Taken from the New Straits Times, dateline 2010-02-20:
Universiti Sains Malaysia is introducing its award-winning ViscoLigno, a chemically modified biopolymer that functions as a drilling mud gelling and viscosifying agent. Standing out from other more commonly used additives in mud drilling, the ViscoLigno is made of oil palm waste.
Its inventor, USM Chemical Sciences School lecturer Associate Professor Mohamad Nasir Mohamad Ibrahim, said ViscoLigno would prevent the soil from collapsing during the drilling process.
He said the substance would also allow soil residue to rise to the surface, allowing the drill to go deeper into the earth without getting stuck.
