What is CMG simulator?

It is a simulation program presented by CMG company (computer modeling group)

in Canada, this indos so!tare "ro#ides practical solutions !or oil$gas reser#oir

modeling in reser#oir engineering%

&he use o! this program is to help ma'imie reco#ery o! hydrocarbon assets in the

most e!!icient ay possible using e!!icient production processes, e!!icient

modeling algorithms and easytouse so!tare%

Main parts (so!tare(s)) o! CMG are,

1 *uilder (pre processing applications)

a +tars ( +team, &hermal, and d#anced "rocesses -eser#oir +imulator)

b Gem (Generalied ./uationo!+tate Model Compositional -eser#oir

+imulator)

c Ime' (IMplicit.0plicit *lac 2il +imulator)

3 Winprop (phase beha#ior and property program)

4 45 results

*uilder o! CMG

a reser#oir model !or a blac oil reser#oir can be built by *uilder simulator o!

CMG% It is a combination process o! collecting the results and in!ormation o! the

!ield into one big unit to create the model%

*uilder is an application used in the preparation o! reser#oir simulation models% It

represents the ne't generation in model preparation, sa#ing time, money, and

!rustration o#er con#entional methods%

reser#oir simulation model is a coste!!ecti#e engineering and management tool

that impro#es reco#ery !rom both de#eloped and unde#eloped oil and gas reser#es%

-eser#oir modelling helps maing the most o! e'ploration and production

in#estments%

*uilder maes the design and preparation o! reser#oir models !aster and more

e!!icient than e#er be!ore% It does this by helping engineers na#igate the o!ten

comple' processes in#ol#ed in preparing a model%

*uilder pro#ides a Windos inter!ace hich organies data the ay the engineersees it6 unconstrained by simulator eyords% 7or ne engineers, *uilder can be

an in#aluable training tool, guiding them through the process o! preparing a

simulation model, and enabling them to concentrate on the reser#oir reco#ery

process, not eyord synta'%

s a result, *uilder in con8unction ith CMG9s line o! reser#oir simulators

maes simulation technologies more accessible to all organiations, e#en those

ith little pre#ious e'perience in modelling%

5e#eloped by CMG9s industryleading team o! scientists, engineers and

programmers, *uilder as concei#ed in response to re/uests !rom engineers and

managers around the orld% *uilder ill help you build a reser#oir simulation

model in record time%

*uilder is a M+Windos based so!tare tool that you can use to create simulation

input !iles (datasets) !or CMG simulators% ll three CMG simulators, IM.0, G.M

and +&-+, are supported by *uilder% *uilder co#ers all areas o! data input,

including creating and importing grids and grid properties, locating ells, importing

ell production data, importing or creating !luid models, roc!luid properties, and

initial conditions% *uilder contains a number o! tools !or data manipulation, creating

tables !rom correlations, and data checing% It allos you to #isualie and chec your

data be!ore running a simulation%

+tarting *uilder

"rior to starting *uilder, you should set up a pro8ect directory ithin the CMG&echnologies Launcher% I! you need to con#ert any contour map or mesh map !iles,

this should also be done prior to starting *uilder%

-eser#oir description


3/4

*uilder can create or import the simulation grid and grid properties describing the

#olume o! a reser#oir% *uilder has tools !or the creation o! 45 models !rom 35 maps

o! top o! structure, gross thicness, and other properties %

*uilder also can import o! 45 :static; models !rom se#eral geological modeling

pacages, such as .5+ Gocad, 5GI .arth2IL or G+W&.- model using correlations, Import a !luid

component model created using CMGLAs "
