Apache Corporation Donates $2 Million for Petroleum Research

Texas Tech and Apache Corp. have announced a $2 million gift to the Whitacre College of Engineering that will establish the Apache Upstream Research Center in the new Petroleum Engineering Research Building.

This center will be an important aspect of the new Petroleum Engineering Research Building's laboratories, focused on the latest environmentally responsible fracturing techniques including horizontal well drilling, rock mechanics, the energy-water nexus, wellbore integrity, and well cementing. Research will be conducted in the center by faculty members from multiple engineering disciplines and will advance the leading edge of fracturing procedures and environmentally responsible practices.

In addition, both undergraduate and graduate students will have the opportunity to apply new knowledge and innovations to their engineering studies as these advancements are discovered. This will build upon the robust theoretical and practical education that Texas Tech engineers receive.

Apache's gift is eligible for an additional $2 million of matching funds from the Texas Research Incentive Program, created by the state of Texas. Once matching funds are received, the funding will support equipment purchases and research projects in the fracturing techniques center.

ASME Students Win Second in International Old Guard Contest

Texas Tech won second place in the Old Guard Oral Presentation Contest at the ASME 2012 International Mechanical Engineering Congress & Exposition. The contest included representatives from England, France, India, Lebanon, Mexico, the United States, and other countries.

The project was "Reinventing the Wheel: A Radially Collapsing Wheel for an Innovative Wheelchair Design." The design for the radially collapsing wheel targets the demand by users for a size-conscious wheel that does not need to be removed from a wheelchair for transportation. This design meets all structural strength requirements and adds the revolutionary benefit of collapsibility. The wheel design uses a scissor geometry supported by 16 structural spokes. Each spoke is connected to one of two central hubs, with adjacent spokes alternating between hubs. When fully extended, the hubs separate to provide further stability and support for the wheel. Rubber tread completes the smooth radius. Additionally, the tread provides shock absorption and vibration reduction, which will greatly increase the user's comfort. To collapse, the hubs easily slide into plane and allow the scissor geometry to fold about the central axis. After collapsing, the assembly slides neatly into the cylindrical housing located under the seat of the wheelchair. This collapsed wheel provides a compact and streamlined package that gives this wheelchair an advantage over all other foldable chairs.

The team previously won first place in the Old Guard Oral Presentations at the regional District E competition of ASME's Student Professional Development Conference. The winning student presenter was Pejmon Arbrapour.

Mechanical Engineering Research Published in PNAS

Mechanical engineering graduate students Cheng Ji and Archis Marathe, and faculty members Drs. Jharna Chaudhuri and Yanzhang Ma's groundbreaking research on boron nitride is featured in the latest issue of the Proceedings of the National Academy of Sciences (PNAS).

Boron nitride is normally a soft material that can be used as a lubricant, as well as other applications in industry. After undergoing special processes at ultra-high pressures and temperatures, boron nitride can transform to two different super-hard forms: cubic boron nitride and wurtzitic boron nitride. These materials have broad applications in areas such as tools for fabrication of extremely hard materials or armor for military forces.

In the published work, the group reported successful transformation of the soft boron nitride, with a high degree of disorder, to wurtzitic boron nitride by way of plastic shear under high pressure, and provided a mechanism for such transformation. The discovery established an alternative path to the synthesis of this super-hard boron nitride under a record low pressure and room temperature, leading to a new way for mass production. This reveals a new mechanism for material synthesis of this type. It also proves the concept that structures that can only be obtained at high pressures, but revert after unloading, can be trapped through the application of shear.

Modified Zipper Frac
Modified Zipper Frac

Researchers Develop Improved Fracturing Techniques

Dr. Mohamed Soliman; chair of the Bob L. Herd Department of Petroleum Engineering, George P. Livermore Chair in Petroleum Engineering, and professor of petroleum engineering; and two graduate students in petroleum engineering, Mehdi Rafiee and Elias Pirayesh; have developed new techniques to enhance the process of hydraulic fracturing.

In recent years, new fracturing techniques have sought to enhance production of trapped hydrocarbons. Zipper frac, for example, is one of those techniques, which involves simultaneous stimulation of two parallel horizontal wells. In this proecess, fractures in each stage propagate toward each other, so the induced stresses at the tips force fractures further and increase output. The group's new patent pending design is a modified zipper frac (MZF), where fractures are initiated in a staggered pattern to induce stress, not only at the tips, but also in the middle area between fractures.

A second patent has been filed to cover an optimization technique that maximizes production through variable spacing between hydraulic fractures. Fractures are not spread equally; instead, measurements are taken after the first fracture to determine placement of subsequent fractures.
