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.

Arbuzovskoye Well A-216 - Deviated Production Well: Water cut has increased significantly since initial production, Water influx coming from below the oil water contact, Workover options to plug off water also under review, Other South Arbuzovskoye wells unaffected.
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.
Since the bore was under water and between islands, salt water influx was a problem.
Diagnostic logging will be undertaken early in the programme to determine the selection of the most appropriate option to remedy the water influx into the well; and
We analysed two scenarios of water influx, taking into account the completionA of desalination plants and increased demand for consumption (compared to 2007)A and we found the system can now meet the water needs with continuous waterA supply"
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).
If we are successful with the fresh water influx programs they will lose the brown shrimp season entirely.
Firstly, we increased the water influx estimates by 7% to account for the degree to which the HTO technique underestimates dietary water consumption by Emperor Penguins (an average of values in Robertson and Newgrain 1992, Kirkwood and Robertson 1997).
The warm water influx displaces nutrient-loaded cooler waters and ultimately reduces the fish populations that the animals prey on, she suggests.
Empire considers that the high level of water influx was due to a combination of the location of the well close to the edge of the structure, poor well integrity and a less than optimal completion of the well.
The initial flow tests were measured at rates of 380 thousand cubic feet of gas per day (mcfd) however the well has been flowing into the gas sales pipeline at an average of ~220 mcfd due to water influx and pipeline pressure constraints.
