The inaccurate pred ication o f the pore pressure o ften dam ages the bo reho le during the exp loration and the explo itation. It not on ly obstac les the pro cess of eng ineer ing pro ject, but a lso engende rs b ig econom ic damages. So, the accura te prediction o f pore pressure not on ly p lays an im po rtan t role in determ in ing them ud density and the des ign o f we ll bore structure in drilling, bu t a lso is a key factor fo r dr illing successfully. Th is artic le em phatica lly elaborates about a ser ies of me thods to forecast po re pressure, includ ing the forecast fo r fo rm ation pressure during the pro cess o f dr illing, and it illustrates how to accurate ly forecast pore pressure. F inally, th is article presents som e suggestions po inting to the lim ita tions of m ethod of pred ic tion
