The seismic sensors will be dropped by six autonomous aerial drones and later be retrieved by an unmanned ground vehicle instead of conventional manual deployment and recovery by ground-based teams. AUVs aren’t limited to inspections and pipeline surveys. Deployment of a flotilla of AUVs to work on a project, and the communication among them, may someday lead to a subsea Internet of Things. The Hail 3D transition-zone seismic survey carried out by ADNOC is located in a UNESCO world-biosphere reserve. Effective environmental and ecological management throughout the project was attained through working procedures and monitoring programs.
The growing popularity of model-based optimization work flows has resulted in an increase in their application to field cases. This paper presents an unbiased stochastic data-driven work flow in which surface and subsurface uncertainties are accounted for and their effects on facilities design and operational decisions are quantified. Three-dimensional reservoir models are best created with a combination of well logs and 3D-seismic data. However, the effective integration of these results is not easy because of limited seismic resolution.
The complete paper describes the potential global scientific value of video and other data collected by ROVs. The feasibility test conducted offshore Abu Dhabi demonstrated the successful and safe deployment, seismic-data acquisition, and retrieval capabilities of the AMV and 3D sensor array. Operators for remotely operated vehicles will be getting more remote in the future as land-based control begins to become a reality.
There are growing opinions suggesting that the global Covid-19 pandemic will hasten the demise of fossil fuels. However, the prospect towards a predominantly renewable energy based world does not seem to be soon accomplished. Energy outlooks for the upcoming 20 to 30 years project a strong growth in renewables to becoming the largest source of power during that timeframe. Though, there is near consensus that demand for natural gas will robustly grow supported by its prevalent availability, the continuing expansion of LNG, and the relative cleanness of natural gas compared to other fossil fuels as well as being the raw material for clean hydrogen. In this session, panelists will shine a light on the energy transition from conventional fuels to renewables and the expected contribution of natural gas through that journey.
Thank you for attending the SPE Forum. Predicting the properties of reservoirs beyond the wellbore has been the cornerstone of reservoir characterization. The outcome provides the framework for efficient management and optimization of hydrocarbon reservoirs. Proper reservoir characterization affects all reservoir types and all stages during the life of a field. Far-field characterization encompasses seismic, electromagnetic, and other geophysical surveys.
A recent test proved the feasibility of using LiDAR on remote-controlled drones to create 3D maps of the inside of tanks, increasing the safety and efficiency of inspections. The seismic sensors will be dropped by six autonomous aerial drones and later be retrieved by an unmanned ground vehicle instead of conventional manual deployment and recovery by ground-based teams. The $43-million deal with Saipem will utilize a wireless underwater intervention drone and an ROV for intervention work on the Njord field in the Norwegian North Sea. Equinor said the contract is the first ever from an operator for advanced wireless drone services. Subsea inspection/repair/maintenance services have traditionally relied on vessel-based, ROV, or diver operations.
This paper presents a data set involving the pumping of multiple, unique chemical tracers into a single Wolfcamp B fracture stage. This paper introduces a new core-analysis work flow for determining resistivity index (RI), formation factor (FF), and other petrophysical properties directly from an as-received (AR) set of core samples. Houston-based Surge Energy drilled the Medusa Unit C 28-09 3AH well in the Midland Basin to a TMD of 24,592 ft, with a total horizontal displacement of 17,935 ft, or 3.4 miles. This paper discusses a project with the objective of leveraging prestack and poststack seismic data in order to reconstruct 3D images of thin, discontinuous, oil-filled packstone pay facies of the Upper and Lower Wolfcamp formation. A new technique that analyzes scanning electron microscope (SEM) images of formation samples has been used to measure porosity and total organic carbon (TOC) in the Wolfcamp Shale of the Delaware Basin in west Texas.
ExxonMobil’s rig automation experiment is accelerating, with plans to push the number of rigs in the system from three to nine. Drilling efficiency was improved by use of an automated pipe-handling system, which reduced the median time required for connection at one location by 20%. What is the Future Demand for Petroleum Engineers? Artificial intelligence can do some things faster and better than humans can. But that may allow engineers to focus on higher-value tasks.
For the upstream industry, where improvement in efficiency or production can drive significant financial results, there is no question that the size of the digital prize is huge. In this study, the authors use a quantitative seismic interpretation work flow (QSI) based on a rock-physics template in estimating the uncertainty of the geochemical properties of organic mudrocks of the Shublik formation of the Alaskan North Slope. This paper demonstrates how maintaining investment in high-quality 3D seismic during the last downturn, together with selective exploration, quality geoscience, application of new technologies, and efficiently maturing discoveries to early cash flow, was successful in sustaining future production. In this paper, the authors propose a least-squares Q migration (LSQM) method that combines the benefits of both LSM and Q prestack depth migration (QPSDM) to improve the amplitude fidelity and image resolution of seismic data. Happily, in this past year, we witnessed several examples of marriage between two themes—exciting technology advances and the recent economic downturn.
In tectonically influenced regions, potential hydrocarbon traps are subject to complex states of stress. This paper presents a coupled 3D fluid-flow and geomechanics simulator developed to model induced seismicity resulting from wastewater injection. Knowing which horizon crude oil flows from and in what proportions has been a major challenge for shale producers. Increasingly, they are turning to new technology to find the answer. Seismic imaging provides vital tools for the exploration of potential hydrocarbon reserves and subsequent production-planning activities.
