INTRODUCTION - OIL & GAS RESERVE ESTIMATION SOFTWARE
Geologists and Geophysicists in the Oil and Gas Industry require the help of a Petro physicist to provide them with the required information regarding the properties of different rocks. The introduction of Petro physics software will help these professionals to estimate the oil and gas reserves present in a particular Area of Interest.
Reserve Estimation Methods
There two more common methods of oil and gas reserve estimation are volumetric estimation and material balance. Other methods include decline curve analysis and reservoir stimulation.
1)Volumetric Estimation
Volumetric estimation is the method applied during the early delineation and development of a field. In this method, standard reserve equation is used with appropriate reservoir parameters which include

1)Volumetric Estimation
Volumetric estimation is the method applied during the early delineation and development of a field. In this method, standard reserve equation is used with appropriate reservoir parameters which include
- Area, Thickness, Porosity, Water Saturation, Formation Volume Factor, Recovery Factor.
- Determination of Rock Volume, Determination of Average Porosity, Determination of Water Saturation to obtain hydrocarbon saturation and volume correction of hydrocarbon at atmospheric pressure and temperature.
- Seismic, Well Log, Core Data, Bottom Hole Pressure, Temperature Data, Fluid Sample Information, Well test result
Summary In simple words, volume of the particular field is calculated by measuring its area in square kilometers and then multiplying the area with the depth of the field. The volume will include the stones, hydrocarbons and space. The percentage of the stones and space will be subtracted from the total percentage of the field which gives the percentage of the hydrocarbons present in the field. Thus, the amount of hydrocarbons present in the field is calculated.
2) Material Balance Material balance is the more reliable method as the depletion proceeds and adequate data is made available. The production data includes production volume, reservoir pressure and temperature, fluid analysis data, log data, core data and drive mechanism.
3) Decline Curve Analysis Decline curve analysis is the method used in which production decline curve is analyzed which provides the estimation of remaining oil and gas reserves, future expected production rate, remaining productive life of well or reservoir.
Below is a video which demonstrates some of what we are trying to achieve by making this software.
