Forskningsområder

My research interests are in designing and testing new and/or more environmentally-friendly chemicals for the oil and gas industry. I have also written a book called ?Production Chemicals for the Oil and Gas Industry,? the second edition of which was published by CRC Press in March 2014 (available on well-known internet bookshops). It has about 3300 references.

 

My main research interest is in designing, synthesising and testing new low dosage gas hydrate inhibitors (LDHIs) and understanding the mechanisms of both these and LDHIs already commercialised.

 

LDHIs are a fairly new technology for preventing gas hydrate plugging of oil and gas pipelines, both offshore and in colder climates, but their application can lead to multi-million dollar savings compared to using traditional methods such as using thermodynamic inhibitors (methanol, glycols etc.). We are designing and investigating both classes of LDHIs called kinetic hydrate inhibitors (KHIs) and anti-agglomerants (AAs). KHIs are water-soluble polymers that delay gas hydrate nucleation and crystal growth, whereas AAs are surfactants that allow gas hydrates to form but prevent them from plugging pipelines by converting them to a transportable slurry in a liquid hydrocarbon phase. We have collaborations with many universities worldwide as well as several chemical suppliers. Besides testing of LDHIs in rocking cells, wheels and autoclaves, we also carry out in-house OECD306 biodegradation tests but use external companies for other ecotoxicology tests.

 

Some types of LDHI are already in commercial use but there are demands in some sectors, such as offshore Norway, for more environmentally-friendly inhibitors as well as products which are cheaper, more compatible or have higher performance. Several LDHIs we have discovered have been patented and the technology rights transferred to a spin-off company, Eco Inhibitors established in 2011. Products include greener KHIs, non-polymeric KHIs, KHI synergists, as well as greener AAs. Eco Inhibitors also carries out consultancy work on gas hydrate control, particularly screening LDHIs. 

 

Another area of research at UiS is synthesising and testing new and more environmentally-friendly scale inhibitors. Prevention of scales such as calcium carbonate and barium sulphate are commonly done with aminophosphonates and various polymers with carboxylate, phosphonate/phosphinate or sulphonate groups. Few of these scale inhibitors are biodegradable. We have been developing new biodegradable scale inhibitors containing phosphorus for easy detection, as well as scale inhibitors that also function as kinetic hydrate inhibitors.

 

We also carry out  research on other production chemical issues, such as asphaltene, wax and corrosion inhibition, demulsifiers and defoamers.
