  water drive
Modeling of a water drive development scheme for an oil field with intrawell oil-water separation is studied.
      
The results show that fines migration in an oil formation can accelerate the development of heterogeneity of the reservoir rock, and has an obvious influence on production performance, i.e., water drive front, water-cut trends, and oil recovery.
      
Consider the water drive production system shown in Figure 2, which depicts an injector-producer configuration in a single-layer reservoir.
      
Injection has commenced in d-41-L, d-30-K and d-40-K to augment the natural water drive.
      
Last month's World Water Forum in the Japanese city of Kyoto had failed to advance the clean water drive, Prodi said.

  water flooding
Analysis of the contribution of the interlayer flows to the water flooding of low-permeability formation intervals calls into question the practicability of blocking high-permeability inclusions in the neighborhood of pumping wells.
      
Possibility of the development of a high-viscous oil reservoir by water flooding
      
Tidal water flooding mud flats are enriched in manganese, originating from upward migration of reduced species and further adsorption onto suspended particles under oxic conditions.
      
Hot water flooding of oil-bearing beds under conditions of mutual solubility of water and crude
      
In this paper, PHREEQM was used for the simulation of water-rock interaction under water flooding in the Renqiu Oilfield.

  waterflooding
The Fang-48 fault block oil reservoir is an extremely low permeability reservoir, and it is difficult to produce such a reservoir by waterflooding.
      
The threshold pressure gradient for gas injection is less than that for waterflooding, and the recovery by gas drive is higher than waterflooding.
      
In this paper, the results obtained from the microscopic research on the mechanisms of oil displacement by alkaline waterflooding are presented.
      
The types and flow behavior of emulsions formed during the oil displacement by alkaline waterflooding have been systematically studied, including the law of emulsification, flow state and oil bank formation etc.
      
Thus the more precise description of the mechanisms of oil displacement by alkaline waterflooding and its controlling factors are given.

  waterflood
It can be reasonably expected that the mine will be in such an excellent condition that no water hazard during waterflood terms will occur and full water supply during dry seasons will be guaranteed.
      
Potential ionospheric impacts on the Prudhoe Bay Alaska microgravity Waterflood Monitoring Survey
      
A waterflood simulation shows that retaining a single realization would yield, in average, larger errors in production forecasts (water cuts and recovered oil) than the single postprocessed facies map.
      
Characterization of Waterflood Saturation Profile Histories by the 'Complete' Capillary Number
      
A simple capillary model of free spontaneous imbibition and waterflood is introduced and used to interpret the 'complete' capillary number CA for immiscible displacement in porous media.

In this study, the Water saturations in a tWo-dimentional physical modelof oil reservoirs Were monitored With 3 cm Wavelength, and families of sharpeurves of both Waterflood and oilflood fronts Were obtained, which consistedwith Buckly-Leverett's theoritical curves; the correlations befWeen micro-Wave signal attenuatons and the Water saturation Sw, porosity φ,and thick-ness H of the model were derived and proved.Through experiments the corre-lative curves of received microWave signals Vg (or Ig) vs.S_W, φ and...

In this study, the Water saturations in a tWo-dimentional physical modelof oil reservoirs Were monitored With 3 cm Wavelength, and families of sharpeurves of both Waterflood and oilflood fronts Were obtained, which consistedwith Buckly-Leverett's theoritical curves; the correlations befWeen micro-Wave signal attenuatons and the Water saturation Sw, porosity φ,and thick-ness H of the model were derived and proved.Through experiments the corre-lative curves of received microWave signals Vg (or Ig) vs.S_W, φ and H havebeen constructed. Then the Water-saturationa nd porosity distributions of areservoir physical model with thickness less than 5cm can be determinedby means of these eurves. This technique, as far as its resolvng power,measurement accuracy, and applicability are concerned, is superior to thatof dissection, resistivity, capacity, x-ray and radioistope tracing, andpvovides a rapid, accurate and easy method for observing the change ofWaterflood fronts, studying oil recovery mechanism and residue oil distributions, searching for the optimum Waterflooding and pro ducing programs(the most reasonable Wellpattern and the best technics for sWeeping oil),and enhancing oil recovery.

The development of the massive carbonate reservoir with bottom water in the Wumishan Formation in the Renqiu oil field reveals that for the successful develo- pment of an oil field of this type,it is imperative to study the mechanism of dis- placement of oil by water together with the rule of bottom water movement on the basis of oil field geology. Combining theory with practice and summarizing the data of oil field develop- ment and the results of simulation tests,the author examines the dynamice of w- ater drive in carbonate reservoirs with dual porous media as well as the rule of bottom water movement and proposes a number of measures for tackling some of the basic problems relating to the improvement of oil field development.
