Modeling groundwater with Visual MODFLOW 3D-Builder
A new approach for maximizing efficiency and reducing uncertainty

The traditional approach for building a numerical model begins with the creation of a finite-difference grid (size, orientation, discretization) followed by the assignment of model properties and boundaries. To increase the quality of the model, the grid is iteratively refined requiring the user to re-work property zones and boundary conditions. This can be a time-consuming process.

Visual MODFLOW 3D-Builder* allows the user to define a grid-independent model boundary, wells, property distributions, boundary conditions and observation points. The model grid is assigned after the conceptual model is developed, allowing for more flexibility in choosing the grid orientation and discretization. Grid refinement can also be easily applied to the conceptual objects, including design of localized grids.

With Visual MODFLOW 3D-Builder, users can design multiple conceptual models for determining the best approach to simulating a specific groundwater environment. This in turns translates to a more accurate model being generated and countless hours saved on reprocessing. Contact us for more information or download a demo today.

New addition to the Diver-NETZ family
SWS Diver-Mate promises faster and more accurate downloads

The completely-redesigned Diver-Mate* can store Diver* data from hundreds of Divers. Used in combination with a DiverDataCable (DDC)*, this downloading unit stores data in a non-volatile memory drive, meaning that even if the battery is empty the data will still be available. A full battery can support more than 10 days of operational use and a LED will indicate when the battery voltage is low.

• A robust way of downloading data.
• Fast data download in the field
• Easily manage Diver-Mate data with Diver-Office
• Store over 1000 full Diver memories
• Eliminate errors on accidentally reprogramming or stopping Diver
• Download hundred of full Divers with one fully charged battery

The new SWS Diver-Mate is designed for simple and fast download of data. increases download efficiency while reducing data transfer errors.

Weixing Guo receives John Hem Award

Weixing Guo, Senior Hydrogeologist at Schlumberger Water Services, is receiving the 2009 John Hem Award. 

The John Hem Excellence in Science and Engineering Award is presented in recognition of significant recent scientific or engineering contributions to the understanding of groundwater. The award is presented annually for significant contributions from either a single publication or a body of works.

This very prestigious award is being granted to Dr. Guo for his contribution to groundwater science and will be shared with his SEAWAT co-author Chris Langevin (USGS). SEAWAT is an open source public domain simulation program resulting from a government/private industry partnership.

Dr. Guo is the second expert at Schlumberger Water Services to be honored with the John Hem Award.  In 1999 Nilson Guiguer, Business Manager Latin America, received the award for his ‘Visual’ Contribution to groundwater modeling.

Water.slb.com expands to include Mining Projects

Schlumberger Water Services is a worldwide leader in providing practical solutions to water-related issues for mining companies. To share this expertise with the world, we have expanded our water.slb.com website to share more in depth information relating specifically to the mining industry.

Our array of services and solutions for mines is now described in detail on the website and a selection of case studies demonstrating our experience is displayed. As a global company we highlight projects in various regions, for instance water resource management for a mine in Chile and an aggregate quarry hydrogeologic investigation in California.

SEG Conference

The Society of Exploration Geophysicists held its Annual Meeting November 9 – 14 in Las Vegas, Nevada. Schlumberger Water Services showcased products and technologies in the Schlumberger pavilion – booth #1143. 

Five noted experts including David White, representing government, private industry and academia, discussed the very timely topic Managing Our Groundwater Resources for the Future and the role of geophysics in groundwater resource management.

This special event drew an international, national, and local audience of groundwater industry professionals, as well as the geophysicists community. Following the SEG Forum on Monday afternoon was an SEG Special Session "Hydrogeophysics in Practice", which featured presentations of case studies demonstrating the application of geophysics to groundwater resource evaluation, mine dewatering, and environmental characterization.

Schlumberger Water Services Training Course Series

The Schlumberger Water Services Training Services Division has been offering a range of educational courses for the past 17 years. Our courses have been designed to decrease the confusion typically associated with technical topics, and include hands-on learning using the world’s most sophisticated software programs. Participants of our courses gain practical insight into a variety of environmental issues, and learn cost-effective techniques to achieve project objectives.

Upcoming SWS Training Courses

1st Open Enrollment Course offered in Indonesia

Schlumberger Water Services partnered with Creative Network Services (CNS), to offer our first open enrollment course in Indonesia. This is part of a greater initiative to increase our exposure and promote training in Asia. 

The VMOD 2 – Applied Groundwater Flow and Solute Transport Modeling course was a success. Miln Harvey, Senior Hydrogeologist and Manager of Schlumberger Water Services’ Training Division, directed the course incorporating MODFLOW, MODPATH, MT3D, Zone Budget, and WinPEST. The course will re-run in Indonesia at the beginning of January, 2009.

Using Hydro GeoAnalyst Cross Sections to Generate Surfaces in Visual MODFLOW 3D-Builder

Visual MODFLOW 3D-Builder is capable of importing 3D cross sections generated by Hydro GeoAnalyst* (HGA). The cross sections from HGA will be stored in the *.3XS file and this will contain the information on the wells and layers of each cross section created. Once you have imported this cross section into your 3D-Builder project, you may view this cross section in the 3D Viewer by right clicking on the data object and selecting 3D Viewer:

A data operation can be performed on the cross section data object to create a new points data object for each model layer interpretation in the cross section. Once the points data objects have been created, these can be used to create surfaces and then horizons for your conceptual model. To access this data operation, right click on the cross section data object and select Settings... In the Settings dialogue box, select the Operations node from the left side.

Currently the only operation available for the cross sections is to convert the model layer interpretation to a points data object. Select Execute to perform the data operation. A confirmation message should appear to indicate that the operation was successful.

Select ‘Ok’ to the message and ‘Ok’ to close the Settings dialogue box. You will now see a points data object for each model interpretation in the Input Tab:

Each of these points data objects will correspond to a different model interpretation in the cross section. The points data objects will be named according to the model interpretation they represent.

Surfaces can be created from the points data objects. Select the points data object you would like to create a surface from, right click and select Create Surface...

In the Create Surface dialogue box, provide a name for the surface or leave the name as the default. Select the green plus button to add the data source from which the surface will be created. By default, the surface will be created using the elevation attribute from the points file. If you would like to change the interpolation settings, please browse to the Interpolation Settings tab.

Select ‘Ok’ to generate the surface. The new surface will be displayed in the Input tab and can be viewed in a 2D or 3D Viewer. You can create surfaces for each of the points data objects. The surfaces will follow the model interpretations from the cross section and can be used to determine the structure of your conceptual model.
