Relative strength in oil prices, and sentiment that future supplies may be limited, have led some operating companies to explore in frontier areas that have proven, historically, to be highly productive. Some of these areas have seen little exploration activity for several decades for varied reasons, such as difficulty of access or governmental restrictions.
In this, the second part of a three-part article, we will discuss renewables (wind turbines and solar). We will look at price and Energy Returned on Investment (EROI) to compare sources of energy. We will also look at OPEC, at the lack of investment (which is causing the overall supply of energy to decrease), and at what is happening in oil and gas, including inflation and the possibility of a super cycle due to the lack of investment.
Carbon capture and storage (CCS) in geological formations is becoming a key technology for the permanent reduction of CO2 emissions in the atmosphere. Pilot-scale projects with small volumes of injected CO2 are important, as they provide well controlled conditions that enable testing, validation, and quantification of these monitoring technologies.
The job of a petroleum geoscientist is rapidly transforming into a role that requires proficiency with statistical concepts and data management. The goal of this primer is to provide the reader, through words, basic examples and images, an understanding of some of the basic principles behind the semivariogram/variogram, a statistical tool, that geoscientists can use to understand how their spatial data is changing over distance.
This is the second part of a two-part paper. This part of the paper explores some of the most recent advances in using seismic data for oil sands reservoirs. These are Time-lapse (4D) Inversion for SAGD; Predicting where Bitumen has been Liquified using PS-4D Seismic Data; 4D Time-Lapse Full Waveform Inversion for the SAGD Steam Chamber Imaging; 3D DAS FWI for the SAGD Steam Chamber Imaging; The role of Geophysics in Emission Reductions; Conclusions.
Our world has changed, and with it, there will be changes on what we publish. There will be tough topics you may not agree with, but others may. There are certain things about climate change that are now becoming accepted scientific theories, as with evolution or plate tectonics in the past. We need to come to terms with the fact that most of our investors and oil and gas operators want to lower emissions.
In this article, we will explore the basics of the well tie to seismic, starting with some basic seismic acquisition and processing concepts, definition and type of wavelets and a case study that will show the impact of using a wrong estimation of the time-depth relationship (obtained from the well tie process) in future workflows such as seismic inversion.
This paper is dedicated to Dr. Larry Lines (1949-2019), who was involved with seismic imaging and inversion, reservoir characterization, conventional oil and gas exploration, geophysical studies of heavy oil, oil sands, and monitoring effectiveness of steam assisted gravity drainage (SAGD), and who mentored us all.
Aeromagnetic surveys provide important information on geologic features and enable low-cost regional coverage. For these reasons, magnetic maps often serve as primary regional information on the resource potential in large areas.
Wes Rabey is someone we owe a lot to in the Canadian Geophysical community. This memorial is not a list of events he did but chronicles the impact he had on our industry. This is also a reflection on the history of our industry, especially regarding seismic brokerage.
