Dr. Hays and Students Place First in the American Radio Relay League RTTY Rookie Roundup

Aerospace engineering sophomore Jarrod Manning, data science masters student Jorge Garcia, and Dr. Hays placed first in ARRL’s (American Radio Relay League) RTTY rookie roundup competition on August 18th.

The students used the national weather center’s tri-band yagi antenna to make 50 contacts using RTTY (Baudot FSK digital mode). Contacts came from widely varying distances as close as Norman, and as far abroad as Belgium. The competition encourages new amateur radio operators that have earned their license within the previous three years to engage in antenna, propagation, and digital mode studies. ARRL is the primary amateur radio organization in the United States and sponsors many similar competitions throughout the year.

Chinedum Ezeakacha presents over Performance Verification and Material Testing of Liner Hanger Sealing Components for Oil and Gas Application

On Friday, February 8, AME hosted a seminar from Chinedum Peter Ezeakacha, a post-doctoral research associate at the Well Construction Technology center at OU. In his research, he speaks about performance verification and material testing of liner hanger sealing components for oil and gas application.

Abstract: Drilling operations, particularly in an offshore environment, require special tools and equipment. Liners and liner hangers are commonly used in offshore drilling applications instead of full string casings. When a well section is drilled, liner hanger and cement are used to engage and seal off the liner, connecting it to the previous casing. Typically, the liner hanger seal assembly is placed up-stream to the cement column. This arrangement prevents the independent evaluation of the integrity of both mechanical barriers (cement and liner hanger seal) after installation. The report from an oil and gas regulatory agency highlighted that the cause of a recent underground kick with this type of arrangement can be linked to the failure of he mechanical barriers under the operating conditions. While some of the design criteria for liner hangers are obtained from API 17D (Design and Operation of Subsea Production Systems – Subsea Wellhead and Tree Equipment), there is currently no standard that specifically addresses liner hangers or seals, nor how to test them. In this seminar, the performance of cement sheath and elastomeric seals used in liner hangers will be presented. Different downhole conditions in which these mechanical barriers can fail were simulated. The scope of the project necessitated a cross-disciplinary investigation involving the knowledges from mechanical engineering, petroleum engineering, and civil/material engineering. Thus, the barrier testing protocols were developed in consonance with the key questions raised by the agency, existing practice in 30 CFR 250.425, as well as ASTM and ASME standards. The summary of the findings in this study points towards testing the mechanical barriers for the anticipated downhole conditions before deploying them, particularly in gas-migration prone zones. In this study, the term “barrier(s)” defines the use of cement sheath and the liner hanger sealing assembly to prevent uncontrolled influx and migration of formation fluid to a shallow formation or surface facilities.

Wind Tunnel Design Team Takes 2nd Place at AIAA Student Conference

AME’s student wind tunnel design team recently accepted an award in Albuquerque, New Mexico, on the weekend of April 13th at the student conference of the American Institute of Aeronautics and Astronautics (AIAA). Representing the team, Karen Martinez Soto traveled to the conference to accept the 2nd place award on behalf of her team for the AIAA region IV team technical paper category. In addition to Soto, her teammates include Samuel Jett, Orhan Roksa, and Marko Mestrovic, who are all undergraduate students at AME.                                         Their paper highlights the design, fabrication, and uniformity testing of a low-budget, wind tunnel. With a budget of only $5,000, their group examined characteristics of wind tunnels through computer models and they continued their study further by building a tunnel of their own to test other aerodynamic components. The focus of their design and construction for this tunnel, according to their paper, serves to provide “a robust platform for development and testing of many aerodynamics components, including UAV propellers.” Congratulations to Karen, Samuel, Orhan, and Marko for their impressive efforts to design and test a wind tunnel and their 2nd place award from the AIAA student conference.
