Paper presented at the SPE/IATMI Asia Pacific Oil & Gas Conference and Exhibition, October 10–12, 2023
Paper Number: SPE-215459-MS
... Abstract High wax content characteristic of Banyu Urip (BU) crude is mitigated by continuous Pour Point Depressant (PPD) injection at multiphase stream. PPD treatment aim to lower Pour Point to 24°C with dosage of 475 ppm. It was observed that PPD dosage started to increase up to 650 ppm...

.... Kartoatmodjo (1990) used a more extensive range of data in his correlation. His crudes originated from South East Asia, California, and Alaska; however, his correlation applies to the flash process only. If Kartoatmodjo's correlation is used for the differential process, it might result in errors of up to 20...

... into the wellbore ( Figure 5 ). These deposit was a naturally-occurring component of the crude oil itself, separating from the bulk of the crude as a consequence of the fluids movement towards the wellbore and the consequent drop in fluid pressure. As such, nano-fluid pilot treatment was considered...
