The New Biodegradable Surfactant Drilling Fluid for Offshore HPHT Drilling Environment

The global growing demand for energy has driven oil and gas industry towards drilling deeper wells, many which are subjected to high pressure and high temperature (HPHT) (Burdyn and Wiener, 1956; Larsen, 2007, Godwin et al., 2011). However, this development of deeper oil horizon is halted when conve...
