... large changes in pressure and temperature. Fundamental understanding of the behaviour of the fluids and flow is key to the flow assurance discipline, and to the efficient design and operation of such production systems. Techniques for visualising and modelling the flow, required to manage the various...

... temperatures below the wax appearance temperature (WAT) through the use of thick insulation to maintain heat from the reservoir. The most common approach for managing deposited wax is pigging to physically scrape and remove the wax. Due to cost reductions in design or operational challenges (e.g...

... ABSTRACT Steam Assisted Gravity Drainage (SAGD) has emerged as a promising in-situ oil recovery method from Athabasca oil sand deposits in Alberta, Canada. Despite numerous successes, optimal SAGD operations remain a major challenge. Present day operations depend on CAPEX intensive...

... ABSTRACT Multiphase flows of high CO 2 content fluids in the production stream of a Brazilian presalt field are analyzed during a transient (shut-in/restart) operation. Simulations were performed using the 1D gas-liquid module of LedaFlow ® . PVT tables were generated for mixtures of 20–50...

... Abstract This paper describes an experimental and numerical investigation of the two-phase water-air flow at the inlet of an electrical submersible pump (ESP). The main goal was to find a means of directly monitoring pump operation to avoid the onset of surging. The particular geometry...

... Abstract Compact and subsea separation methods have become increasingly commonplace in many offshore oil and gas operations. Compact equipment have been instrumental in debottlenecking existing operations, as well as enabling production in some cases. While the benefits are plenty, the primary...

... for this. However, pumps installed in parallel require special attention in regard to upstream flow splitting. This is especially true for multiphase pumps being fed by wells which are far away, as long gas slugs have to be envisaged. The operation of multiphase pumps requires observing up- and downstream flow...

... Abstract Multiphase flow simulations using commercially available software programs have been performed to replicate bypass pigging field tests with the objective of assessing the simulators' suitability for predicting the outcome of field bypass pigging operations. Design Engineers rely...

..., the obtained predictions do not exhibit the same level of robustness, particularly believed by the smaller concentration of studies on such type of fluid flow and also by the scarcity of operational data that could contribute in the enhancement of the modeling and associated simulation code tools. This work...

... ABSTRACT A subsea field in the deepwater of the Gulf of Mexico will be installed and commissioned in phases. The uniqueness of the subsea construction activities presented several flowline displacement operational challenges with oil circulation and seawater circulation procedures...

... ABSTRACT This paper describes how multiphase flow simulation was used to assist the clean-up operation of an offshore oil well. The modeling complex involves the simultaneous transient flow of nitrogen, brine, and reservoir hydrocarbons. The dynamic simulation was used to decide the minimum...
