This book was released on 2018 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The lack of a single reasonable general mechanism to describe how low-salinity waterflooding can improve oil recovery in both laboratory and field pilot projects has increased the interests of many researchers and stakeholders. There has not been observed the relationship of formation brine salinity and injected brine salinity to see how much salinity is reduced to produce the maximum enhanced oil recovery by LSWF. There is no guidance in what EOR stage the LSWF is best implemented. This work collects data from various published literature to develop a comprehensive data set regarding low-salinity waterflooding in sandstone reservoirs. The LSWF mechanisms are discussed to gain better understanding of the LSWF effect on oil recovery in sandstone reservoirs. The data set consists of parameters from coreflooding experiments that involved core samples, crude oil, and brines from different places. Histograms and box plots are used to visualize various kinds of data, and cross plots and charts are used to analyze the relationship between the important parameters and oil recovery. This study revealed the complexity of LSWF mechanisms and the corresponding parameters in the COBR system that associate with this process. The effects of rock porosity and permeability, total clay content, core aging temperature, COBR wettability, initial water saturation, oil base/acid ratio, asphaltenes content, formation and injected brine salinity and composition on the enhanced oil recovery are discussed in both secondary and tertiary LSWF modes. The applicability of parameters affecting the LSWF process are summarized. It is also observed the relationship between formation brine salinity and how much injected brine salinity was reduced or diluted to produce the maximum incremental secondary and additional tertiary recovery. Finally, in comparison to the conventional waterflooding, the final recovery from all of the LSWF stages are higher than the one of the conventional waterflooding, and the secondary+tertiary EOR stage produces the highest final recovery"--Abstract, page iii.

Available in PDF, EPUB and Kindle. Book excerpt: The overall objectives of this work are: (1) to investigate the importance of various qualities and quantities of data on the optimization of water flooding performance; and (2) to study the application of newly developed, geostatistical techniques to analyze available production data to predict future prospects of infill drilling. Specifically, to satisfy our first objective, we will study the feasibility of applying fractal geometry concepts to characterize individual formations; develop a three-dimensional conditional simulation program to define reservoir properties at various scales; establish a method to integrate the data collected at various scales including the well test and the core data; and to investigate the utility of outcrop data in describing subsurface reservoir details. To satisfy the second objective, we will investigate various techniques to utilize the production data, including initial potential and the production decline, in proposing a possible location for a future infill well. The techniques investigated will include geostatistical and time-series analyses. The study will be restricted to Pennsylvanian sandstone reservoirs commonly found in Oklahoma. 2 refs.
Book Synopsis Low Salinity Water Flooding Application on Different Reservoir Rock Types by : mohamed magdy
Download or read book Low Salinity Water Flooding Application on Different Reservoir Rock Types written by mohamed magdy and published by محمد مجدي. This book was released on with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface chemistry has a great effect in enhancing oil recovery. For oil-wet sandstone reservoirs, low salinity waterflooding (LSWF) is effective as it can alter rock wettability and reduce the oil/water interfacial tension. LSWF application is related to rock’s clay content and type. Clay hydrocarbon bonding can be formed through many mechanisms such as van deer waals forces and ionic bridge. LSWF effect is to weaken these bonds through two main mechanisms, Double Layer Expansion (DLE) and Multicomponent Ionic Exchange (MIE). Two fields (S and D), in Egypt’s Western Desert, have depleted strongly oil-wet reservoirs with similar rock and fluid properties. Field (S) is flooded by low salinity water (LSW), while Field (D) is flooded by high salinity water (HSW). Fortunately, the water source for Field (S) flooding is a LSW zone, which has a salinity +/- 5000 ppm as total dissolved solids (TDS). The formation water salinity was +/- 25,000 ppm as TDS. Field (S) lab experiments showed good compatibility between injected LSW, formation water and rock minerals. XRD and SEM indicate calcareous cementation with detrital clays content around 5%. Kaolinite is the common clay type, which has a low cation exchange capacity. For Field (S), the estimated ultimate recovery (EUR) is 46%, while EUR for Field (D) is 39%. One of the main causes of this increase in Field (S) is LSWF application.

Book Synopsis Novel Insights Into Low Salinity Water Flooding Enhanced Oil Recovery in Sandstone Reservoirs by : Hasan N. Al-Saedi

This book was released on 2019 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Ever growing global energy demand and the natural decline in oil production from mature oil fields have been the main incentives to search for methods to increase recovery efficiency for several decades. Water flooding is extensively applied worldwide to improve oil recovery. The recent drop in oil prices has turned the oil industry to the cheapest improved oil recovery (IOR) techniques, such as low salinity (LS) waterflooding. Also, the reduction in reservoir energy and the friendly environmental aspects of low salinity water flooding (LSWF) provide additional incentives for its use. That LS water requires decreasing only the active divalent cations such as Ca2+, Mg2+ and water salinity makes LS water flooding a relatively simple and low expense IOR technique. The water chemistry significantly impacts the oil recovery factor. Wettability is one of the major parameters that control the efficiency of water flooding. The primary mechanism for increased oil recovery during LSWF in both sandstone and carbonate reservoirs is wettability alteration of the rock surface from oil-wet to water-wet. LS water imbibed into the low water-wet zones, the water wetness of the rock increased after injecting LS water, and in turn, microscopic sweep efficiency enhanced too. The mechanism behind LS water flooding has been extensively investigated in the literature but it still a topic of debate. The objective of this research is to solve the controversy and show the following: (1) Water chemistry weather partially or strongly determines the dominant wettability alteration mode. (2) The role of divalent cations in the formation water and in the injected water. (3) Clay's role for incremental recovery. This research work seeks to quantify the effects of mineral composition and water chemistry on water-rock interactions and wettability alteration"--Abstract, page
