Water flooding oil recovery ppt
Waterflooding is the use of water injection to increase the production from oil reservoirs. Use of water to increase oil production is known as "secondary recovery" and typically follows "primary production," which uses the reservoir’s natural energy (fluid and rock expansion, solution-gas drive, gravity drainage, and aquifer influx) to produce oil. XII. OLD OIL FIELD WATERPLOOD OPERATIONS AND ENHANCED OIL RECOVERY POTENTIAL A. INTRODUCTION Substantial emphasis has been placed on secondary and enhanced oil recovery techniques in recent years. Research in enhanced oil recovery advanced because of higher exploration costs, increased demand for petroleum • It is the injection of water into a wellbore to push, or “drive” oil to another well where it can be produced • Recognized enhanced oil recovery technique since early 1900’s • Some oil reservoirs have natural water influx, which increases oil production – Called “water drive” reservoirs Polymer Flooding: Waterfloods can also be improved by polymer flooding. Addition of polymer makes the water more viscous so that oil is produced faster. Obviously, this is not an good idea in a low permeability reservoir or one with a high clay content that can adsorb the polymer. DK - 67 - Improving Waterfloods to display oil recovery in the same format as laboratory core-flood results. Recovery from fields using lower salinity injec-tion water was greater than that using higher salinity injection water—matching recovery trends for laboratory and single-well tests. Introduction Almost without exception, at the start of a waterflood, water Oil Recovery Techniques • Primary Depletion • Water Flooding • Water Drive/Pattern Injection • Low Salinity Waterflood (BP) • Smart Waterflood (Armaco) • Ion Management Waterflood (Exxon) • Low Tension/Low Salinity Waterflood (The U. of Bergen, Norway) • Microbial EOR • Immiscible Gas Injection • Nitrogen • Flue gas • Air injection • CO
Oil recovery from hydrocarbon underground reservoirs is the ultimate goal of the flooding, as the field has been under water and gas injection for a long time.

Recovery mechanisms Primary oil recovery Describes the production of hydrocarbons under the natural driving mechanisms present in the reservoir without supplementary help from injected fluids such as gas or water.. Recovery mechanisms Secondary oil recovery Refers to the additional recovery that results from the conventional methods of water injection and immiscible gas injection.

Many different techniques have been developed for this purpose such as steam flooding [2–6], polymer flooding [2,7–13], and gas injection [2,14,15], among others. • It is the injection of water into a wellbore to push, or “drive” oil to another well where it can be produced • Recognized enhanced oil recovery technique since early 1900’s • Some oil reservoirs have natural water influx, which increases oil production – Called “water drive” reservoirs

The terms primary oil recovery, secondary oil recovery, and tertiary (enhanced) oil recovery are traditionally used to describe hydrocarbons recovered according to the method of production or the time at which they are obtained. Primary oil recovery flood front at water breakthru (436.4 days) (Eq. 7) oil-water interface Figure 5 The flood front will eventually reach the producing well at which time water breakthrough will occur. Note that the value of the water saturation in the water-invaded portion of the reservoir at the time the water breaks through to the producing well will be about 70% Primary, secondary, and tertiary oil recovery (using pressure, water, and CO2).
