The disclosure herein includes methods of preparing ceramic beads, useful as proppant materials, by mixing ceramic precursors, such as slag, fly ash, or aluminum dross, forming bead precursors from the mixture, and heating the bead precursors to drive a chemical reaction between the ceramic precursors to form the ceramic beads. The resultant ceramic beads may be generally spherical particles that are characterized by diameters of about 0.1 to 2 mm, a diametral strength of at least about 100 MPa, and a specific gravity of about 1.0 to 3.0. A coating process may optionally be used to increase a diametral strength of a proppant material. A sieving process may optionally be used to obtain a smaller range of sizes of proppant materials.

A system and method for producing hydrocarbons from a subsurface hydrocarbon-bearing formation. The system includes a production well, at least part of the production well located in a portion of the hydrocarbon-bearing formation. A heating well is also provided, at least part of the heating well located in a portion of the hydrocarbon-bearing formation; wherein the heating well includes a main well and a plurality of smaller bore lateral wells extending into the hydrocarbon-bearing formation. The smaller bore lateral wells improve heat distribution within the formation, and so fewer heating wells are required to achieve the same effect as using heating wells without smaller bore lateral wells.

A method for use in surveying a subsurface region beneath a body of water by detecting S waves propagating through the subsurface region. The method comprises using a first sensor configuration to detect mixed S and P waves on or in the subsurface region, using a second sensor configuration located on or in relatively close proximity to the subsurface region to detect P waves in the water, and using the P waves detected in the water to compensate the detected mixed S and P waves, and thereby attenuate the effects of P waves in the mixed S and P waves.

There is provided a method of initiating or accelerating the establishment of fluid communication between injection and production wells located in a formation, including injecting sufficient solvent into the wellbores of the wells that the solvent more than occupies the horizontal sections of the wells; pressurising the solvent column in the injection wellbore and optionally also production wellbore by the injection of gas such that the pressures of the horizontal section of the injection well and optionally the production well are greater than the formation fracture pressure; maintaining the pressure in the injection wellbore and optionally also the production wellbore; depressurising the injection wellbore and, if pressurized, the production wellbore, the differentials in pressure between the two resulting in backflow of a mixture of solvent and heavy hydrocarbons into the horizontal sections of the production well and/or injection well; and repeating the pressurisation and depressurisation steps for at least one more cycle to generate pressure swings, thus creating enhanced convection of solvent/solvent-heavy hydrocarbon in the porous media of the formation around the well and in the region between the two wells.

In order to unlock the full potential of Europes offshore resources, network infrastructure is urgently required, linking off-shore wind parks and on-shore grids in different countries. HVDC technology is envisaged but the deployment of meshed HVDC offshore grids is currently hindered by the high cost of converter technology, lack of experience with protection systems and fault clearance components and immature international regulations and financial instruments. PROMOTioN will overcome these barriers by development and demonstration of three key technologies, a regulatory and financial framework and an offshore grid deployment plan for 2020 and beyond. A first key technology is presented by Diode Rectifier offshore converter. This concept is ground breaking as it challenges the need for complex, bulky and expensive converters, reducing significantly investment and maintenance cost and increasing availability. A fully rated compact diode rectifier converter will be connected to an existing wind farm. The second key technology is an HVDC grid protection system which will be developed and demonstrated utilising multi-vendor methods within the full scale Multi-Terminal Test Environment. The multi-vendor approach will allow DC grid protection to become a plug-and-play solution. The third technology pathway will first time demonstrate performance of existing HVDC circuit breaker prototypes to provide confidence and demonstrate technology readiness of this crucial network component. The additional pathway will develop the international regulatory and financial framework, essential for funding, deployment and operation of meshed offshore HVDC grids. With 35 partners PROMOTioN is ambitious in its scope and advances crucial HVDC grid technologies from medium to high TRL. Consortium includes all major HVDC and wind turbine manufacturers, TSOs linked to the North Sea, offshore wind developers, leading academia and consulting companies.

Our goal with the DEEPEGS project is to demonstrate the feasibility of enhanced geothermal systems (EGS) for delivering energy from renewable resources in Europe. Testing of stimulating technologies for EGS in deep wells in different geologies, will deliver new innovative solutions and models for wider deployments of EGS reservoirs with sufficient permeability for delivering significant amounts of geothermal power across Europe. DEEPEGS will demonstrate advanced technologies in three geothermal reservoir types that provide all unique condition for demonstrating the applicability of this tool bag on different geological conditions. We will demonstrate EGS for widespread exploitation of high enthalpy heat (i) beneath existing hydrothermal field at Reykjanes (volcanic environment) with temperature up to 550C and (ii) very deep hydrothermal reservoirs at Valence (crystalline and sandstone) and Vistrenque (limestone) with temperatures up to 220C. Our consortium is industry driven with five energy companies that are capable of implementing the project goal through cross-fertilisation and sharing of knowledge. The companies are all highly experienced in energy production, and three of them are already delivering power to national grids from geothermal resources. The focus on business cases will demonstrate significant advances in bringing EGS derived energy (TRL6-7) routinely to market exploitation, and has potential to mobilise project outcomes to full market scales following the end of DEEPEGS project. We seek to understand social concerns about EGS deployments, and will address those concerns in a proactive manner, where the environment, health and safety issues are prioritised and awareness raised for social acceptance. We will through risk analysis and hazard mitigation plans ensure that relevant understanding of the risks and how they can be minimised and will be implemented as part of the RTD approaches, and as a core part of the business case development.

New concepts for high-temperature geothermal well technologies are strongly needed to accelerate the development of geothermal resources for power generation in Europe and worldwide in a cost effective and environmentally friendly way. The GeoWell project will address the major bottlenecks like high investment and maintenance costs by developing innovative materials and designs that are superior to the state of the art concepts. The lifetime of a well often determines the economic viability of a geothermal project. Therefore, keeping the geothermal system in operation for several decades is key to the economic success. The objective of GeoWell is to develop reliable, cost effective and environmentally safe well completion and monitoring technologies. This includes: - Reducing down time by optimised well design involving corrosion resistant materials. - Optimisation of cementing procedures that require less time for curing. - Compensate thermal strains between the casing and the well. - Provide a comprehensive database with selective ranking of materials to prevent corrosion, based on environmental conditions for liners, casings and wellhead equipment, up to very high temperatures. - To develop methods to increase the lifetime of the well by analysing the wellbore integrity using novel distributed fiber optic monitoring techniques. - To develop advanced risk analysis tools and risk management procedures for geothermal wells. The proposed work will significantly enhance the current technology position of constructing and operating a geothermal well. GeoWell aims to put Europe in the lead regarding development of deep geothermal energy. The consortium behind GeoWell constitutes a combination of experienced geothermal developers, leading academic institutions, major oil&gas research institutions and an SME. These have access to world-class research facilities including test wells for validation of innovative technologies and laboratories for material testing.
