This paper gives a comprehensive study of scaling risk evaluation from downhole to topside flowline in the absence...

..., Kumar, & Pandey, 2016 ). Encouraged by these positive results, operators are looking at applying the process in new fields even in the context of low oil prices and are evaluating its feasibility in more challenging reservoir conditions: high salinity, high hardness and high temperature. Most...

... Hydraulic fracturing fluids are pumped at high pressures to break down the rock and carry proppant inside the generated fractures. With the rise of exploration technologies, many potential wells are located in high-temperature formations. Polymers, crosslinkers, and other various additives...

... to a much higher viscosity. This will allow to sufficiently improve the mobility ratio. Preliminary results from lab-scale studies have indicated that along with reversibly adjustable viscosity property, SMA solutions are also tolerant to high temperatures and salt concentrations. Supramolecular solutions...

... Abstract The PG reservoir in Jidong Oilfield is at a depth of around 15,000 ft with an extremely high-temperature of about 300 °F. The average water cut has reached nearly 80%, but the oil recovery is less than 10% only after two years of water flooding process. It is of great importance...

... level; in that PV and YP decrease level is lower than 20% which is the half of the efficient KCL containing muds. The fluid loss is sufficiently controlled, less than 5 cc even at high temperatures, and lubricity effect provides us with a really acceptable Kf (friction of coefficient factor), under 0.2...

... Abstract Chemical flooding usually cannot achieve good oil displacement effectiveness in strong heterogeneity, high temperature and high salinity(SH/HT/HS) reservoir. Through a typical SH/HT/HS reservoir in Shengli Oilfileld, this paper builds a screening method to select the optimal chemical...

... also been integrated within a sand screen which utilizes the unique properties of ceramics to resist against erosion, corrosion and high temperatures in the downhole conditions. Ceramic properties and sand screen testings The unique properties of technical ceramics made from silicon carbide...

... saturation above the 100 ft. transition zone of 20-30% The reservoir is normally-pressured at 2200 psi, but has a high temperature gradient of 5.2 degF/110 ft., so the reservoir temperature can reach 325 degF This paper tells the story of fraccing the DC-15 oil development well, which transformed the well...

... Abstract When it comes to ultra-deep wells drilling, there are multiple difficulties to be considered: over-pull and blockage during tripping because of swelling of shale and clay, instability, and costly maintenance of traditional water-based drilling fluid in high temperature. In order...

... for extreme high temperature conditions. Geothermal, High Temperature and High Pressure, Steam Assisted Gravity Drainage (SAGD), Cyclic Steam Stimulation (CSS) (also known as Steam Flood) and Fire Flooding are all examples where the cement sheath can experience extreme high temperatures. This study...

... or the pore size distribution. The permeability increased after heating and the T2 distribution of each sample has changed. Minerals have been changed due to water evaporation and high temperature. It accounts for the change of T2 distribution. Comparing plots and images before and after heating, the heating...

... predict the HTHP rheological parameters. First, the rheological properties of a high density (2.04sg) oil-based drilling fluid at high temperature and pressure were measured. The experimental results indicate that the pressure effect on the rheological properties at ambient temperature was considerable...

..., that is, thermal conduction allows heat to sweep areas of the reservoir not contacted by steam. In this case, thermal expansion is an important recovery mechanism. Wettability Alteration and Interfacial Tension Decline under High Temperature For the low permeable light-oil reservoir in the paper...

... nature, better health, safety and environmental (HSE) profile, enzymes provide an excellent alternative to harsh chemical treatments in high temperature formations. However, their use has been limited to relatively low temperature applications due to their instability at elevated temperature values...

... Abstract Reservoirs in Tarim Basin, China west, were geologically formed in marine environment with high temperature (over 140) and high salinity (up to 25% TDS and 1% Ca 2+ + Mg 2 +). After 10 years of development by water flooding, unwanted water production become a big problem...

... Abstract The laboratory performance properties of the colloidal dispersion system are described in the proposed paper. This paper deals with the improvement and application of a new technology to EOR. This technology is applicable to high salinity, high temperature and severe heterogeneity...

... of the experiments is explained. In order to provide reliable experimental data, high pressure and high temperature experiments (up to 40 MPa and 500°C) are performed with consolidated reservoir cores and reservoir oils, at representative conditions of the air injection process in light oil reservoir.
