulsifiers that also fulfill the strict environmental regulations outlined by the Convention for the Protection of Marine Environment of the North-East Atlantic (OSPAR) are still scarce,” said Mohammad Siddiqui, Global Technical Marketing Manager at Nouryon. “The Witbreak NEO range is an outcome of a collaborative innovation project with key customers and addresses the need for versatile demulsifiers that have a better ecological and performance profile, and they are OSPAR compliant as well.”
Nouryon supplies a full range of specialty chemicals to the upstream oil and gas production process. AB Ghosh, Managing Director Surface Chemistry at Nouryon, added: “We take great pride in the value of our product portfolio and we are committed to satisfy evolving demands in the oil and gas market. We look forward to rolling out the Witbreak NEO range and helping our customers set the standard for performance, both in application and environmental impact.”
Nouryon recently announced a €12-million investment that would double capacity at its surfactants plant in Stenungsund, Sweden to support the growth of several existing products as well as new more sustainable products for key markets including oil and gas, lubricants and fuels and asphalt.
BP Oman Achieves Significant Reduction in CO2 Emissions for the Khazzan Project
Fit-for-basin well cleanup solution enables zero-flaring delivery of new wells to central production facility
GHG emissions reduction goal
As part of BP’s commitment to advancing a low carbon future, BP operations around the world are striving to make a meaningful contribution to reduce GHG emissions. For BP Oman, a major GHG-emitting activity is associated with flaring in cleanup operations for new wells. For this scenario, BP Oman is taking the lead to identify and implement proactive ways of reducing GHG emissions in Khazzan Field for new well cleanups.
Introducing green completions
Supergiant Khazzan Field is characterized by tight reservoirs that require hydraulic fracturing to release the gas. After fracturing, wells are tested and cleaned up by the conventional method of flaring and burning the well fluids, which are gas and produced condensate. This results in the release of GHG to the atmosphere. To eliminate these emissions, BP Oman introduced green completions to Khazzan Field. The green completions technique redefines well testing from a GHG-producing activity to one that prevents GHG emissions by routing the hydrocarbons to the production facility.
BP’s ambition is to be a net zero company by 2050 or sooner and to help the world get to net zero. Schlumberger shares BP’s commitment to low carbon and is committed to set a science-based target by 2021 and update the CO2 emissions footprint ambition accordingly.
Collaborative design for challenging conditions
BP Oman engaged with Schlumberger to develop a fit-for-basin solution to clean up and produce gas from Khazzan Field after fracturing. All modifications and designs were performed through the Schlumberger RapidResponse customer-driven product development process to enable solids-free produced hydrocarbons at optimal conditions for combination with the processing facility pipeline.

Project success contributes to low carbon goals
The residual solids from stimulation operations that are often present in the fluid flowstream pose a risk to system integrity and can compromise process lines and production facility equipment. To address this risk, Schlumberger designed and installed an integrated separation, filtration, and acoustic monitoring system for the well testing solution.
One challenge was the relatively high separating process pressure needed, which demanded a specific well test design that didn’t exceed the process facility gathering system design pressure. A solution was developed by combining large-bore temporary pipelines and manifolds with a digitally enabled, high-capacity four-phase horizontal separator equipped with autonomous meters providing real-time measurements and monitoring efficient separation of the well effluent phases to deliver hydrocarbons at export specifications.
The design also enhanced process safety by incorporating 6-in safety valves in the electronic emergency shutdown system to address the high volume of hydrocarbons in the pipelines.
Project success contributes to low carbon goals
Schlumberger well testing solutions continue to operate at Khazzan Field and have set a new bar for operational efficiency and service delivery by improving customer performance. In 2019, the green completions well cleanup technique has been applied to 10 wells for flowback to clean up for production and reservoir testing. The result is more than 80,000 t of CO2 emission reduction. This is equivalent to taking nearly 18,000 cars off the road for a year.
