IntroductionThe primary source of energy is still fossil fuels which need to be managed properly. Energy consumption is the main motivation behind various hydrocarbon recovery techniques. In general, primary, and secondary techniques of production can result in 20-40% of conventional oil production in place (Nwidee et al. 2016, Thomas 2008, and Muggeridge et al. 2014). As a result, the residual oil will be extracted using various technologies known as Enhanced or Improved Oil Recovery (EOR, or IOR). EOR technologies are classified into three types: thermal, chemical, and gas/solvent injection. Because of the physics of porous media, the trapping and mobilization of crude oil can be difficult to grasp. The underlying physics includes factors, such as high interfacial tension, temperature, oil viscosity, capillary pressure, and complex rock-fluid and fluid-fluid interactions. Injecting chemicals into the reservoir will change the initial equilibrium state of the hydrocarbon fluids, potentially resulting in the mobilization of trapped oil.

“…Although ASP flooding seems promising in the laboratory as a tertiary recovery method, field experience has revealed several complicating features of the technology. Thus, it has been observed that the main problems while ASP flooding is related to operational arrays [12][13][14][15]. The scaling problem is the most common among ASP flood projects, and it creates the need to redesign surface facilities from ASP solution preparation units to production and processing units.…”

“…The main associated problem is the loss of production. Therefore, potential emulsification issues should be envisaged preliminary as it was done in the Bhagyam field having additional demulsifier injection wells near producers [12]. Also, Finol et al [13] have reported preliminary laboratory experiments on identifying cost-effective demulsifiers in the designing stage of the Al Khalata pilot test.…”

“…Furthermore, polymer flooding (PF) is often the most feasible chemical EOR technology. Especially, polymer flooding has prominence, where ASP/SP flooding is not profitable and causes serious on-site problems (scaling, uptime decrease, injectivity issue, hard-to-break emulsions) [12][13][14][15]. In addition, this paper describes the economic viability of ASP flooding based on some field case studies from the literature.…”

Polymer flooding is a promising and effective chemical Enhanced Oil Recovery (cEOR) technology. Polymer flooding is especially cost-effective, whereas other chemical flooding methods, such as Alkaline Surfactant Polymer (ASP), are not profitable and cause serious on-site problems (scaling, uptime decrease, injectivity is-sue, hard-breaking emulsions). Recent papers in the literature mention ~30 field polymer floods. Most of them reported technical success. Although, polymer flooding has been applied ~60 years, itstill requires fur-ther investigation to provide improvements. Thus, this paper describes important aspects and performances during for polymer flooding based on a review of recent projects, combined with the Kalamkas field experi-ence. A comprehensive literature review examines the applicability range in temperature, brine salinity, water source selection, oil properties, formation type, and permeability. Water source selection has an essential role during pilot/field project design and is one of the most responsible technical and economic success decisions. Polymer slug design has been extensively analyzed especially for the high viscosity oil fields, the selected oil/polymer viscosity ratio was usually much less than one. We placed significant emphasis on clarifying ob-served high polymer injectivities. We conducted feasibility studies of some reported ASP floods to clarify that this technology is not profitable at current oil prices. Also, we performed TAN analysis of three Kazakh-stan oil fields for screening of ASP flood.

Bhagyam is an onshore field in the Barmer basin, located in the state of Rajasthan in Western India. Fatehgarh Formation is the main producing unit, comprising of multi-storied fluvial sandstones. Reservoir quality is excellent with permeability in the range of 1 to 10 Darcy and porosity in the range of 25-30%. The crude is moderately viscous (15 – 500 cP) having a large variation with depth (15 cP – 50 cP from around 270 m TVDSS to 400 m TVDSS and then rising steeply to 500 cp at the OWC of 448m TVDSS). Lab studies on Bhagyam cores show that the reservoir is primarily oil wet in nature. Bhagyam Field was developed initially with edge water injection and with subsequent infill campaigns, prior to polymer flood development plan implementation, the Field was operating with 162 wells. Simple mobility ratio and fractional flow considerations indicate that improving the mobility ratio (water flood end-point mobility ratio is 30-100) in Bhagyam would substantially improve the sweep efficiency. Early EOR screening studies recommended chemical EOR (polymer and ASP flood) as the most suitable method for maximizing oil recovery. The lab studies further demonstrated good recovery potential for Polymer flood. Bhagyam's first Polymer flood field application started with testing in one injector which was later expanded to 8 wells. Extended polymer injection in these wells continued for four years. Observing a very encouraging field response, field scale polymer expansion plan was designed which included drilling of 28 new infill wells (17 P+ 11 I) and 24 producer-to-injector conversions. Modular skid-based polymer preparation units were installed to meet the injection requirements of the expansion plan. Infill producers were brought online in 2018 as per the plan but polymer injection was delayed due to various external factors. The production rate, however, was sustained without significant decline, aided by continuous polymer injection in initial 8 injectors, continuing water flood and good reservoir management practices. First polymer injection in field scale expansion started in Oct’20 and was quickly ramped up to the planned 80000 BPD in 4 months, supported by analyses of surveillance data, indicating very encouraging initial production response. Laboratory quality check program was designed to check quality of polymer during preparation and to ensure viscosity integrity till the well head. The paper discusses modular polymer preparation unit set-up and the additional installations designed to reduce pipeline vibrations during pumping of polymers., Experience gained while bringing online the polymer injection wells and the lab quality checks employed to ensure good polymer quality during preparation and pumping have also been discussed. The paper also discusses reservoir surveillance program adopted at the start of polymer injection like spinner survey, Pressure fall-off surveys and the stimulation activities that worked in improving the injectivity of polymer injectors. The paper further outlines the observations from the production response and the surveillance data collected to ensure good polymer flow in this multi-darcy reservoir.
