Ivanhoe Energy upgrades heavy oil bottoms

By OGJ editors
Houston, Mar. 16 -- Ivanhoe Energy Inc. has upgraded vacuum tower bottoms (VTBs) derived from heavy oil at its heavy-oil upgrading demonstration facility in California.

VTBs are the heaviest, most viscous component of crude oil, often less than 7º gravity. Canada's Athabasca bitumen typically contains 45-55% VTBs, with the rest lighter fractions of oil. California raw heavy crude contains about 33% VTBs, Ivanhoe said.

In the demonstration, Ivanhoe's heavy oil upgrading technology, operating in what the company calls its "high-yield" configuration, converted VTBs with viscosity of about 300,000 cp at 140º F. into a product of 1,300 cp at the same temperature.

After processing, the upgraded VTBs could be blended with lighter fractions separated by earlier processing to yield a product with viscosity low enough to flow in a pipeline without the need for diluent or heating, Ivanhoe said. It said the overall product blended yield from the demonstration run would exceed 90%.

In January, Ivanhoe ran whole California heavy crude through its 1,000 b/d demonstration facility in Belridge heavy oil field near Bakersfield (OGJ, Apr. 11, 2005, p. 24).

"The most recent run was a significant step forward in that the feedstock processed was dramatically heavier and more viscous (i.e. a solid rather than a liquid at room temperature) than the whole heavy crude run in January," Ivanhoe said. The recent test also was significant because it used a process configuration intended for specific commercial applications—those aimed mainly at viscosity reduction and maximizing liquid volume yields, the company said.

Next steps will be processing VTBs in a "high-quality" configuration and conducting extended runs. The high-quality configuration adds recycle operations and will be used where both high product quality and maximum byproduct energy are needed.

Ivanhoe said equipment additions and upgrades needed for the next steps will require 4-6 weeks.

It said data from the demonstration runs will enable it to start site-specific design and engineering for commercial 10,000-15,000 b/d plants.

Better Data, Better Analytics, Better Decisions

When Tue, Oct 27, 2015

The Oil & Gas industry has large amounts of data stored in multiple systems which are purpose built for certain tasks. However, good decisions require insights based upon the data in all of these systems. These systems in turn do not talk to each other. So the process of analyzing data, gaining insights, and making decisions is a slow one and often a flawed one. Good decisions require accurate analytics and accurate analytics require superior/sustainable data quality and governance. This webinar focuses on:

  • The importance of data quality and governance
  • How technological advances are making data quality and governance sustainable in order to get the accurate analytics to make solid decisions.

The Resilient Oilfield in the Internet of Things World

Tue, Sep 22, 2015

As we hear about the hype surrounding the Internet of Things, the oil and gas industry is questioning what is different than what is already being done. What is new?  Using sensors and connecting devices is nothing new to our mode of business and in many ways the industry exemplifies many principles of an industrial internet of things. How does the Internet of Things impact the oil and gas industry?

Prolific instrumentation and automation digitized the industry and has changed the approach to business models calling for a systems led approach.  Resilient Systems have the ability to adapt to changing circumstances while maintaining their central purpose.  A resilient system, such as Maximo, allows an asset intensive organization to leverage connected devices by merging real-time asset information with other critical asset information and using that information to create a more agile organization.  

Join this webcast, sponsored by IBM, to learn how about Internet of Things capabilities and resilient systems are impacting the landscape of the oil and gas industry.
