Taking Dimensions And Rock Properties In Reservoir Property Modeling

By Joseph Russell


In the zone of oil and gas, there has always been the need of enhancing reserves estimates as this enable decision making when it comes to advancing the outcomes. The progress incorporates future results, creating of more wells and extending of reservoir estimations. The whole process can only be supported through Reservoir Property Modeling as this incorporates building petroleum pool computer models that do the work.

The reservoir replica looks the same as the reservoir physical space through a series of discrete cells sketched by a regular or irregular grid. The cells exhibition is ordinarily three-dimensional through 1D and 2D forms which at times they can be applied. The worth of features, for instance, porosity, permeability, and saturation are linked per each cell. They are also totally meant to take place regularly through the reservoir volume which is signified by the cell.

At times a single shared earth model is utilized for both reasons. More frequently, a geological model is established at a considerably high resolution. Also, a coarser crisscross for the pool simulation replica is built with mostly two arrangement of magnitude fewer cells. Useful values of aspects for the simulation model are gotten from the geological replica through the up scaling process. Then again, if there is no geological model that exists, the simulation model attribute values can be retrieved through the procedure of sampling geological maps.

Any form of uncertainty in pool aspect values are normally checked by creating different actualization s sets. The performance of the resulting models is able to portray the linked level of monetary vagueness. The characterization is normally utilized to show modeling exercises to the degree when a model of simulation is made to show the streaming fluids. There is also the usage of software that is commercial oriented when dealing with the phases of evaluation, simulation, and creation of the pool models.

The progressions needed to build pool models are shown by the expression Seismic to simulation. The procedure is victorious if the model precisely shows the initial well logs, production history, and seismic data. Pool models are built to have a better comprehending of the subsurface that facilitates production planning, reserves estimation, and well placement.

All models are created according to measurements provided in well records, seismic assessments and production verification s. Seismic to simulation ensure there is quantitative linking of data with the model which is update able. The model is established by bringing together geophysicists, geologists, and engineers,

While reflecting on the rock properties and even lithotypes, there is application of geostatistical inversion in creating the variety of plausible seismic-derived models of the rock. That is achieved at heterogeneity and adequate vertical resolution ensuring permitting transfer of strati-graphic grid and flow of simulation to correctly alter seismic-derived data to the geologic model and flow model. That is achieved for model corroboration and ranking to take care of the model that is good for the whole data. The primary procedures in seismic to simulation are established to build a relationship between rock features and elastic properties. That is accomplished to gain the same ground between well logs and seismic records.

Likewise, there is the capturing of intensity well logs dimensions, and this provides great-resolution vertical data, and that are utilized into the inter-well region. Seismic records are captured inappropriate time to come up with the lateral data despite that being just limited to vertical resolution. After the linkage, there is application of seismic and well to fabricate a fine-scale subsurface 3D replica.
