Organophosphorus compounds are well known as oilfield scale inhibitors. Earlier work showed that a series of new and well-known bone-targeting drugs incorporating non-toxic bisphosphonates (BPs) (PO3H2–C–PO3H2) gave good inhibition performance against calcite based on produced water from the Heidrun oilfield, Norwegian Sea, Norway. However, these chemicals only moderate calcium compatibility ac...

This study focuses on the development of a hybrid biological reactor for treatment synthetic oilfield produced water. To face increasingly strict regulations concerning water discharge, fixed bed (FBHBR) containing combination free activated sludge and biofilm support was compared to conventional (CAS). After gradual microbial acclimation, 133-day experiment showed that both bioreactors were ab...

In today’s society, with the continuous growth of energy demand, Bohai Oilfield, as an important offshore oil resource base in China, is facing increasingly severe challenges while contributing to national security. order improve quality water injection oilfield and gradually achieve efficient stable production, Oilfield has launched a well pressure optimization project, focusing on improving e...

Two of the most fundamental concepts in the current debate about future oil supply are oilfield decline rates and depletion rates. These concepts are related, but not identical. This paper clarifies the definitions of these concepts, summarizes the underlying theory and empirically estimates decline and depletion rates for different categories of oilfield. A database of 880 post-peak fields is ...

This experimental paper deals with the development of a hybrid biological reactor for treatment synthetic oilfield produced water under an increase in total dissolved solids (TDS) concentration. To comply strengthening regulations concerning discharge and peculiar compositions, moving bed biofilm (MBBR) consisting combination free activated sludge supports was compared to fixed (FBHBR) support....
