Planning and execution of well interventions are paramount to achieving optimal performance after many years of production. Our multi-disciplinary technical […]
Waterflooded oil fields can offer additional opportunities to increase ultimate recovery. In-depth understanding of the project and the selection of […]
Complex oil and gas fields need innovative technological solutions to maximise productivity. In addition, highly volatile fluid conditions require accurate modelling techniques to evaluate reservoir behaviour under high GOR and predict well production for different scenarios. Hydraulic fractures have been evaluated for a full field model along with other completion designs and presented to the client as part of potential field development options.
A major oil field requires water injection support to maximise production. Completion designs & solutions for ESPs in high GOR wells of this field development have been analysed and proposed to the client
Sedimentological and stratigraphic studies provide priceless information on architecture, nature and heterogeneities of sedimentary geological objects (both in surface and subsurface).
Several challenges are faced in the development of a reservoir. The reservoir simulation model must accurately predict the past, current, and future performance of the field.
Carbon, Capture and Storage (CCS) is considered essential for reaching a sharp reduction of the global CO2 emissions. Capturing CO2, from e.g. point sources, and injecting it in the geological subsurface, permanently isolates the greenhouse gas from the atmosphere.
This study summarises the results of our first-order conceptual feasibility study. We investigated the concept of injecting and circulating CO2 for geothermal energy production from potential CO2 storage formations in Switzerland.
Multi-disciplinary projects involve a large amount of data of various nature that must be securely stored, quality checked and carefully organized to ensure confidentiality and high-quality analyses.
Reflection seismology is commonly recognized as one of the most powerful geophysical methods. Specific exploration targets for Geothermal, Petroleum, Mining or Nuclear Storage industries define unique processing workflow for every acquired seismic dataset.
Reflection seismology and seismic imaging today is one of the most powerful geophysical methods. It is successfully applied in Geothermal, Petroleum, Mining, and Nuclear Storage exploration.
Stochastic multimineral log analysis is a powerful tool for quantifying rock properties such as mineralogy, porosity, and water saturation in complex carbonate, siliclastic and shale sedimentary basins.
Innovative multi-disciplinary approach (combining bore-hole imagery, core data, 3D seismic and field production) have been applied to better characterize and represent karstic features.
The study we performed for the Geneva Geothermal project aims to locate and identify the geometries of the tectonic structures in the Geneva Basin and in the adjacent Jura fold-and-thrust belt.
In the global search for renewable and low-emission energies, there is a strong emphasis on geothermal potential and the accurate characterization of known resources.
Ad Terra Energy has been working closely with Nagra (the Swiss National Cooperative for the Disposal of Radioactive Waste) since 2019 to conduct geoscientific investigations in both shallow and deep boreholes to produce detailed analyses of the underground geological environment.
