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 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 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 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 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 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 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 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 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 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 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 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 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 The objective was to identify surfactants for Enhanced Oil Recovery by brine-oil interfacial tension reduction for a carbonate reservoir at ~ 25ºC and salinity of ~11,000ppm TDS; thus, Alkyl Propoxy Sulfates and their blends with sulfonates were evaluated to determine optimal salinity and ...
Abstract A field in the Central North Sea produces oil from a Forties type reservoir with seawater pressure support. The high salinity formation water contains up to 450mg/l barium, creating a significant scaling risk to the wells, all of which now show seawater breakthrough. The operator was required ...
Abstract With wet tree developments now outweighing dry tree developments in the North Sea, the challenge of accurate surveillance of scaling in wells is increasing. Often, multiple wells feed into manifolds which themselves feed into comingled systems. The need to differentiate multiple scale inhibitor ...
Abstract In many oilfields the relatively small number of high-cost, highly productive wells, coupled with a carbonate and or sulfate scaling tendency (upon waterflood breakthrough of injected seawater) requires effective scale management along with removal of near-wellbore damage in order to achieve ...
Abstract The learning from incidents and subsequent improvements made for the protection of people and integrity of offshore installations over the last 25 years has no doubt saved numerous lives. Places of refuge, blast protection, rapid isolation processes, offshore survival training and improved ...
Abstract The focus of this paper is innovation in oil sands recovery technology. Canada hosts the third largest reserves of petroleum in the world, mostly in heavy oil/oil sands reservoirs. The two commercial in situ recovery technologies, Cyclic Steam Stimulation and Steam-Assisted Gravity Drainage, ...
Conventional karyotypes and various genetic linkage maps have been established in sunflower (Helianthus annuus L., 2n = 34). However, the relationship between linkage groups and individual chromosomes of sunflower remains unknown and has considerable relevance for the sunflower research community. Recently, ...
