Abstract Foam has been employed as an Improved/Enhanced oil recovery (IOR/EOR) method to overcome gravity override and the channeling and fingering of the injected gas, which arises due to the low density and viscosity of the injected fluid combined with the rock heterogeneity. A major challenge; however, ...
Abstract KOC conducted its first 2D Offshore Seismic Acquisition Survey over the State of Kuwait Offshore covering some of the Environmental Sensitive & restricted areas to explore the hydrocarbon potentials in Offshore Areas. The potential environmental effects, risks and control measures were ...
Hard substrate associated with offshore oil and gas platforms can contribute to the productivity of marine ecosystems thereby generating local and regional economic benefits. These benefits form the basis for incorporating the platform into a rigs-to-reefs program when it is retired or selecting some ...
Abstract Four main areas of uncertainty can be described in polymer injection projects: Are we able to deliver the polymer solutions at the required quality to the wellhead? Are we able to inject polymers at the required quantity and quality? Are we producing sufficient incremental oil? Are we ...
Abstract We both evidence a new formulation for ultra-low IFT foams and a new coreflood set-up to demonstrate the efficiency of such a formulation in a model fractured reservoir. In fractured oil-wet carbonates reservoirs, recovery of oil from the matrix is limited by preferential flows in fractures, ...
Abstract An existing limitation of chelant-based fluids available for sandstone acidizing with hydrofluoric acid (HF) is the presence of sodium in the concentrate of the aminopolycarboxylate fluid, which is common in all chelating agents soluble below pH 3.5. The presence of sodium complicates stabilization ...
Abstract Drill-in fluids, also known as reservoir drilling fluids, are specifically designed to help minimize formation damage and facilitate wellbore cleanup. Typical water-based drill-in fluids use brines to achieve a desired fluid density and rely on acid-soluble solids, such as calcium carbonate, ...
This paper examines techniques necessary to fish coiled tubing (CT) with internal weld seams in a live well environment without back pressure valves (BPVs) using a hydraulic workover unit (HWO). The challenges of placing barriers in internal seamed CT verses using the slip and shear method is addressed. The ...
Abstract The goal of this work is to screen and evaluate laboratory mixtures of existing commercial, green sodium silicate chemicals that can be used for water management in carbonate naturally fractured (CNF) reservoirs. A thorough evaluation of a chemical for water management purposes requires the ...
Abstract Most multiple transverse fracture horizontal wells in shale gas formations remain in transient bilinear or linear flow for very long periods, typically several years. Some plays show very different behavior that has been attributed to pressure dependent permeability. Often, there are reported ...
The goal of this work is to develop a novel way of beneficially utilizing two main waste products from coal power-generation plants – carbon dioxide and fly ash – by generating fly ash nanoparticle-stabilized CO2 foam for CO2 EOR mobility control. First, as the grain size of fly ash is generally too ...
Abstract This paper examines the safety trends influencing and shaping the oil and gas industry. From rising local content requirements to increasing shortage of skilled workers, rise in unconventional Oil and Gas to an increasing number of frontier oil producing countries, the growing role of Operational ...
Abstract The Maari oil field, the first OMV operated offshore oil field development, has showcased OMV's impressive technical skills. Following the completion of a field re-development drilling campaign in August 2015, the well configuration currently consists of 10 producers and 1 water injector (with ...
Carbon dioxide (CO2) is a major greenhouse gas that is emitted in all activities. CO2 sequestration in coal enhances methane production from the coalbed (ECBM) in addition to storing CO2. CO2 can be stored in coalbeds in three ways: free gas within the pore space or fractures in the coal, adsorbed on ...
Abstract Since the industrial revolution in 18th century, people were always looking for more economical, more sustainable and – recently put into concerned about – more eco-friendly energy supply to fuel up the world economic growth. However the fact showed that the energy we consumed even became ...
Abstract Dimethyl Ether Enhanced Waterflood (DEW) is a novel and promising solvent-based EOR technology developed by Shell. Dimethyl Ether (DME) is a widely-used industrial chemical which is applied as a water soluble solvent for EOR applications to enhance a conventional waterflood. Once the DME-brine ...
Abstract Polymer flooding is a well-established chemical enhanced oil recovery (EOR) technique. However, its application to High-Temperature and High-Salinity (HTHS) carbonate reservoirs remains a challenging task due to the unavailability of polymers that can withstand the harsh conditions. Identifying ...
Abstract Condensation, vaporization and volumetric changes are well-studied phenomena that create differences between the properties of oil at reservoir and surface condition. But similar changes in effluent brine properties have not received the same attention. This study attempts to analyze variations ...
Abstract Mega oil and gas projects have become more frequent as scale has increased and as resources in increasingly remote locations are produced. Despite the harsh operating environments, the size and complexity of these projects are unprecedented. Contractors must; and are still expected to deliver ...
Abstract Smart waterflooding (SWF), an emerging EOR technique, was first investigated in sandstone reservoirs. However in recent years, the effect of smart water on carbonate reservoirs has gained wide interest. Despite the increasing number of research and publications in this area, the mechanism ...
