The complete paper demonstrates the benefits of honoring data measurements from a multitude of potential sources to help engineers do a better job of including more diagnostics into routine operations to provide additional insight and result in improved models and completion designs. This paper updates a previous case study and presents the results of actual implementation of an optimized steam-injection plan based on the model framework. By measuring which tests best predicted the fractures observed at the Hydraulic Fracturing Test Site, Laredo Petroleum developed a method it hopes will improve fracture modeling in other places. In the complete paper, a new, fully coupled implicit tool was used to model an onshore Omani asset with multiple reservoirs, each featuring different fluids and multiple networks. The complete paper aims at a better understanding of the effect of channel content in complex fluvial channel systems on well-test-derivative responses.
The technical challenges imposed by tight well spacing and fracture interactions have become a focal point of recent earnings calls between investors and the leaders of several shale producers. The picture of the future is becoming clearer, and there are fewer oil wells in it. By measuring which tests best predicted the fractures observed at the Hydraulic Fracturing Test Site, Laredo Petroleum developed a method it hopes will improve fracture modeling in other places. A close look at hundreds of feet of fractured core samples suggest that new fracture models are needed to simulate complicated reality.
When it came to decide where to collect a critical sample of fractured rock, a new method for turning microseismic data into a heat map designed to display the most intense fracturing activity was considered. By measuring which tests best predicted the fractures observed at the Hydraulic Fracturing Test Site, Laredo Petroleum developed a method it hopes will improve fracture modeling in other places. A close look at hundreds of feet of fractured core samples suggest that new fracture models are needed to simulate complicated reality.
An Excel-based tool was developed that uses cubic-equation-of-state (EOS) and thermodynamic electrolyte-chemistry modeling to assess sour-production streams. The deepwater industry uses technology qualification (TQ) as a tool to determine which safety barriers are needed, and what level of testing is required. Even without failure data from the field, a method has been developed to quantify the integrity of various components.
PVT (fluid phase and volumetric behavior) impacts flow modeling in the reservoir, production pipes, and surface process facilities. Several special considerations are required for proper PVT description (sampling and modeling) of ultra-tight/shale formations. This course covers the key issues related to PVT in such systems: sampling, PVT lab tests, in-situ versus produced fluid streams, EOS and black-oil modeling, and transport properties such as viscosity and interfacial tension. A short review of non-conventional thermodynamics is also given, including capillarity and confinement on phase equilibria (e.g. Attendees will gain a fundamental understanding of key PVT issues related to development of ultra-tight unconventional resources, from dry gas to gas condensate and high-GOR light oils found in plays such Eagle Ford, Bakken, Montney, Anadarko, and Permian basins.
This 1-day course is an introduction to thermodynamics and pressure-volume-temperature (PVT) and tuning parameters to fit laboratory data. Different analytical models for oil rate predictions such as Butler-Mokrys (1989) and Dunn-Nenniger-Rajan (1989) models will be discussed. Introduction to thermodynamics and pressure-volume-temperature (PVT): basic law such as: Clausius-Clapeyron Equation, Dalton's law, Henry's Law and Raoult's law are explained and practical examples such as temperature reduction in chamber due to NCG injection, and temperature reduction at Azeotropic point in ES-SAGD process will be solved numerically. Pure Solvent Modelling: processes such as VAPEX and Nsolv will be explained, and different theories explaining the pure solvent oil rates such as Butler-Mokrys (1989) and Dunn-Nenniger-Rajan (1989) models will be explained and compared to physical models. Concepts such as onset of asphaltene precipitation will be discussed.
