this paper presents the effect of high viscosity oil and two-phase foamy-oil flow on the performance of a single stage centrifugal pump. as a part of this, the applicability of a pipe viscometer to determine the foamy oil viscosity is investigated. unlike previous studies, a sealed fluid tank is used in a closed flow loop to allow conditioning the two-phase mixture to create foamy-oil. furtherm...

Acidizing is a dissolving activity, whether it rock formations or other materials (natural foreign) in reservoir of the rock. To maintain production Jatibarang field, especially Bangodua (BDA) structure, there are 1 well that have experienced short decline since drilling. The properties not good and impurity material (damage). Thus, requiring stimulation form matrix acidizing. Evaluation acid w...
