Abstract: There is described an invert emulsion wellbore fluid that includes: an oleaginous external phase; a non-oleaginous internal phase, wherein a ratio of the oleaginous external phase and non-oleaginous internal phase is less than 50:50 by volume; an emulsifier; and a rheological additive comprising a sulphonated polymer formed from 100 to 10,000 monomers. There is also described a method of drilling a subterranean hole using the invert emulsion drilling fluid.

Abstract: Use of a polypeptide or protein with amino acid sequence corresponding substantially to AFP-type III HPLC 12 as additive in a product for improvement of said product, said improvement residing in improved properties of modification of ice crystal growth processes influencing size and shape characteristics of ice in particular in regrowth thereby e.g. minimising potential freezing damage e.g. by preventing or inhibiting ice recrystallisation of the product upon freezing, said use occurring in a manner known per se for anti freeze peptides to obtain higher specific modification activity in particular antifreeze activity than obtainable with the same amount of Winter Flounder AFP.
