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.

TED Talk on methane and the oil and gas industry 0

This TED Talk heralds a new era in fighting climate change, from space

Watch this video to learn about a bold, new initiative to combat global warming

EDF and partners are launching a rocket to put a new satellite in orbit that could change the course of global warming in our lifetimes.

MethaneSAT will gather data about a pollutant – methane – that’s warming the planet, and put that data in the hands of people who can easily fix the problem.

EDF President Fred Krupp unveiled the groundbreaking project at TED’s flagship event in Vancouver, British Columbia, as part of The Audacious Project, successor to the TED Prize.

Just the first step will have the same near-term climate benefit as shutting down one-third of the world’s coal-fired power plants.

Our goal is to cut methane emissions 45 percent by 2025, and the data gathered by this satellite will make that possible. Nothing else will have the same kind of near-term impact at such a low cost.

The power of information

To learn the magnitude of the problem with methane, we collected data with drones, planes, helicopters, even Google Street View cars. It turned out that emissions are up to five times higher than what the government is reporting.

So we didn’t wait for Washington. We published our research, shared it with everyone and saw them take action. Leading oil and gas companies replaced valves and tightened loose-fitting pipes. Colorado became the first state to limit methane pollution. California followed suit, and the public joined in.

By bringing the right people to the table – and leveraging the best of technology, science, data and partnerships – we were able to make the invisible visible, empowering everyone. This enabled us to find new solutions that can be taken to scale and make a lasting impact.

And that’s what the emerging Fourth Wave of environmentalism is all about.
