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.

Learning outcome

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.

Contents

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.)
Water injection chemicals - biocides, oxygen scavengers, desulphation, tracers, water-based drag reducers, IOR chemicals.
Flow assurance issues - corrosion, microbiological problems, H2S scavenging, wax/paraffin, gas hydrates, scaling, naphthenates. Integration with reservoir management, HPHT, subsea tie-backs, chemical injection, wintering.
Processing chemicals - demulsifiers, flocculants, defoamers
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.

Required prerequisite knowledge

The student must have taken and passed Chemistry and Environmental Science (KJE100) or equivalent subject.

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.  

Recommended prerequisites

KJE150 General Chemistry, KJE200 Organic Chemistry 1, KJE220 Inorganic Chemistry

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 surfactantsinstrumental methods to analyse chemicalsthe oil and gas industry in general (from drilling to production and on to the refinery)

Exam

Dissertation and oral exam
Weight Duration Mark Supporting materials
Dissertation A - F
Oral exam A - F
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.
