The SPE San Joaquin Valley Section's young professionals (YPs) have continued to contribute to the learning of their peers through a series of events that give YPs the opportunity to benefit from experts. Recently, they got together to learn more about continuing education and online education offered by top schools in the region. The YPs held a safety and leadership event at which participants talked with Gaurdie Banister, chief executive officer of Aera Energy. Banister shared his career journey in the oil and gas industry along with his personal experiences that have influenced his career. Representatives of the Viterbi School of Engineering at the University of Southern California (USC) answered questions from YPs in an information session in Bakersfield, California.
SPE Online Education recently added a new web-based resource for technical content–Industry Interviews. These are 30-minute audio interviews with experts about their personal and professional experiences in the oil and gas industry. Recorded live, the interviews are archived and available on demand for free for SPE members. Click here to visit the Interviews page.
Reservoir simulations constitute a cornerstone to predict the flow of fluids through porous media. Various numerical models called simulators are developed to simulate the performance of hydrocarbon reservoirs. These models are used in field development since production forecasts are necessary to make investment decisions. Nowadays, numerical simulators are widely used by reservoir engineers.
In recent times, machine learning applications have garnered the interest of the oil and gas industry due their unorthodox approach to creating complex models. The more historical data that can be provided in the training phase of the computation, the more accurate the predictions utilizing less time and computational power required by the alternative. The alternative, reservoir simulation applications, require more robust hardware for processing large amounts of data in sophisticated ways. This will require several iterations and may require long computation to validate the model. Running time for a simulation is dependent on software, which can be dependent on hardware. This creates a matrix of time and resources needed to complete simple to complicated simulations.
A few studies have proposed the use of the Lanczos decomposition method in reservoir simulation studies. The attractiveness of this method appears to be the avoidance of time stepping in simulation and allows the computation of reservoir pressures at any given time directly.
In this study, two new simulators were developed using Lanczos Decomposition Method (LDM) and Conventional Implicit Time-Stepping Method (ITSM). The study focuses on 2-D flow for slightly compressible fluid of constant viscosity with multiple wells. Derivation of the model equations was performed using the continuity equation for both methods through the use of MATLAB. The simulators were written using the MATLAB programming language. The simulators developed in this study are capable of assigning uniform and non-uniform gridblock distribution; porosity and permeability distributions, as well as developing various production and injection scenarios for single or multiple wells depending on different areas of application. Validity and accuracy of the 2D flow simulator were examined by comparing simulation results with that obtained from the commercial software called ECRIN. The results of the simulator were almost identical with the results obtained from the commercial software. During the model runs, the CPU time of the two simulators were compared. A special case was also studied for a single well with variable rate history using both ITSM and LDM written with FORTRAN.
To date, in petroleum engineering literature, there is no work published that compares the performances (in terms of computational aspects as well as CPU times) of the Lanczos method and the conventional implicit-time stepping method.
Most people who sign up for a MOOC – a massive open online course – never finish it, often completing less than half of the work. But does that mean they didn't get value from it? Should I Consider Graduate School? Graduate school can have a big impact on your career, but it isn't for everyone. Be clear about your expectations and what you hope to accomplish when pursuing an advanced degree.
Most people who sign up for a MOOC – a massive open online course – never finish it, often completing less than half of the work. But does that mean they didn't get value from it? Otto Alcantara Santos, Petrobras, discussed the extensive training program for development of the company's engineers and the positive results it has produced. Each of us is accountable for our own professional development. SPE is expanding its training course program to help you expand your capabilities.
The report was written by a steering committee of SMEs with industry input from an SPE summit as well as members from SPE online communities. It is based on discussions and conclusions from the summit and is intended to provide guidance on an industry-wide safety management data sharing program. IoT has become a popular phrase in various industries. For upstream oil and gas operators, an IoT infrastructure may present an opportunity improve quality control on their projects, potentially reducing costs and increasing production. The SPE Board of Directors has realigned the Production & Operations and Projects, Facilities & Construction technical disciplines under one Technical Director. How do mooring systems reduce risks of hurricane damage to mobile offshore drilling units?
As laptops become smaller and more ubiquitous, the old-fashioned way of taking notes by hand still has advantages. For technical innovation and skill progression for individuals and institutions, continual learning and exposure to new ideas is vital. Summarizing the results of a leadership survey by Bain and Company, this HBR article describes the traits of an inspiring leader. The oil and gas industry has a remarkable story to tell. SPE’s energy education public outreach program Enery4me highlights how energy works in our everyday lives to school students and teachers and promotes the career opportunities in the upstream petroleum sector.
Change is constant in the oil and gas industry, bringing an increase in operational risk. As companies acquire and develop assets around the world, they must reduce their risk exposure by improving operational integrity. A recent webinar provides six reasons for ensuring strong HSSE policies are included in a company's ERP system. SPE Distinguished Lecturer Patrick Hudson discussed the types of safety culture found in organizations and the ways in which companies can improve their handling of noncompliant behaviors by employees. Gone are the days when missing a few fingers is a badge of honor in the oilpatch.
In this case, a film guides the audience to make positive, personal choices whenever planning and operating a work at height. Safety depends on developing a dedicated culture mind-set and mitigation of risks, from the planning and engineering phases to the work site. These papers selected by OGF technical paper editor Gerald Verbeek present various practices for reducing and eliminating the number of incidents. The new satellite will build on the success of the company's demonstration satellite Claire, which has performed over 2,500 observations of oil and gas facilities as well as other natural and industrial sources of carbon dioxide and methane. Pipeline approvals can be a polarizing topic and advocacy for their viability is crucial for companies.
SPE webinars are free to members and include live presentations, on-demand online training courses, and videos sponsored by the SPE Foundation. Expert Hour Webinars are corporate-sponsored presentations that provide technical content to both SPE and non-members. Take a look at SPE Connect! This is where SPE members can virtually communicate, exchange knowledge, and collaborate with other members from around the world. SPE members get registration discounts to hundreds of conferences, workshops, and courses every year.
