Abstract During the life of a producing oil field several production stages are encountered. Initially, when the field is launched to production, oil flows naturally to the surface due to existing reservoir pressure in the primary phase. As reservoir pressure drops, water is typically injected to boost ...
Abstract Scale deposition is one of the most serious oilfield problems when two incompatible waters interact chemically and precipitate minerals. Typical examples are sea water, with high concentration of sulfate ions and formation waters with high concentrations of calcium, barium, and strontium ions. ...
Abstract Low-salinity water flooding LoSalTM has been used to improve oil recovery for many decades. Historically, the physical mechanism behind this improvement in oil recovery was attributed to the pressure maintenance and displacement of oil by injected water. Recently, evidence from laboratory ...
Abstract Application of dendrimers and dendritic polymers in oil and gas field fluid formulation can revolutionise the fluid properties due to the unique physical, chemical and biological characteristics of these materials. The ability to synthesize tailor made dendrimer products with desirable functional ...
Abstract Conventional lubricant products composed of different surfactant materials are required in water-based mud for drilling highly deviated and horizontal pay zone sections due to their lubricity associated with torque reduction and better penetration rate. Drill-in fluid (DIF) filtrate-induced ...
Abstract The world is becoming flatter through global integration and ‘smarter' through interconnected communication and commerce. For oil and gas organizations this means finding ways to launch business ventures in new regions. While Afghanistan is a high risk zone with negative trade balance, ...
Abstract This paper examines the potential risk of using controlled implosions as a new technique to securely seal an offshore leaking oil pipe. Massive amount of toxins and radioactive waste are produced by offshore oil leaks. These leaks can have negative impact on marine life and can threaten the ...
Abstract Traditional feasibility studies for remediation projects consider factors including cost, implementation risks, reliability and environmental protection. However, traditional studies do not address corporate and stakeholder desires for more sustainable business practices. Approaches are needed ...
Abstract Wetland restoration is essential in addressing wetland loss along the coasts of Southern Louisiana. Wetland restoration techniques, such as planting mangroves, provide a wealth of benefits such as storm surge reduction, fish and wildlife habitat, carbon sequestration, recreation, job creation, ...
Abstract With the expanding global workforce, companies are faced with several barriers to any standardization or centralization plans. Challenges like language difference, local differences, interdependencies, size and maturity and mode of operation can create strong barriers to an effective rollout ...
Abstract Accurate environmental impact assessment and reliable monitoring of the ecosystems exposed to drilling and produced water discharges are key for offshore Exploration and Production (E&P) industry. The ability to determine and manage effects discharges are having on the surrounding environment ...
Abstract A new and proprietary in-situ recovery process for bitumen enhanced oil recovery is described herein (International PCT Patent Application No. PCT/CA2012/000652). SAGDOX (Steam Assisted Gravity Drainage (SAGD) with the addition of OXygen injection) is a reservoir recovery process that uses ...
Abstract Chemical flooding for Western Canadian heavy oil reservoirs has gained popularity in recent years because of its satisfactory recovery efficiency and low facility cost. Formation brines in most of these reservoirs have extremely high salinity and hardness. Addition of alkali is prone to causing ...
Abstract The deposition and accumulation of inorganic scales is a major concern for oil and gas producing companies worldwide. This concern typically stems from two main factors: the strong possibility of total production loss due to scale plugging of production conduits, and the significant impact ...
Abstract Low-salinity water flooding LoSal™ has been used to improve oil recovery for many decades. Historically, the physical mechanism behind this improvement in oil recovery was attributed to the pressure maintenance and displacement of oil by injected water. Recently, evidence from laboratory and ...
Abstract This paper discusses a structured combination of procedures used to investigate polymers for EOR application with the focus on performance, compatibility with production chemicals and phase behaviour. This approach allows for early identification of risks and points to further work necessary ...
Abstract Chemical injection in enhanced oil recovery (EOR) projects is a complex process because it involves multiple chemicals with complex fluids. Costs for even a small-scale pilot test could be up in the millions of US dollars (USD) and large-scale field-wide expansion would be in the 100s of millions ...
Abstract Reservoirs containing very high total dissolved solids and high hardness make the design of a surfactant polymer (SP) flood extremely difficult because surfactant tends to precipitate and separate under these conditions. Beside divalent ions, Ca2+, Mg2+, presence of iron in the brine can be ...
Abstract: Factors confronting the application of surfactant flood in high temperature, high salinity carbonate reservoirs include: high concentration of divalent ions in the formation brine, the stability of the surfactant in high thermal environment, surfactant adsorption on carbonate rock fabrics ...
Abstract Many studies have been performed to identify chemical additives that will aid shale stability in large volume slick water fracturing treatments. Most of the targeted shale formations have a very low permeability, do not experience conventional leakoff and do not contain high amounts of swelling ...
