Rock Flow Dynamics summed up what was done in the tNavigator in 2020 and outlined plans for 2021.
For several years in a row, the company has been releasing four versions of the tNavigator software package a year. It is worth noting that 2020 was no exception: the development and testing of v. 20.2, 20.3, and 20.4 was done by RFD employees working remotely. Updates and improvements have been made to the tNavigator calculation part and all software modules. Moreover, we introduced new modules: Well Designer, Geosteering 2.0, hydraulic fracturing simulator. In 2020, there were over 500 slides in the presentations describing key changes. Detailed information can be found on the website rfdyn.com.
There have been significant changes in the workflows as well. In the new version, this tool looks much more user-friendly and compact. So, the operations that took 70 lines of code can now fit in just 20. What is more, now all subprojects can be launched through the workflow, and the uncertainty analysis and auto-adaptation module can fully manage this project. We also added the first implementation of the functionality that allows running a workflow on a cluster.
The company continues to actively develop the usage of graphics processors, which allows enables us to overcome the computational speed barrier that exists on conventional CPUs. The latest versions of tNavigator support Nvidia Ampere GPUs, MultiGPU, and now it is possible to carry out perform compositional calculations on the GPU.
The geography of users has been expanded, and, in fact, among the company’s clients, there is a growing interest in one of the youngest modules – the Geology Designer. Over the past year, the module has received several new functional features and now includes seismic data interpretation, 2D and 3D geological modeling, mapping, and reserves calculation. We also added a specialized machine learning method – the Amazonas algorithm. A Rock Flow Dynamics senior geologist developed this stochastic method of modeling geological systems with an arbitrary distribution of properties, including statistically unsteady ones, based on non-parametric statistics. Moreover, in the latest versions of tNavigator, a unique opportunity has become available to users: now it is possible to calculate a geological model on a cluster.
Of course, the company’s main asset is our developers and experts in hydrodynamic and geological modeling. All of them are dedicated enthusiasts who, from year to year, work to improve our software package and help the users around the world solve any production cases they come across.
This year, Rock Flow Dynamics has expanded its staff by 22 developers; today, the company has 104 specialists responsible for creating numerical and visualization algorithms in C ++, CUDA, Python, flex, and bison, gperf, php. It is estimated that tNavigator modules and utilities consist of more than 12.5 million lines of code.
In 2020, the company recruited 9 more reservoir engineers and geologists. In total, the tNavigator software technical support team includes 54 people in 19 countries. This year alone, they processed and responded to more than 6.5k requests from the software users.
Our plan for 2021 is to continue the development of tNavigator software integration to build up a single unified system that provides an end-to-end workflow from seismic and geology to surface networks, expand the set of artificial intelligence algorithms to optimize a number of tasks, and continue to be the all-time fastest software package for integrated static and dynamic modelling.
