... Abstract Water control in mature heavy-oil reservoirs is a well-known challenge in the Oil & Gas industry. Due to the mobility ratio, water tends to flow much easier compared to oil, leading to premature water breakthrough which pushes water cut values to over 95% or more within weeks...

... a variety of wells. In this instance the gas molar compositions were similar so the only means to identify injection gas breakthrough in producing wells was by the CS-IRMS analysis technique. Complete physiochemical and water isotope ratio (δ 18 O and δ 2 H) analysis also show contrasting signatures between...

... pressures and improve recovery factors. API gravities vary between 14° and 24°. C&P vertical wells are drilled to access oil from several producing intervals. This inherently creates a challenging production environment, as injection water and/or formation gas can unpredictably breakthrough in any...

... Abstract Modification of CO 2 mobility to prevent premature breakthrough and poor sweep efficiency is a major step for improving oil recovery in CO 2 injection. Water-alternating-CO 2 , foam, and direct viscosification are the main proposed methods to limit CO 2 mobility and improve...

.... During the treatment, offsets were monitored for polymer breakthrough using flocculation tests. Any offending producer was shut in until resuming water injection. After treatment, water post-flush displaced the gel, and injector was shut in for 1-4 weeks (longer shut-in for lower polymer concentration...

... with no nanoparticles, and results from these floods are compared. In these experiments, breakthrough occurred 45% later with foamed CO 2 , and the final CO 2 saturation was also 45% greater than with the unfoamed CO 2 . The study shows how nanoparticles stabilize the CO 2 front. The results provide quantitative...
