Upcoming Division Event

Modelling Drainage Footprints of Wells and Fracs Shadows in Conventional & Tight Oil Reservoirs to Reduce Risk on Infills through a Volumetric Simulation 

Speaker: Rocky Mottahedeh, United Oil & Gas Consulting 
Time: 12:00 - 1:00 pm, Thursday, Jan. 30, 2020

VSM is a Volumetric Simulator technology within SMART4D software has been developed for Reservoir Studies. Two such cases in Heavy Oil and Tight Plays will be shared.  
The need from Producers for a faster, accurate and lower cost process to drill ready infills and de-risking for well locations in ultra-high well density cases in Mature Heavy Oil projects was the main need for starting this process.  Through the years VSM was extended to Tight plays. Several hundred wells have been successfully planned and drilled through this VSM technology residing as a Reservoir Engineering module in the geo-model software.   

At very high model resolutions (5-10m geo-cellular spacing), VSM simulator iteratively calculates and matches EURs to a 3D drainage volume within wellbores and individual frac movable oil (SRVs) at various displacement efficiencies. 
Initially a highly representative geo-model of HCPV for the conventional or Unconventional reservoir is developed in SMART4D and downscaled to multi-million (5-10) cells.

Current interest to optimize every aspect of well placement and subsequent completions is the driver to drive costs lower for projects and reduce frac hits to get better wells.      



Rocky Mottahedeh, P. Geol. P.Eng. is the CEO of United Oil & Gas Consulting and SMART4D Geosteering with offices in Calgary and current Clients in the US and Canada.
Rocky’s nearly 40 years’ experience includes a multidisciplinary and integrated approach to geosciences including Geology and Reservoir Engineering. Rocky received a B.A.Sc. from University of Toronto in Geological Engineering in 1981. 
Early interest in variability modelling in 3D and system development to make better workflows for integration of Operations Geology, Drilling systems and Reservoir Engineering has lead into the development of SMART4D in the past 20+ years.

Division Sponsor

Division Profile
The mandate of the Geomodeling Division is to provide CSPG members with opportunities for education and information related to technical developments in the subject areas of geomathematics and computer technologies as they are used in the pursuit of petroleum exploration and development. As a main contribution of the division, technical luncheon presentations are held once a month, usually on the last Wednesday of the month. 

The subjects that are presented in these technical talks include, for example, The latest developments in geomathematical applications, Geological modeling technology, Geostatistical approaches to modeling and risk analysis, Geological case studies using computer technology and the benefits, Digital data organization - storage and retrieval. In addition, ad hoc forums may be organized where members can discuss geomathematical and geological computer issues with experts in the field.The Geomodeling Division does not endorse or promote the use of specific commercial software products, nor does it perform any testing or comparative studies of such products.We do encourage volunteers to present public talks on case histories that illustrate the use of technology and methods.

The success of the Division depends on volunteer participation. CSPG members are encouraged to attend the activities of the Geomodeling Division and to be involved in organizing these activities. Division meetings are held once a month over lunch. If you are interested in joining this committee or if you have suggestions for luncheon talks or other activities, please contact any members of the committee.
