AGB Oil PB Calc Help Overview Overview: Distribution conditions: this software application available free of charge (Freeware), without any advertisement builtin modules, for both commercial and non commercial usage. Purpose: developed for probabilistic (using MonteCarlo method) or deterministic* oil reserves / resources volumetric computation. Algorithms: two standard oil volumetric algorithms available applicable to both probabilistic and deterministic computation methods: #1 Standard
deterministic volumetric method used in Russia / exUSSR Please note, that author assures that software and algorithms were tested before releasing the software, but still he can not be responsible for any possible losses arise from either usage of this software or usage of results computed by this application. In case of any issues, errors in application or suggestion for future development  please contact author using technical support email: <support@agbcorp.ru> Please do not forget to specify name and version of software application you are using and parameters of you device where application installed. Please visit author's web site: www.agbcorp.ru/ to check for additional information, future development plans or to support future application development. Application interface
is bilingual and available in Russian and English. To
switch between languages  just click on flag image
located in the left bottom corner of main application
window. *  for pure deterministic oil reserves /
resources computation author suggest to use separate AGB Oil Calc
application available from AGB Corp. Project
website. Basic rules on volumetric probabilistic / deterministic computations using this application: 1. Correctly select
units** and source computation parameters, taking
into account that application use European system 2. Select computation
algorithm using menu "Algorithm": #1
 Russian / exUSSR volumetric computation algorithm, #2
3. Select required unit
for the computation results. 4. Specify desired
distribution type for probabilistic computation: Norm
 for NORMAL distribution (default value), LogNorm
 5. For probabilistic
computation please select required method to determine
distribution parameters. For NORMAL (Norm) [IMPORTANT
!!!] Please note that if you changed
distribution parameters option or distribution type  application would not 6. Press <Compute>
button for actual computation process. For probabilistic
computation application use 10000 iterations 7. Application would check
acceptability of input parameters and if no error found
would compute result. If any obvious errors Please note, that depends on computation
result units and used algorithm few input fields might be
invisible. Selecting different units or by using "Reset"
option application would switch all input fields back to
visible state. Also please note that there is no on the
fly conversion of input fields values  and it is very
important to select proper units for input fields. You
could use AGB Units
Conversion application (under
development, not yet released) or third party software for
the conversion of input values between units if they are
not available in application. **  depends on result
computation unit selection and computation algorithm
selection some input fields that not required for
particular computation would be invisible to user. To reset application to the default
parameters and units one could use menu option  "Reset" [F]  computation area. Important to select correct units for input value  at present time following units supported: m² (default), th. m², km², ft², mile², acre and hectare. [H eff. o]  effective layer thickness. Important to select correct units for input value  at present time following units supported: m (default), cm, mm, km, ft, yard and mile. [Phie]  effective porosity coefficient. It is possible to specify value either in PU (values between 0 and 1) or in '%' (values between 0% and 100%) [So]  oil saturation coefficient. It is possible to specify value either in PU (values between 0 and 1) or in '%' (values between 0% and 100%) [Θ]  unit less conversion coefficient defining ratio between oil volume at the surface vs oil volume at reservoir conditions (used in Russian / exUSSR Algorithm #1) [Boi]  formation volume factor for oil at initial conditions used in international deterministic oil volumetric algorithm #2, available units: reservoir bbl/stb [Rec]  oil recovery factor. It is possible to specify value either in PU (values between 0 and 1) or in '%' (values between 0% and 100%). If default value of 0.0 used and Const option selected instead of distribution  software would not compute recoverable reserves / resources. [GOR]  gas / oil ratio. Important to select correct units for input value  at present time following units supported: m³/t (default) and scf/stb. If default value of 0.0 used and Const option selected instead of distribution  software would not compute recoverable reserves / resources of gas dissolved in oil. [POS]  probability of success factor coefficient. Value should be bigger then zero and lower or equal to one. POS = 1.0 means that there is no risk. The lower value you specify  the higher corresponding risk would be. If default value of 0.0 used and Const option selected instead of distribution  software would not compute risked recoverable reserves / resources. [ρ(o)]  oil density, available units are: g/cm³, kg/m³ and t/m³ (in Russia usual oil density range between 0.77 and 0.97 g/cm³). Software would ask user to specify density if it is required for selected algorithm and computation parameters. <Compute>  this button would initiate actual volumetric computation. Software checks input values. If any issues with input values noted then error message presented to user. Incorrect values have to be replaced. If no issues noted  application performs computation. {Result unit}  specify required units for the computation: th. t., MBbls, th. m³, th. ft³ 1. Current version of application does not support input volume value instead of area and thickness. But if you got input volume value (obtained for example from geological modeling software package)  it is still possible to use it  by correctly specifying input units for area and thickness, for example if input volume is 750000 m³, then we could select area units as 'm²' and thickness units as 'm' and use value 750000 for area and 1 for thickness. 2. For reference  main range for oil density produced in Russia are within 0.77 to 0.97 g/cm³ 3. Oil conversion coefficient used in computation algorithm for Russia / exUSSR  unit less value, usually less then 1.0, taking into account reduction of oil volume at surface conditions. Oil conversion coefficient = 1/b, where b is volume factor of reservoir oil. 4. In case of international computation algorithm usage, required formation volume factor for oil at initial conditions, Bo [reservoir bbl/stb], could be approximated using following formula: Bo = 1.05 + (N * 0.05), where N = GOR[ft³/bbl] / 100.

"AndroidResources" and "Resources" libraries Donation: This application available free of charge and does not contain any advertisement modules built in. If you find this application useful please support future development by offering small donation  one could do so using "Donation" links on developer web site  PayPal, Yandex.Money, major bank cards supported for that purpose. Another way to help this project is to share the information on this and other applications developed by Alexey Bogdanov (www.agbcorp.ru) using major social networks such as LinkedIn, Facebook, Twitter, e.t.c Thank you beforehand and good luck with your volumetric computations ! Please note that AGB Oil PB Calc and AGB Oil Calc are multiplatform applications available for Android***, Windows, Linux***, MacOS***  please check application web site for additional information. ***  Currently AGB
Oil Calc Linux application available
for Android, Windows and Linux OS, while AGB Oil PB Calc
available only for Windows OS and Linux OS now and
versions for other platforms would be released later this
year. MacOS versions are under development and would
be available some time in the future. Commercial version of AGB Oil PB Calc application
(with extended functionality  AGB Oil PB Calc Pro) also
planned  please check AGB Corp. Project website for
