Reservoir characterization
This paper presents a novel approach to predict reservoir porosity by conditioning seismic data, calibrating seismic impedance inversion, and tailoring rock-physics analysis.
This paper aims to assess the effectiveness of using advanced integrated production-data-analysis techniques for condensate-rich tight gas fields.
This study applies Monte Carlo simulation and an XGBoost regression model to assess the influence of various formations, geologic provinces, tectonic-plate types, and boundary conditions on hydrogen concentrations.

Many startup companies promote the wonders of analytics but few can ensure that the methods used and data generated live up to the hype. -
ConocoPhillips and Statoil Petroleum have signed a joint-sponsorship-development agreement with Visuray Technology to fund development of a downhole cement-integrity-evaluation technology that will have the capability of evaluating cement integrity even behind multiple casing strings.

Widely held images of what happens when a well is fractured often bear little resemblance to what actually happens underground.

In the complete paper, a new assessment of the WAG-hysteresis model, which was developed originally for water-wet conditions, was carried out by automatic history matching of two coreflood experiments in water-wet and mixed-wet conditions.

The authors present the results of a detailed experimental study in which underlying pore-level-displacement physics of two- and three-phase flow in a fractured rock sample is investigated with high-resolution X-ray microtomography techniques.

The F field in the Middle East currently has more than 40 producing wells in the center of the structure. The uneven well distribution limits the understanding of 3D reservoir characterization, particularly in the flank areas.

This study focuses on recent experience in Saudi Arabia with crude-oil compositional analyses during pumpout with a wireline formation tester (WFT).

The resistivity index (RI) of Fontainebleau and Bentheimer sandstones was investigated at ambient and reservoir pressures down to low water saturations. The RI measurements show that both sandstones display Archie behavior at elevated pressure.

The rising cost of fracturing offers a significant incentive for finding ways to avoid unproductive rock. One entrepreneur says he can use standard well logs to target the slice of rock likely produce most, and avoid the rest.
