... Abstract It is a very challenging task to produce highly viscous and extra heavy crude oil from the Jodhpur Sandstone reservoir of Baghewala field of Western Rajasthan in India by any conventional methods. The crude obtained are having API in the range of 14 – 17 and viscosity ranging from 8000...

... 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...

... Abstract One of Sudanese fields has a heavy crude oil which has a high Total Acid Number (TAN) and high viscosity, can cause a lot of problems in production operation, transport, and storage facilities. The effect of ethanol dilution on the rheological properties of crude (especially...

... Organic Deposit (HMWOD) that have caused a significant pressure drop in the tubing, which consequently restrict oil production and tested to only disperse at above 90°C. It was suspected that the deposit was a naturally-occurring component of the crude oil itself, separating from the bulk of the crude...

... Abstract Banyu Urip crude contains 26% wax which can provide flow assurance (FA) challenges in a stabilized crude pipeline exposed to lower temperatures. Injection of Pour Point Depressant (PPD) chemicals has widely been considered as an effective method to ensure flow assurance for moderate...

... Abstract Highly paraffinic (or waxy) crude oil can cause significant problems in the pipelines due to wax–oil gel blockage resulting from the precipitation of the wax components. Once blockage of the pipeline occurs and flow ceases, the pipeline flow cannot be restarted with the original steady...

The other two plugs were formed when trying to open the downhole safety valves by pumping crude to return the wells to production after they were shut-in due to hurricane evacuation. Several unsuccessful attempts to melt the hydrate blockage included pumping...

... because of the low gravity of the crude. The solution was to engineer a new motor protection system that was virtually elastomer free. The design utilizes metal bellows, high-density oil for gravity separation protection and high-grade o-rings. This design resulted in the first ESP motor protection system...
