Geophysicist

• Dec 2021 - Present

Ph.D. Candidate in Geophysics/Petrophysics Machine Learning

• Sep 2018 - May 2022

Ph.D. Candidate in BRU 21 Research Program within the Exploration Efficiency area at the Department of Geosciences and Petroleum at NTNU. My project is in collaboration with AkerBP ASA, and it is mainly focus on proposing a novel well log database structure to provide easy access to all data and a more comprehensive organization of the well information via Python programming. In addition, I am working on developing several tools to perform automatic depth matching of LWD (logging while drilling) and EWL (Electrical Wireline logging) logs reducing user intervention and turnaround times by implementing different algorithms like cross-correlation, Dynamic time warping (DTW), and Deep learning 1-dimensional Convolutional Neural Networks (1D CNN) models as a standalone model or into a multimodal machine learning framework by testing different fusion model strategies. BRU21 project is NTNU’s Research and Innovation Program in Digital and Automation Solutions for the Oil and Gas Industry. Read more about BRU21 program here https://www.ntnu.edu/bru21 Show less

Research Assistant/Geophysicist

• Jun 2017 - Jun 2018

Contribute to the development of e-learning GeoCLASS modules within the CASE consortium. The e-learning modules are based on various geological and geophysical topics. My main responsibilities include the design and theoretical basis for geophysical modules. • Seismic velocities and time-depth conversion • Understanding of the seismic reflection amplitudes (AVO/AVA)Coding development for zero-offset wave propagation through a periodical layered medium by using Chapman rock physics model of equant porosity medium with aligned mesoscale fractures. Effective interval Q estimations from drift gradients in the Norwegian North Sea and interpretation of the attenuation model in terms of geological information of the area, in-situ conditions, and attenuation mechanisms.

Teaching Assistant in Seismic Interpretation

• Jan 2017 - May 2017

Help students with their seismic interpretation exercise. In addition, give them some guidance and support for their final project. The seismic interpretation project expose students to work with real data following the standard workflow and gaining some skills handling Petrel. Firstly, working with 2D sections to have an idea of the regional geological framework and then integrating this with 3D data and well information (VSP, logs and cores). The main tasks of the project include seismic and well data QC, seismic facies analysis, petrophysical interpretation, seismic well-tie (synthetic seismogram generation), horizons and faults interpretation, seismic attribute extraction and analysis, depth conversion, prospect evaluation, risk assessment, calculate volumetric with further well proposals.

Long-Internship

• Mar 2010 - Oct 2010

The position within the company was a long internship in which I had to apply a new method for building a 3D velocity model from a 2D offshore survey in the Gulf of Venezuela. • This work helped me keep in touch with the real and general framework and workflow within exploration, offshore and gas field in the most important oil company in my native country. Also, I gained knowledge about seismic interpretation, seismic processing and building of velocity models. Furthermore I had to manage two useful and technological interpretation software such as LANDMARK and GOCAD. • 2D Seismic interpretation in an offshore area, about 5000Km2 (Golf of Venezuela).
