... differential pressure for 30 minutes. The silane coating over the silica NPs was confirmed with the shifting in the peaks of the FTIR (Fourier Transform Infrared) spectra of the sample. Both the plastic viscosity (PV) and the apparent viscosity (AV) of the drilling fluid were found to be increasing with silane...

... Abstract Oil reserves with oil viscosity above 150 mPa·s account for a large proportion of the Bohai Oilfield. However, due to the low mobility of heavy oil, and low sweep efficiency of injected fluid, the recovery factor of heavy oil is always low. A new amphiphilic polymer (activator), which...

... Abstract Cation exchange occurs when water with a different salinity as the connate brine is injected in a reservoir. During polymer flooding operations, the potential release of divalent cations by the rock can have a detrimental impact on the in-situ viscosity in the polymer bank...

... to reservoir conditions. In a recent study Beteta et al. , compared the performances and results obtained with waterflooding, polymer flooding in secondary mode and polymer flooding in tertiary mode. In this study the crude-oil viscosity was 84 cP at 31°C. The study was conducted in Bentheimer outcrops...

... of residual oil on the foam generation and displacement efficiency was also investigated. Steady-state CO 2 injections revealed differences in foam generation, strength and stability in sandstone compared to carbonate based on the calculated apparent viscosities. Results showed that the strongest foam...

... In LSSC sections, it is still difficult to make artificial fracture break through the upper and lower layers by only use gelled acid even if the acid injection rate is greatly increased. A high viscosity fluid was introduced in acid stimulation treatments could make artificial fracture vertical...

.... To maximize these parameters, it is imperative to include a fluid diversion strategy in the treatment design. The use of high viscosity fluids and solid particles is well addressed in the literature as effective diversion methodologies. In this study, the benefits of a dual diversion system composed of solid...

... water saturation. In the second scenario, heavy oil was identified primarily from the presence of high apparent bound fluid and secondarily by a porosity deficit, and oil viscosity was computed. The high-angle well intersected the same carbonate reservoir layer multiple times. The NMR measurement...

... The viscosity of surface crude oil in Bohai × Oilfield exceeds 10000mPa·s, and there is basically no production capacity under the original formation temperature, so steam huff and puff development is required [ 1 - 3 ]. For the first round of steam huff and puff well, due to the sufficient...

... Abstract Field A is an onshore oil field in Thailand. This area contains biodegraded medium-heavy crude reservoir; 19°API oil gravity and 144 cp viscosity. Therefore, the field suffers from a low recovery factor due to high crude viscosity. On one hand, bacteria have exerted an adverse effect...

... Abstract New viscosity model named "Faisal-Viscosity model" was developed to address the large gap in the current rules and models in giving accurate predictions on the behaviour of bitumen-solvent mixtures. The Faisal's developed viscosity model is successfully able to give a more accurate...

... Abstract The reservoir of Daqing Heidimiao Oilfield (permeability 1736×10 −3 μm 2 ) contains heavy oil, with the average viscosity of 3306 mPa•s. It is developed by steam flooding and steam huff and puff, however, the recovery rate is only 14.6%. Therefore, the multi-component thermal fluid...

... Gas density were 150 kg/m 3 while oil and water viscosity were measured 1 cP and 0.48 cP respectively. Tests were performed with pressurized air at 130 bar which gives a density equal to 150 kg/m 3. The gas density is equivalent to hydrocarbon gas density at reservoir conditions. Abstract...
