Polymer gels for water control: NMR and CT scan studies

As oil and gas reservoirs mature, larger volumes of water are produced. These large volumes of produced water need to be separated, processed, treated and re-injected into the reservoir. All of these processes impose extra costs to the hydrocarbon production. Water rates can increase until production from a certain field is no longer economical....

Two-phase reactive transport of an oil-soluble chemical: An NMR study

An oil-soluble chemical (OSC) is a chemical substance which is soluble and chemically inert in oil, but reacts with water to form a gel. Application of an OSC can be found in oil- and gas production. An increased water production, which usually occurs in mature oil fields, can be remedied by injecting the OSC in the near-wellbore area. The OSC...
