The course will teach about the chemical processes, chemical problems and chemical treatments that are used in the production phase of oil and gas fields, both onland and offshore. This includes some downhole stimulation methods, flow assurance issues in the well and flow lines and processing problems. Environmental issues will also be discussed.
The course provides an introduction to the production phase of an oil or gas field see from a chemical perspective. Often, the unsung heroes of the petroleum industry, the production chemists and engineers are the technologists that keep the oil and gas flowing.
The topics within the curriculum include:
Production well and stimulation methods - acidising and scale removal, water and gas shut-off, chemical sand control, liquid unloading of wells, asphaltene and scale control (including squeeze treatments, downhole injection etc.)
Environmental and health issues - ecotoxicological tests and interpretations, OSPARCOM, HOCNF, HMS on platforms, human hazard coding, heavy metals.
Other topics: drag reduction, heavy oil, hydrotesting.
The students will learn about the chemical processes, chemical problems and chemical treatments that are used in the production phase of oil and gas fields, both onland and offshore. This includes some downhole stimulation methods, flow assurance issues and processing problems. Environmental issues especially for offshore discharge limits are also included.
Required prerequisite knowledge
One of the following alternatives: KJE101 Fundamental Chemistry KJE150 General Chemistry
The student must have taken and passed General Chemistry (KJE150), Fundamental chemistry (KJE101) or equivalent courses.
Students must have a basic undertanding of the naming of inorganic compounds and organic chemicals (including aromaticity and basic functional groups in organic molecules), equilibrium, amounts of chemicals (moles, weight.%, ppm/ppb), redox reactions, solubility, acids/bases.
It will be very useful to have some understanding of:
kinetics and thermodynamics (part of General Chemistry course KJE150)
the structures and solution properties of polymers and surfactants
instrumental methods to analyse chemicals
the oil and gas industry in general (from drilling to production and on to the refinery)
Dissertation and oral exam
Form of assessment
Written work - a project report - on a theme related to the course. Mimimum 3000 words plus figures and references. The student can use recommended literature and other information. The student can propose a topic that he / she might like to write about (to be approved by the course leader), also from contacts made in the chemical and petroleum industry.
Students are required to attend a minimum of 50% of all lectures, in order to be able to take the exam.
The course is available for master students in Biological Chemistry, Environmental Engineering and Petroleum Technology.
Other students may be accepted as long as they fulfill the admission requirements.
There must be an early dialogue between the course coordinator, the student representative and the students. The purpose is feedback from the students for changes and adjustments in the course for the current semester.In addition, a digital course evaluation must be carried out at least every three years. Its purpose is to gather the students experiences with the course.
