... the source by injecting epoxy into the annular space at depth, forming a 360-degree pressure barrier. The project can be broken down into three main sections. The paper and presentation will address each section with its specific challenges, learnings, and outcomes: Onshore Epoxy and Tool Preparation Each...

... Abstract Several researchers have demonstrated in laboratory experiments and field applications that reducing the concentration of salts and the content of multivalent cations in the injection water may increase oil recovery. This study evaluates the performance of low salinity water injection...

... then added to the model at the exact location indicated on the structure map. Simulations were conducted using varying injection rates, slug size and soak times for CSS, CCO 2 S and combined CSS and CCO 2 S to determine optimal EOR performance and production. The combination of CSS and CCO 2 S show...

... Abstract Foam has been extensively investigated as a method to improve the mobility control of non-condensable gases in the EOR context. Recently, there has been renewed interest in foam applied to steam injections. However, steam is a condensable gas and thus steam-foam requires special...

... water or polymer injection enhanced start-up process significantly. Infilling well pairs or wedge well, and sidetracking horizontal well or fishbone well effectively tapped the unswept remaining oil by steam. The other technologies further improved steam chamber conformance including non-condensable gas...

.... This passive vibrational energy stabilizes the original micelle structure in oil and prevents wax deposition and viscosity changes. A chemical solvent is injected to dissolve and remove wax deposits. In this study, both methods of wax treatment were applied on a waxy oil well in Trinidad, to determine which...

... was done. Finally, considerations for pilot projects with recommended facilities, required logistics and cost estimates were analyzed and the best options were recommended. Results, Observations, Conclusions Given the characteristics of the Southwest Soldado field, Water Alternate Gas (WAG) injection...

... Abstract This paper presents the application of multiple selectives injection zones within a high thickness singled bed heavy oil sand. The results were compared with a single zone completion in the same sand, establishing the differences in several aspects like recovery factor, vertical...

... the performance of the oil rate, cumulative steam-to-oil ratio (cSOR), steam depletion zone, greenhouse gas emission and some necessary parameters. The key component of the steam fracturing (dilation) is the ability to inject high temperature and pressure steam into the formation to fracture the reservoir rock...

... Abstract Enhanced Oil Recovery (EOR) has been utilized in Trinidad and Tobago for over 50 years. Most projects so far have focused on thermal as well as gas injection along with the more conventional waterfloods. In spite of that, recovery factors are still relatively low and the country's oil...

... reformation. This research studies the effect of injecting thermodynamic inhibitors during steam injection on overcoming the problem of hydrate reformation which in turn will increase hydrocarbon recovery significantly from hydrate reservoirs. The reservoir model was built based on data collected from...

.... Different scenarios were run and compared. The results showed that the gel system performed better in the injection well compared to the production well. In addition, the treatment was more efficient when performed simultaneously in injection and production wells. Placement technology was among...

... Abstract Cyclic water injection is an enhanced oil recovery method in heterogeneous reservoirs with zero additional cost and simple implementation procedure. It has been successfully applied in a number of oilfields in China, USA and Russia. However, although it is effective in conventional...

... Abstract During the last years the exploitation of heavy oil reservoirs has gained a great attraction, the application of techniques such as continuous steam injection has increased around the world. Although there are many successful projects, inherent problems such as the overriding effect...

... with successful results due to an efficient vertical and areal sweep achieved through selective injection. The successful in production increment also bring us a huge increment in produced water in a ratio of 1 BOPD to 6 BWPD. But, we notice that there where patterns with more than 90% of BSW in between...

.... The operator followed long-term strategic workover plans, but paraffin deposition still continued. Further investigation highlighted that the implementation of an optimal chemical injection program would be critical to realize maximum financial benefit from production of this maturing reservoir. The operator...

... Abstract Polymer flooding is a chemical EOR technique in which polymer is added to injection water, increasing its viscosity, decreasing water-oil mobility ratio and hence improving sweep efficiency. This recovery method create unique conditions that are absent in traditional water flooding...

... projects the question often arises as to whether it is better to start by injecting water or to go straight to polymer injection. Injecting water first provides a baseline for comparison with the polymer flood and in some cases allows an earlier start-up of the project due to the construction...

... Abstract Low-salinity waterflooding has been an emerging EOR/IOR technique in the recent times. LSW-alternating-CO 2 injection has been particularly strong in yielding higher oil recoveries in some cases. Limited simulation studies haven been performed to properly exhibit the interpretation...
