Non-seismic Geophysical Technologies and Non-Conventional Seismic

Update on where electromagnetics, in well fibre optic seismic, and more are adding value 0

Wednesday, October 11, 2017, London, The Geological Society

On October 11th we'll take a look at updates in non-seismic geophysics technology, looking in particular at electromagnetics, in-well fibre optic, and ways to integrate the data together and get value from it.

The event will include an afternoon workshop, free for all delegates, with updates on electromagnetic technology in oil and gas, sponsored and led by EMGS, one of the world's leading electromagnetics companies.

Agenda

9:30 Karl Jeffery - editor - Finding Petroleum Welcome & Introduction Talk Description. Karl Jeffery is editor and co-founder of Digital Energy Journal, and conference producer of Finding Petroleum. He is also publisher of Carbon Capture Journal and Tanker Operator, and co-founder of Digital Ship, a publishing and events company covering digital technology for the deep sea maritime industry. He has a BEng in chemical engineering from Nottingham University Finding Petroleum Finding Petroleum was established to help the oil and gas industry network, and stay up to date on the latest technological developments. It does this via hosting regular events and with an online social network of nearly 10,000 members.

9:40 Daniel Baltar - Global Exploration Advisor - EMGS Prediction of well results by using CSEM data Talk Description. Oil companies constantly seek to improve the exploration well performance by obtaining a more reliable prediction on prospect risk and volume. It is well documented that there often is a large mismatch between the predicted resource volume and the actual outcome. EMGS’ Exploration Solution, which integrates CSEM data into the exploration evaluation workflow, improves the prediction performance. Seismic data provides good structural and geometrical control. Therefore, we often see accurate evaluations on reservoir and trap chance factors. However, the charge and seal properties, which directly links to the presence of hydrocarbons in the reservoir, often has a large uncertainty if using seismic data only. Recoverable volume estimations are hardly ever correct, especially due to the high uncertainty related to the net reservoir area and thickness. CSEM data provides a resistivity image of the subsurface, where resistivity is sensitive to the reservoir hydrocarbon saturation. Integrating CSEM data will therefore improve the risk assessment on charge and seal, and limit the recoverable volume distribution uncertainty due to its natural sensitivity to net pay area and thickness. We will here demonstrate such results by comparing our pre-drill predictions and post well evaluations of wells drilled during 2017. Daniel Baltar is the Global Exploration Advisor for EMGS ASA. Is responsible for the integration of CSEM measurements in existing workflows and business models. Previously he founded Cycle Petroleum and was its exploration director from 2018 to 2021. He has had a lead role in the integration of EM data into the exploration workflow, starting with Pemex's campaign in the deep-water Gulf of Mexico, the largest CSEM acquisition in the history of the technology. Furthermore he has developed and published some of the key integration algorithms and workflows bridging exploration performance, play and prospect evaluation, and resistivity rock physics analysis. Also Daniel has worked as an explorationist and seismic QI in many different basins and depositional environments. Also, he has experience in digitalization, pore pressure prediction and shallow hazard analysis. He holds an MSc in Hydrocarbon Exploration and Production form ISE/Heriot-Watt and a degree in Physics. EMGS EMGS is a Norwegian, leading market share Geophysical company focused on the acquisition, processing, inversion and interpretation of 3D marine controlled source electro-magnetic (CSEM) data. To date that they have acquired over 850 commercial surveys worldwide and have over 110,000 km sq of 3D multi-client data covering many of the world's petroleum basins. The company has developed methods and tools to enable clients to integrate CSEM data into existing seismic and other geophysical datasets. When applied systematically across a CSEM sensitive portfolio. The new information provided by CSEM has the effect of polarizing existing evaluations, making CSEM a valuable tool in exploration venture evaluation. EMGS work in frontier regions and mature basins, from the Arctic to southeast Asia, and from offices across the world.

10:15 Garth Naldrett - Chief Product Officer - Silixa Fibre optic acoustic sensing (seismic) in wells Talk Description. Why many geophysicists now accept that quality of seismic data recorded on fibre optics in wells is equivalent to that of geophones The impact of fibre technology on conventional seismic Case studies of where fibre is used in carbon sequestrtation, microseismic and hydraulic projects – also inter-well pressure connectivity Silixa Silixa provides sensing solutions based on its pioneering distributed sensing technology. Silixa's intelligent Distributed Acoustic Sensor, iDAS, technology enables high quality digital recording of acoustic waves at every point along many kilometres of optical fibre cable up to frequency >100kHz with a wide dynamic range (>120dB). Silixa's distributed temperature sensor ULTIMA DTS offers the finest temperature of 0.01oC and spatial resolutions of 25cm over a wide operating temperature range.

11:20 Markus Krieger - Managing director - Terrasys Geophysics (15 min talk) Reducing exploration cost and subsurface uncertainty by integrating non seismic data Talk Description. - using a range of different data types can reduce model ambiguity - seismically focussed exploration strategies may be too short sighted in some cases - due to limited representation of the range of geoscientific model parameters, and high survey and processing costs - many exploration methods are used widely by the mineral exploration industry but not by the oil and gas industry Markus H. Krieger is Co-Founder and Managing Director of TERRASYS Geophysics and holds an MSc in Geophysics from Hamburg University. Due to his background in applied geophysics he moved the company to become a service provider for the oil & gas industry, focusing on integrated interpretation from a non-seismic perspective. Always striving to facilitate the most advanced solutions to TERRASYS’ clients, he kept good connections to the scientific community and established a strategic R&D culture at the company with a highly motivated team of geoscientists. Markus still sees a large demand for developing adequate interpretation tools for a multi-physics approach in order to address increasingly complex geological scenarios. He is always interested in discussing and implementing fresh ideas for a better understanding of the subsurface. Markus is member of AAPG, AGU, ASEG, BDG, DGG, DGMK, EAGE, EGU, HGS, IAMG, PESGB and SEG. Terrasys Geophysics Based in Hamburg and Houston as independent consultancy, TERRASYS Geophysics offers interpretation services to the international E&P industry, focusing on non-seismic technologies since 1993. Utilizing integrated workflows in close cooperation with our clients' experts, TERRASYS combines advanced 3D ground/marine/airborne gravity, magnetic, EM and full tensor gradient interpretations with geological and geophysical constraints, aiming to reduce subsurface uncertainty and exploration risk. Worldwide studies involved plays, prospects, and reservoirs with complex targets and tectonics; they showed how advanced multi-disciplinary modelling and joint inversion techniques help to achieve reliable geological solutions, such as precise salt geometries and constrained velocity models, e.g. for optimized prestack depth migrations.

11:45 Panel discussion with morning speakers - inspiring people to take more interest in non conventional geophysics Talk Description. How do we encourage the industry to take more interest in non conventional geophysics? Do we need a more creative and curious working atmosphere, and how can we get there? Is the answer to encourage people to take a more ‘portfolio’ approach to reservoirs, using all available data to get the best possible picture of how reservoirs are being produced?
