Engineering

The Master of Science in Bioengineering program offers interdisciplinary education to engineers and scientists to apply engineering approaches on medicine and biological research questions. For developing careers in biomedical industry, the degree offers research opportunities in five core bioengineering fields, namely Biomechanics, Bioinstrumentation, Biomaterials, Bio-imaging, and Bio-computation. The Master of Engineering (MEng) degree program is an interdisciplinary, non-thesis program, offered on the campus of Texas Tech University and by distance. Due to its interdisciplinary nature, this program does not require specific major and minor subjects. However, the program does allow up to six hours of course work to be taken outside of engineering, upon the approval of the graduate advisor. The MEng degree program has three options: Standard, Healthcare Engineering, and Doctor of Jurisprudence (JD) & MEng program. The MEng degree standard option is designed for students to pursue an interdisciplinary study through taking engineering courses from any of the college's disciplines. Healthcare Engineering option is designed to meet the growing demand for engineers trained to apply the principles of engineering, health sciences, and business administration to effectively manage the physical, technological, and supports services of healthcare facilities in order to optimize the safety, quality, efficiency, accessibility, and cost effectiveness of healthcare delivery processes and healthcare systems. The JD and MEng program is designed for individuals interested in the areas of intellectual property (particularly patents), and law and Engineering.

Issues such as fluid flow at periphery of the Darcy equation, well placement and spacing and reservoir heterogeneity indicators are studied. The Fracturing and Production lab evaluates hydraulic fracturing technology, such as fracturing shale formations, wellbore/cement integrity and production operations of all types. Other labs for PVT, petrophysics and enhanced oil recovery (EOR) studies are also contained in the new building. Current focus is to develop an EOR database. We are making an effort to establish a consortium to enhance shale oil and gas development. In addition we are in the process of building a facility around the deep, large diameter test well located on our East Campus which is roughly 10 miles from the main campus. Large scale research such as artificial lift, flow assurance, cementing and field facilities control and optimization will be implemented at the East Campus. With our legacy of production optimization, the department sponsors the annual Southwestern Petroleum Short Course in which industry schools are developed and presented and the technical program presents papers on various Petroleum technical subjects which are then cataloged in annual proceedings.
