Abstract:

Equations of state (EoS) were originally developed to simulate volumetric changes with pressure and temperature of hydrocarbon gas mixtures, but today’s reservoir and flow assurance engineer expect an EoS to provide much more information than that. For all kinds of reservoir fluids equations of state are expected to give reliable results for saturation points, phase compositions as well as derived properties like sound velocities and Joule-Thomson coefficients. The expectations may also include modeling of precipitation of solid or solid-like heavy material as for example wax and asphaltenes.

All commonly used cubic equations of state can do a good job when it comes to modeling of reservoir fluid properties. The key to a valid EoS model is a representative fluid sample and compositional analysis. The fluid is afterwards to be characterized for the selected equation of state taking into account the chemical nature of the fluid. A secondary challenge is to carefully select the PVT data to be measured and matched considering the requirements to the final EoS model.

The presentation will outline recommended procedures for getting representative fluid compositions and pitfalls to be aware of when developing EoS models. The example applications will include classical fluid modeling, models for fluids with gas injection and modeling of wax and asphaltene precipitation.

Abstract:

An integrated reservoir study was performed on Miocene Stevens sandstones at Canfield Ranch Field, San Joaquin Basin, California. The Miocene Stevens sandstones are submarine fan and channel deposits that are characterized by variable lateral extent. More than 150 , 40 acre spacing wells were drilled in the Stevens interval since 1938. Two infill wells drilled in 2007 did not meet the operator’s expectations, highlighting infill drilling uncertainty even in a field that has relatively abundant well control. An integrated reservoir study was conducted to better understand the reservoir geology, and its control on the subsurface fluid and production. One of the challenges in this study was to integrate various data from different sources and different vintages. Reconciling inconsistencies in the data from various disciplines and sources were critical to reduce the uncertainty in characterizing the reservoir and to construct a fit-for-purpose model for operational use.

Kuala Lumpur section had organised an exciting 'Bowling Tournament' in Cosmic Bowl, Mid Valley on the last 24th April this year. Most of major oil and gas companies participated in the event. Its a big turn out from them as you may see from the photos.

Abstract:

The first intelligent completion was installed in 1997, in the last 13 years a number of major oil companies have embraced the technology while others have stood by and watched the technology develop without deploying any completions utilizing these systems.

This presentation will introduce the basic concepts of intelligent completions and the differences between these completions when compared to standard completions. What impact these differences have on the overall design phase of the completion and the challenges facing companies in progressing from the conceptual design to implementation. 

Experience of successful approaches will be presented and lessons learned from operators who routinely install intelligent completions will be discussed.  While every well will not be an intelligent well, an understanding of the concepts and philosophies of design may just help to select which wells and fields should and should not be considered for investment in the technology.
