Enhanced Oil Recovery article

What Is It?

Its a term applied to methods used for recovering oil from a petroleum reservoir beyond that recoverable by primary and secondary methods. 

Stages Of Production:

Primary recovery :occurs when a well is initially put into production and the oil flows to surface naturally.


-Secondary recovery :occurs after the reservoir pressure declines and the well no longer flows oil to surface.
-as we take the oil out of the ground, so the pressure in the oil reduces, and the flow slows down.


-Tertiary recovery: involves more technically developed methods such as the injection of steam, chemicals, gases, microbes or heat.

Techniques Involved:

 
EOR includes five methods
Water flooding.
thermal recovery.
 .gas miscible recovery
 chemical flooding .
microbial flooding

   
-The thermal recovery methods are steam flooding, cyclic steam stimulation and in situ combustion.
-The gas miscible recovery methods are carbon dioxide flooding, cyclic carbon dioxide stimulation, nitrogen flooding and nitrogen-CO2 flooding.


-The chemical flooding methods are polymer flooding (including polymer gels), micellar-polymer flooding, and alkaline flooding.
-Microbial EOR methods include microbial flooding and cyclic microbial recovery.

Introduction to ECLIPSE 100

ECLIPSE 100 is a fully-implicit, three phase, three dimensional, general purpose black oil simulator with gas condensate option.


Program is written in FORTRAN77 and operate on any computer with an ANSI-standard FORTRAN77 compiler and with sufficient memory.



ECLIPSE 100 can be used to simulate 1, 2 or 3 phase systems. Two phase options (oil/water, oil/gas, gas/water) are solved as two component systems saving both computer storage and computer time. In addition to gas dissolving in oil (variable bubble point pressure or gas/oil ratio), ECLIPSE 100 may also be used to model oil vaporizing in gas (variable dew point pressure or oil/gas ratio).


Both corner-point and conventional block-center geometry options are available in ECLIPSE. Radial and Cartesian block-center options are available in 1, 2 or 3 dimensions. A 3D radial option completes the circle allowing flow to take place across the 0/360 degree interface.


How to start?

To run simulation you need an input file with all data
concerning reservoir and process of its exploitation.



Input data for ECLIPSE is prepared in free format using a keyword system. Any standard editor may be used to prepare the input file. Alternatively ECLIPSE Office may be used to prepare data interactively through panels, and submit runs.



The name of input file has to be in the following format: FILENAME.DATA
