TITLE:                    INVESTIGATION OF LOST CIRCULATION MATERIALS IMPACT ON FRACTURE GRADIENT

ADVISOR:            Dr. Runar Nygaard

ABSTRACT: Lost circulation is a challenging problem to be prevented or mitigated during drilling. Lost circulation treatments are widely applied to mitigate losses using a corrective approach or to prevent losses using preventive approaches, also known as “wellbore strengthening”. The disagreement among the different wellbore strengthening theories and the lack of understanding the strengthening mechanism resulted in the absence of a standardized method to evaluate the effectiveness of LCM for wellbore strengthening application. An extensive experimental investigation was conducted using a new design high pressure LCM tester to investigate the effects of different parameters on the sealing efficiency of LCM treatments. In addition, hydraulic fracturing experiments, which simulates downhole conditions, were carried out to evaluate the impact of LCM addition on enhancing both; breakdown and re-opening pressure. The results showed that the sealing efficiency is highly dependent on the fracture width and the particle size distribution (PSD) of LCM treatments. A PSD selection criterion for LCM treatments was developed based on a statistical analysis of the experimental results. The addition of different LCM blends enhanced the breakdown and re-opening pressure up to 18% and 210%, respectively. The measured fracture widths under microscope were in the range of the D10 and D25 values of the used LCMs, which suggests the importance of PSD for wellbore strengthening application. Only one analytical model estimated realistic fracture widths when compared to the actual fractures, measured under the microscope.

Gates Foundation — grand challenges; health; innovation; Africa; biostatistics

Dear Colleagues:

The Bill & Melinda Gates Foundation is inviting applications that address specific challenges defined in the grant programs below. For details and application instructions, please visit the new Grand Challenges website. Please note that descriptions of the challenges are available on the website in Chinese, French, Portuguese and Spanish.

1) Grand Challenges Explorations is seeking innovative global health and development solutions and is now accepting proposals for its latest application round. Applicants can be at any experience level; in any discipline; and from any organization, including colleges and universities, government laboratories, research institutions, non-profit organizations, and for-profit companies. Initial grants will be US $100,000 each, and projects showing promise will have the opportunity to receive additional funding of up to US $1 million.

Proposals are being accepted online until November 11, 2015 for the following challenges:

2) New Interventions for Global Health: Vaccine Manufacturing. This challenge focuses on innovations in vaccine manufacturing platforms designed to lower production cost for vaccines that target diseases of great global burden and that are among the most costly to produce with current technologies.

Letters of Intent will be accepted until November 5, 2015. Read more about this grant opportunity here.

3) The Global Innovation Fund is accepting application on a rolling basis.  Please visit the website for more information http://globalinnovation.fund/apply-to-gif

4) An Interactive Biostatistics Course will be held from 16-20 November 2015 at the KwaZulu-Natal Research Institute for TB and HIV (K-RITH), based at the Nelson R. Mandela School of Medicine in Durban, South Africa. The primary goal of this course is to give participants an overview of the various biostatistical methods used in medical research so that they can both employ these techniques in their own research and better understand the results presented in medical literature. Lori Chibnik, PhD, MPH, a Biostatistician at Harvard University, will run an inspiring and hands-on training course on biostatistics where students will work with data from their own projects to understand basic statistical concepts and methods used in medical research. Travel Scholarships are available to allow trainees for across Africa to attend. For more information and to apply please visit www.k-rith.org. Deadline for applications:  1 October 2015.

5) In addition, the African Academy of Sciences and the New Partnership for African Development have launched Grand Challenges Africa in Nairobi, Kenya. This program joins others within the Grand Challenges family of grant programs supported by the Bill & Melinda Gates Foundation and its partners. Grand Challenges Africa will build on the global success of Grand Challenges programs in India, Brazil, and South Africa, as well as the strong base of Africa Grand Challenges grantees already funded by the Bill & Melinda Gates Foundation, Grand Challenges Canada, and USAID. Please read our latest blogs including one from the Global Health President. For more information please visit AAS.

Furthermore, as a forum for sharing ideas, pursuing new opportunities and keeping abreast of new developments in the field of global health, The Gates Foundation together with Grand Challenges Canada has set-up a LinkedIn group. All you need to join is a free LinkedIn account – go to Global Health Innovations and click “Join”

We look forward to receiving innovative ideas from around the world and from all disciplines. If you have a great idea, please apply. If you know someone else who may have a great idea, please forward this message.

Thank you for your commitment to solving the world’s greatest health and development challenges.

The Grand Challenges Team
