... ABSTRACT: A methodology for remote pore pressure prediction using seismic attributes is presented, based on rock physics responses to various overpressuring mechanisms. A series of laboratory acoustic tests were performed on reservoir sandstones and shales, simulating normal compaction...

... process and the well was completed successfully with minimal wellbore stability problems. 1. INTRODUCTION Traditional approaches to casing design and mud weight selection have typically been based on predicted pore pressures and empirically determined fracture gradients. The resulting mud weights...

... geomechanical modeling can bridge the gap by coupling physically realistic and mechanically rigorous analyses that yield testable predictions. Stratigraphic and structural data sets based on seismic and well data yield 3D geologic framework models (GFM). The GFM can be restored to an undeformed configuration...

Pore size information, NMR response and Formation factor are also calculated on the images. Empirical correlations linking...

... ABSTRACT: Pre-drill pore pressure and fracture gradient predictions obtained from seismic velocity data are an important component of any well design. Although there are significant uncertainties associated with these analyses, few methods have been proposed to quantify them. We present here...

... by examining several field applications which include validation (Class A prediction). 1. INTRODUCTION Selection of the wellbore completion type is a major design issue as it directly impacts the associated capital and operating costs and short- and long-term production potential. This issue...

... ABSTRACT: It is the scope of this work to present an analytical model for sand rate, and to compare its predictions to experi-mental observations as well as numerical simulations, in order to illustrate possible mechanisms involved in the sand production process. The extent to which it can...

... of the effect of temperature on the fracture gradient was performed in a shallow sand/shale sequence in a South Texas well. Pre -test modeling of thermal effects using a simple elastic model predicted that an increase in mud temperature of 33°C would result in an increase in the minimum stress of approximately...

...) within otherwise porous, opening-mode fractures, and the presence of an aperture size threshold below which fractures are completely filled and above which porosity is preserved. Significant progress has been made as well in theoretical fracture mechanics and geomechanical modeling, allowing prediction...

... ABSTRACT: Here we present the results of a geo-mechanical study combined with a new way of 4D interpretation, applied to a depleting offshore gas condensate field. The 4D interpretation uses the predicted stress changes from the geo-mechanical study, by bringing them to the seismic domain...

All slope modeling programs results contained slight inaccuracy when compared to the actual slope. 1. INTRODUCTION Predicting the stability...

Risk analysis is an excellent methodology for adding a quality rating to geomechanical predictions; however, it is most relevant when sufficient data is available (i.e., a statistically...

In this context it is emphasized that, based on a continuous evaluation of geological and geotechnical monitoring data, the predicted geological model is adjusted to the actual conditions. Based on the updated model, excavation and support is adjusted accordingly. The principal...
