METHOD FOR LIQUID AND/OR GAS RECOVERY FROM RESERVOIR Russian patent published in 2006 - IPC E21B43/00 

FIELD: methods or apparatus for obtaining oil, gas, water, soluble or meltable materials or a slurry of minerals from wells.

SUBSTANCE: method involves determining initial reservoir parameters by carrying out at least one geological modeling stage; analyzing obtained reservoir parameters to generate initial reservoir development program; determining number of wells to be drilled and well pattern on the base of above reservoir development program; drilling wells in predetermined locations; carrying out the first measurements in reservoir with the use of re-entry data acquisition system and/or constant pressure gages and/or deposit estimation detectors installed inside and outside cased wells to obtain highly-intensive monitoring data to perform current control of working reservoir characteristics; carrying out the second reservoir measurements to obtain low-intensive monitoring data to provide additional control of working reservoir characteristics, wherein the second measurements are performed by rear (random) time intervals metering; summing high-intensive and low-intensive monitoring data and making a decision about initial reservoir development program improvement on the base of data summing; repeating reservoir parameter determination, well number and pattern determination, the first measurement, the second measurement and data summing operations after improved reservoir development program generation up to receiving results, which indicate reservoir depletion.

EFFECT: possibility to optimize liquid and/or gas recovery from reservoir.
