water influx

water influx

[′wȯd·ər ′in‚fləks]
(petroleum engineering)
The incursion of water (natural or injected) into oil- or gas-bearing formations.
One of the mechanisms of oil production in which the water movement (drive) displaces and moves the reservoir fluids toward the well borehole.

Remarkably, this mechanism resembles that which occurs in marine teleost oocytes undergoing meiotic maturation, where water influx, driven by an increased osmolyte pool of free amino acids resulting from yolk proteolysis, is mediated by a teleost-specific Aqpl-like channel (Fabra et al., 2005.
The HVL systems within Mauddud and Nahr Umr Reservoirs are now being effectively applied in other regions of the reservoirs with natural water influx and provide a drag-oil effect that also encourages oil out of the rock pores.

Freshwater teleosts must balance the improvement of O2 diffusion at the gills with the osmoregulatory disadvantage that result from the ion loss and water influx increases (Perry and McDonald, 1993).
Drilling encountered high pressure, water influx and a weak Fm fracture gradient below 3,500m.
The World Bank noted a "clear evidence" that production of oil and condensate was declining, adding: "Such declines may be permanent, because the producing reservoirs are experiencing drop in pressure and water influx (see OMT & Gas Market Trends of next week).
