Workshop Overview

‘Enhanced Oil Recovery – Key to Productivity  ‘ is one of the critical areas in petroleum production technology. This is due to fast depletion of oil reserves than expected, all over the world. Almost all the oil-producing countries are facing this problem and many wells have been declared dry wells. In many cases, expected crude production could not be achieved due to the reduction in reservoir’s natural pressure; Lower crude to water ratio and excess gas to oil ratio. Many oil producing companies have drilled a number of wells than optimum, in an anxiety to increase crude production which has resulted in faster depletion of petroleum reserves than envisaged.  

Chief of drilling operations must know what is the optimum rate of production, to sustain continuity at plan rate and when should secondary recovery start and when should tertiary recovery start etc. Both secondary and tertiary recovery fall under Enhanced Oil Recover and the production cost will be comparatively higher than primary recovery case. Production plan must be based on this information. 

Enhanced Oil Recovery Decision models address this problem using quantitative techniques like operations Research and EORT modeling and well simulation models. 
 
The present workshop will elaborate typical oil production method starting from the exploration stage, primary recovery, secondary recover and tertiary recovery phases of productionIn Quantitative decision-making techniques, a number of models will be presented in the simplest form, which will enable participants to understand and solve the problem with ease.
