3D Geological Modeling & Stochastic Modeling
Reservoir simulation provides a powerful tool for reservoir optimization and management. However, the reliability of reservoir simulation forecasts are strongly dependent on the accuracy of the field geological model. The geological model must give the physical shape and volume of the reservoir as well as the internal segmentation of the reservoir including layers, faults, pinch outs, and unconformities. If these features are not well defined then the resulting simulation forecasts may be significantly in error.
In practice, there are always many uncertainties in the geological model for a reservoir because of the scarcity of data. Well data such as cores and well logs sample only a tiny fraction of the volume of the reservoir and there is often considerable subjective interpretation in the development of the geological model. 3D seismic data can provide in some cases, an enormous amount of information about the internal architecture of the reservoir which is useful for defining the underlying trends of various surfaces obtained from mapping of the hard data at the wells.
Helix has considerable experience in developing realistic geological models using the latest geoscience software tools such as Petrel and IRAP RMS, and up-scaling these models to commercial reservoir simulators. These geological models were developed by integrating all the available data including seismic, petrophysics, geology, and engineering data. Helix has considerable experience in the application of stochastic methods to model the facies distribution in the reservoir as well as the distribution of rock property attributes such as porosity or permeability.

Geosciences Data Integration & Database Development
|
One of the major difficulties in any reservoir study is the limited amount of data available to describe the large and complex reservoir volume. Thus, it is crucial that the all data from the different geoscience disciplines be used to generate the best possible earth model. One of the most difficult and time consuming tasks in building a realistic field geological model, especially for large fields with large number of wells, is integrating the data from the different geoscience disciplines and be able to stream this data seamlessly between the different geoscience software tools. Using different data sources to quality control an earth model is also important to weed out erroneous data and build a realistic model which can provide accurate forecasts of field performance.Using different data sources to quality control an earth model is also important to weed out erroneous data and build a realistic model which can provide accurate forecasts of field performance.
At Helix, our experience with many of the commonly used geoscience software applications coupled with our expertise in database management, allows us to complete large-scale projects in an effective and timely manner.

Integrated Multi-Disciplinary Field Studies
Integrated Multi-Disciplinary Field Studies
Helix has been involved in many integrated reservoir studies which include all the subsurface disciplines including geophysics, petrophysics, geology and engineering. By working in an integrated manner, the best possible reservoir description with the available data can be achieved and this leads to more reliable predictions of reservoir performance from the final reservoir models.
