Petrophysical Evaluation of Low Resistivity Sandstone Reservoirs

Journal of Canadian Petroleum Technology, 2000
Abstract There are many reasons for low resistivity pay zones. It is of crucial importance to know the origin of this phenomenon. The problem with these zones is that the resistivity data interpretation indicates high water saturation, but oil or even dry oil will be produced.

Horizontal Well Placement and Petrophysical Evaluation Using LWD

SPE Annual Technical Conference and Exhibition, 1995
Abstract A well recently drilled in the Gulf of Mexico utilized new developments in logging while drilling (LWD) technology to allow a horizontal wellbore to be accurately placed in difficult targets. Simultaneously, high-quality petrophysical log measurements were taken, allowing very detailed formation evaluation. An instrumented motor

Petrophysical evaluation of gas-hydrate formations

Petroleum Geoscience, 2008
ABSTRACT Gas hydrates are recognized as a massive source of fossil fuel that could be far in excess of conventional hydrocarbon resources. The evaluation of formations that contain gas hydrates is therefore receiving renewed emphasis through contemporary petrophysical technology. A key factor is the use of logging-while-drilling (LWD) to sense hydrate-

Petrophysical Aspects of Bazgen Deposites Formation Evaluation

Proceedings, 2014
Authors compare bazhen sediments to gas shale using empirical data. They illustrate how specific are bazhen sediments and focus on the ways of using those specific features to formation evaluation of bazhen deposits. Proposed new algorithms and explained several practical cases.

Evaluation of Petrophysical Relations by Using Cluster Analysis

SPE Russian Petroleum Technology Conference, 2020
Abstract The paper describes the methodological aspects of building one-dimensional (1D) models of the physical and mechanical properties of rocks in the near-wellbore space through building statistical correlations of petrophysical and physical and mechanical properties based on the integrated field geological and geophysical ...

Integrating Petrophysical Evaluations and Rock Physics

Proceedings, 2018
We have developed an optimization methodology to consistently integrate petrophysical evaluations and the construction of rock physics models using multiple wells. This approach allows exploring the different parameters/coefficients used both for the evaluation and rock physics model, while ensuring complete repeatability and traceability of results ...

HESPER: An Expert System for Petrophysical Formation Evaluation

Proceedings of European Petroleum Conference, 1988
ABSTRACT A prototype expert system for formation evaluation is introduced and discussed, beginning with the rationale for its development, and presenting briefly qualitative assessments and tests of its performance. The background and definition of petrophysical formation evaluation is clarified, and the specific ...

A Deep Autoregressive Model for Multiple Petrophysical Evaluations

Abu Dhabi International Petroleum Exhibition & Conference, 2020
Abstract Deterministic methods of petrophysical evaluation is made complicated by petrophysical and geological heterogeneity within the formation even though Petrophysical logs provide most of the subsurface data to an exploration geologist. Biases between the calculated values of different petrophysical properties namely, final-porosity,
