Challenges Of Porosity-Based Pore Pressure Prediction ...

Observations during drilling, however, coupled with interpretation of LWD/MWD data permit updating of the prediction in real time. This paper examines the methodology and assumptions involved in extracting pore pressure prediction from seismic and wireline data sources, and strives to comment on the challenges which exist in particular ...

Quantitative analysis of shales by KBr-FTIR and micro-FTIR

Jan 15, 2014· The purpose of this paper is to demonstrate and discuss the feasibility of KBr-FTIR and reflectance micro-FTIR for quantitative analyses of organic and mineralogical compositions in shales. Quantification results of shales derived by independent techniques, i.e. FTIR, XRD, and chemical analysis are also compared. 2.

introduction A key factor needed for the use of seismic-wave velocities in hydrocarbon exploration and reservoir characterization is an understanding of what seismic waves can tell about the intrinsic parameters (composition, texture, fluid saturation) and extrinsic parameters (state of stress, temperature, pore pressure) of rocks in situ.

US8838428B2 - Methods and systems to volumetrically ...

Methods for identifying hydrocarbon plays include applying predictive models to sediment fill volume(s) to provide play-element volume(s) representing at least one play element. Each play-element volume represents at least 1) qualities of the at least one play element and 2) a probability that the at least one play element satisfies determined criteria for each of a plurality of locations ...

introduction Obtaining an estimate for the chance of success is an important part of the decision to drill or not to drill a prospect. Many different methods are used to obtain such an estimate (see, for example, Rose, 1987, 1992, 2001; White, 1993).

Aug 16, 2019· The plethora of micro (μm)–to–mega (≥ 10 to ≤ 100 m) scale heterogeneities in marginal marine siliciclastic reservoirs makes their petrophysical analysis often cumbersome, and thus yield unrealistic reservoir parameters. Micro-scale heterogeneities typically occur at the microscopic scale, while the mega-scale is observable at the outcrop scale. A good understanding of the possible ...

Jun 04, 2018· 1 Introduction. The latest rupture of the Main Himalayan Thrust (MHT), the 2015 M w 7.8 Gorkha earthquake, was likely limited in size by changes in the fault geometry along strike and dip (Hubbard et al., 2016).The rupture occurred primarily on a subhorizontal décollement bounded on several or all sides by more steeply dipping ramps (Elliott et al., 2016; Galetzka et al., 2015; Hubbard et al ...

Fracturing and Porosity Channeling in Fluid Overpressure ...

At the time of energy transition, it is important to be able to predict the effects of fluid overpressures in different geological scenarios as these can lead to the development of hydrofractures and dilating high-porosity zones. In order to develop an understanding of the complexity of the resulting effective stress fields, fracture and failure patterns, and potential fluid drainage, we study ...

Multivariate data analysis - AAPG Wiki

Feb 02, 2016· Multivariate observations are best organized and manipulated as a matrix of sample values, of size (n × P), where n is the number of samples and P is the number of attributes or variables. For example, a (5 × 3) matrix might represent five core samples at different depths on which frequencies of occurrence of three different fossils are recorded.

Jan 15, 2019· The Pennsylvanian–Middle Triassic Cooper Basin is Australia's premier conventional onshore hydrocarbon-producing province. The basin also hosts a range of unconventional gas play types, including basin-centered gas and tight gas accumulations, deep dry coal gas associated with the Patchawarra and Toolachee Formations, and the Murteree and Roseneath shale gas plays.
