pore pressure prediction from seismic reflection data in an oil field
pore pressure is an important parameter, in exploration and production of hydrocarbon resources. lack of accurate knowledge about pore pressure, before drilling phase, leads to serious dangers in drilling process. accurate knowledge about distribution of pore pressure in a field, leads to reduce risks in drilling, improve well planning and mud weight calculations. during burial, normally pressu...
متن کاملHow Does Seismic Data Quality Influence Pore Pressure Estimation and Interpretation?
There are two main approaches for pore pressure estimation: geological using basin modeling and geophysical using seismic velocity. In this paper, seismic velocity was used for pore pressure estimation. The impact of the input data quality in terms of signal-to-noise ratio (SNR) and frequency bandwidth on the accuracy of seismic velocity analysis and, ultimately, the reliability of pore pressur...
متن کاملTarget-enclosed seismic imaging
Seismic reflection data can be redatumed to a specified boundary in the subsurface by solving an inverse (or multidimensional deconvolution) problem. The redatumed data can be interpreted as an extended image of the subsurface at the redatuming boundary, depending on the subsurface offset and time. We retrieve targetenclosed extended images by using two redatuming boundaries, which are selected...
متن کاملSeismic interferometry, intrinsic losses and Q-estimation∗
Seismic interferometry is the process of generating new seismic traces from the crosscorrelation, convolution or deconvolution of existing traces. One of the starting assumptions for deriving the representations for seismic interferometry by crosscorrelation is that there is no intrinsic loss in the medium where the recordings are performed. In practice, this condition is not always met. Here, ...
متن کاملSeismic pore pressure prediction with uncertainty using a probabilistic mechanical earth model
We propose a methodology to propagate uncertainties in seismic pore pressure prediction using a 3-D Probabilistic Mechanical Earth Model (P-MEM). An extended form of Bowers formula is used to link pore pressure to seismic velocity, overburden stress, porosity and clay volume. Probability Distribution Functions (PDFs) for all input variables are stored as attributes in the 3-D MEM. An output PDF...
