Chemical and Petroleum Engineering

Chemical engineering has grown out of a combination of chemistry and engineering associated with industrial processes. Today, it comprises knowledge used in processes that change the physical state or composition of materials. Chemical engineers hold key roles in the design, development, production, and purification of materials considered essential to human life and well-being, such as food products, fuels and lubricants, pharmaceuticals, fertilizers, synthetic fibers, microelectronic components, and plastics. Chemical engineers are involved in reducing the use of energy to make products in a safe and sustainable way and minimizing environmental impacts. Areas of study in the Chemical Engineering Department include (but are not limited to):

Reaction Kinetics, Environmentally Beneficial Catalysis, Fuel Cells, Biofuels, Interfacial Phenomena, Biotherapeutics, Regenerative Micro-Tissue Engineering, Exploiting Supercritical and Gas-Expanded Liquids in Crystallization and Benign Chemicals Processing, Hydrothermal Liquefaction, Electrocatalysis, and Photoelectrocatalysis. 

Petroleum engineering is concerned with the drilling, recovery, production, and distribution of petroleum and natural gas. Petroleum engineers use knowledge of fluid and rock properties in subsurface environments to produce oil and gas safely and economically. At the University of Kansas, the focus is on reservoir engineering and improving production from oil and gas reservoirs. Reservoir engineers use geological detection with computerized mathematical analysis to produce raw materials. Through such techniques, petroleum engineers continue to extract oil and gas from reservoirs considered uneconomical only a few years ago. Petroleum engineering is uniquely challenging in that the raw material must be recovered far from direct observation. Areas of study in the Petroleum Engineering Department include (but are not limited to):

Hydraulic fracturing and acidizing of unconventional reservoirs, Characterization and simulation of tight oil and gas reservoirs, Oilfield nanoparticles, CO2 enhanced oil recovery and CO2 storage, Phase behavior of reservoir fluids, Shale gas reservoir development, Anti-scaling and anti-waxing in oilfield, Kinetics of crude oil combustion, Polymer flooding, and Polymer Gels. 

Ph.D. Admission Requirements

To qualify for study in any of the graduate programs in the Department of Chemical & Petroleum Engineering a student generally must have earned an accredited bachelor's degree and/or master's degree in chemical or petroleum engineering. However, a student with good preparation in another engineering discipline or a related field, such as physics, may qualify by taking the appropriate prerequisite undergraduate courses. These courses are determined on a case-by-case basis by the Department's Graduate Admissions Committee/Director.

Students admitted with baccalaureate degrees in chemical or petroleum engineering are usually able to enroll in the graduate core courses listed in our Graduate Program Manual. Students with degrees in other branches of engineering or in mathematics, chemistry, physics, or other sciences must take undergraduate courses to provide the necessary background for the graduate level courses and are admitted provisionally. See undergraduate prerequisite courses listed in the M.S. Degree Requirements section. Students who have already completed a M.S. degree will have the total number of hours reduced on a case-by-case basis, with the approval of the Graduate Standards Committee, and based on individual background and course history. No credits will transfer in at the graduate level; however, the 60 total credit hour requirement can be reduced to as low as 45 credit hours. 

All graduate applications must be submitted online.

Regular Status

For admission to regular status, the student must have an undergraduate grade point average of at least B (3.0 on a 4.0 scale). For students whose undergraduate GPA is below 3.0, admission on probational status will be considered on a case-by-case basis. Graduate Record Examination (GRE) scores are required.

Provisional Status

An applicant may be admitted as a provisional graduate student when either the quality or type of undergraduate preparation is deficient, i.e., the student's undergraduate grade-point average is below 3.0 on a 4.0 scale or the student has not met the prerequisite undergraduate courses to do graduate work in the department or program to which he or she has applied.

After completing the prerequisite courses as a provisional graduate student, the department reviews his or her performance and recommends that the student (1) be transferred to regular status, or (2) be dropped from the Graduate School.  

Important note for International students seeking admission: There are new restrictions related to international students who do not qualify for regular admission in either academic background, GPA, or English proficiency. A new policy passed by the US department of Homeland Security forbids US universities from issuing the I-20 and other travel documents for "provisional" or "conditional" students. For more information, see the July 2016 policy

Foreign Student English Proficiency

The following are the acceptable means of verifying English proficiency for purposes of admitting non-native speakers of English and/or international students to graduate studies. These guidelines also apply to U.S. citizens and permanent residents who are not native speakers of English; they are subject to change by official action of the appropriate governance bodies.

  1. Receipt of an official copy (not student's copy) of an applicant's English proficiency standardized test scores (e.g., TOEFL) achieved not more than two years prior to the semester of first enrollment.
  2. Graduation with a baccalaureate degree (or higher) earned in residence from an accredited English-medium U.S. college, university, or an institution of higher education or such an institution in the United Kingdom, Australia, New Zealand, Ireland, an English-speaking province of Canada, or an English-speaking Caribbean country, with instruction conducted in English. Degrees earned online may not be used to verify English proficiency.

All foreign students who are not native speakers of English must be screened by the Applied English Center on arrival, regardless of their TOEFL or other test scores, and according to the Rules and Regulations of the Faculty Senate, such students must enroll in the English courses specified for them by the Applied English Center.

Required Application Documents

Before an application is submitted for review, all supplemental documents must have been received by the Department. A list of the documents for both International and Domestic students are listed above.

The score requirements for the TOEFL, PTE, and IELTS-Academic exams can be found HERE.

Visit Us

Graduate program staff can assist prospective students in determining the fit between the student and the program. Staff can facilitate a campus visit. If you would like to schedule a visit,  there are two main options:

The first, and most preferred, entails simply applying for admission to the program. All prospective students are welcome to attend our Open House in early November and some highly qualified admitted students may be invited to participate in Visitation Days in late February or early March (prior to the fall semester of your intended matriculation). These organized visitation opportunities will allow you time to gather a great deal of first-hand information which we hope will help you in making a final decision about whether to attend KU.

The second option is making arrangements to visit us on your own, outside of organized events. With early notification, we will do our best to work with you to provide information and schedule appointments with faculty when possible. 

Contact Information

Please contact the CPE Graduate Program Assistant, cpegrad@ku.edu or (785) 864-2900, if you would like to  schedule a campus visit, or have questions about the program or the application process.

Ph.D. Degree Requirements

One of the goals of the department is to develop quality Ph.D. researchers who are well prepared for vocational and personal success. This policy sets forth a balanced program to develop and evaluate students in an efficient and fair manner. Equal consideration is given to the academic and the research ability,  as both areas are required for success in industry or academia. 

The Ph.D. graduate program typically consists of the completion of 60 credit hours beyond the B.S. degree or 45 credit hours beyond the M.S. degree. For more details about the courses and general timeline, see our Graduate Program Manual.

An advisory committee of 5 or more members is formed for each Ph.D. aspirant: at least 3 tenure / tenure track faculty from the department and 1 member from outside the department at KU are required. The student’s research advisor normally serves as the committee chair. See the Graduate Catalog for doctoral committee composition requirements. The committee works with the aspirant to develop a plan of study and monitors the progress of the student throughout the remainder of the Ph.D. program.

A plan of study must be approved by the student’s advisor, the examining advisory committee,  and the departmental Graduate Studies director by the end of the first semester. Before scheduling the comprehensive examination, the aspirant must satisfy residency, basic research skills, and the responsible scholarship requirements.

The research skill requirement provides the aspirant with a research skill distinct from, but strongly supportive of, the dissertation research. Work done to fulfill this requirement should involve study in an area complementary to the dissertation research and should enhance the student's ability to carry out the research. 

Preliminary Examination of Research - B.S. to Ph.D.

The Preliminary Examination of Research is administered to students requesting admission to the Ph.D. program without earning the M.S. degree. Successful completion of the preliminary examination admits the student into the Ph.D. program with aspirant status. Students taking this examination must have completed the graduate core courses at KU with the required GPA. The examination determines the student’s aptitudes for: (a) Independent, original, critical thinking; (b) Planning and organizing a research program; (c) Use of previous work and background literature to demonstrate understanding of the planned research within the scope of the larger project and ability to conduct that research; (d) Application of fundamental theory (e.g., equations) to the proposed work and; (e) Effective communication of technical work. The preliminary examination consists of a written report (5 pages maximum), oral presentation (15 minutes maximum), and questions by the examining committee (25 minutes maximum). The written and oral portions are prepared by the student only, with no review or editing by the research advisor or any other person. The written report is submitted to the committee one week before the oral examination. Questions are directed toward determining the 5 aptitudes listed above. A rubric for the oral and written portions will be provided to the student beforehand.

Comprehensive Examination

The Ph.D. aspirant takes the comprehensive examination after the completion of a majority of the course work for the Ph.D. and all department, school, and general requirements prerequisite to this examination, including residency, research skills, and responsible scholarship requirements. To prepare the aspirant for the comprehensive examination, the advisory committee may require enrollment in C&PE 902, Preparation for the Ph.D. Comprehensive Examination. The examination consists of 2 parts: a written proposal for research and an oral examination based on, but not limited to, the research proposal.

For the research proposal, the student is assigned a topic of current interest to the chemical and/or petroleum engineering profession. This assignment is made by an examining committee of at least 5 persons, at least 3 must be tenure / tenure track faculty from within the department including the advisor and at least 1 person from outside the department at KU. The aspirant identifies a research problem in the assigned topic area and prepares a written proposal for research on this problem. Normally, the written proposal must be prepared over a specified time period of 30 consecutive days. Except in unusual circumstances, the problem must be distinctly different from the dissertation problem.

The examining committee evaluates the research proposal upon completion. If the committee judges it satisfactory, the oral examination part of the comprehensive examination is held. The oral examination is based on the research proposal but may also cover areas peripheral to the proposal.

A student must pass both parts of the examination. Failure of either part constitutes an unsatisfactory grade on the entire examination. An aspirant who receives a grade of unsatisfactory may repeat the examination upon the recommendation of the examining committee, but the exam may not be taken more than twice. The examination may not be repeated until at least 90 days have elapsed since the unsuccessful attempt. On receipt of a grade of Honors or Satisfactory on the comprehensive examination, the aspirant is admitted to candidacy for the degree of Doctor of Philosophy.

Ph.D. Dissertation and Final Oral Examination

The doctoral dissertation, based on independent research conducted by the candidate, constitutes the final phase of the doctoral work and must be completed within the prescribed time constraints. Upon acceptance of the dissertation by the advisory committee, the candidate defends the dissertation in a final oral examination. The examining committee consists of at least 5 persons, including the advisory committee members and at least 1 person from outside the department.

MS to PhD Program

If a student obtains their MS degree in Chemical or Petroleum Engineering from the University of Kansas and plans to continue on into the doctoral program, then the GPA from the core courses will be used as the basis for entering the PhD program. If the student obtained their MS degree in Chemical or Petroleum Engineering (or very closely related fields) from another university, then the student's MS course work is evaluated by:

The Graduate Standards Committee (GSC) will determine if 1 to 5 (4 PE) of their MS core courses will count toward the requirements to become a PhD aspirant. A minimum of 45 credits must be completed at KU for Ph.D. degree completion.
