Navy presentation to the Moffett Field Restoration Advisory Board, September 11, 2008: Hangar One Engineering Evaluation/Cost Analysis Detailed Cost Estimate
This document summarizes a post well analysis project by TGS to analyze 80 exploration wells drilled in the Norwegian Sea. The analysis will evaluate factors related to the presence of reservoirs, traps, seals, and hydrocarbon charge. Data will be compiled in a GIS-based database and visualization tools to allow querying and analysis of patterns in well successes and failures. The goal is to improve understanding of the petroleum systems and reduce future drilling risks.
The document discusses the Strategic Surface Route Plan (SSRP) which aims to balance supply and transportation costs to lower overall supply chain costs while maintaining velocity. The SSRP directs consolidation of shipments at consolidation and container points and deconsolidation at transportation control and staging points. A five version plan is outlined to develop the SSRP and integrate it with a Strategic Air Route Plan to optimize routing for over 60% of air and surface shipments globally.

Presentation by Karina Stockmann and Ludwig Schenk, BSH (DE), at the Delft-FEWS - International User Days, during Delft Software Days - Edition 2017. Thursday, 26 October 2017, Delft.
In this paper, we provide a proof of concept on how to model and forecast average Vessel Service Time (VST) using Long Short-Term Memory (LSTM) Recurrent Neural Networks (RNNs). The proposed model is learned from the Automatic Identification System (AIS) data by using machine learning. Geohash area (GeoArea) with a certain precision, convex hull area (ConvArea), and average vessel proximity (Delta) are mined for the port of Singapore every hour. These three metrics are used to calculate port spatial complexity (SpComplexity) and port spatial density (SpDensity) indicators. In addition, we propose an algorithm to mine the VST and associate that with the mined GeoArea, ConvArea, and the calculated indicators (i.e., SpDensity and SpComplexity). Then, an LSTM model is trained and subsequently tested to forecast future V ST, as Port Authorities are increasingly relying on data-driven insights for decision-making purposes. We trained and tested several LSTM models with four different time aggregation granularities (2; 4; 6; and 8 hours) and provided performance comparisons between them in terms of Mean Square Error (MSE). The experiments emphasized the feasibility of the proposed LSTM model to forecast VST.

Black Oil Reservoir Simulation Model Mis-Match Assessment through Computer-As...Carlos R. Conde
This document is a thesis submitted by Carlos Rafael Conde Rondon to the Robert Gordon University in partial fulfillment of the requirements for a Master of Science degree in Petroleum Production Engineering. The thesis assesses mis-matches between a black oil reservoir simulation model and actual field production history for the Costanero Field in Venezuela through computer-assisted history matching. Specifically, it aims to reduce deviations between the model and historical production data for one of four reservoir variables. The results showed that the model reasonably matched the reservoir behavior and that water cut deviations were lowest. A correlation analysis revealed strongly correlated input parameters within two regions, and a Hessian analysis removed parameters for one region. The new approach required 47% less computational effort than conventional history

ResAssure - The World’s Fastest Reservoir Simulator | A Revolution in Reserve...Stochastic Simulation
This Presentation Will:
1. Introduce a new way of evaluating reservoir uncertainty with RESASSURE
2. Illustrate the concepts used
3. Highlight the benefits achieved
4. Demonstrate the value of the results
Stochastic Simulation has unleashed the world’s fastest reservoir simulator, ResAssure, which is set to revolutionize production planning and reserves reporting in the Oil & Gas industry.
ResAssure easily computes > 1 Million realisations within a 24 hour period, a fraction of the time it currently takes with traditional methods and software packages. The release of ResAssure marks a significant milestone in the history of reservoir simulation – the first real industry technology advance in 30 years.
Dr Wadsley, Chief Technology Officer at Stochastic Simulation, commented “ResAssure is capable of quickly generating more accurate reserve estimates than is currently possible by any other software system. The approach taken generates a complete distribution of history matched models all of which are consistent with the geological model and observed production history. The time taken for this is orders of magnitude faster than current history matching methods.”
“Field development planning based on ResAssure’s distribution of models (rather than just upon a single history-matched model using conventional methodologies) will significantly reduce uncertainty and risk.” he added.
By enabling faster and more accurate analysis of dynamic subsurface geological data than has previously been possible, ResAssure markedly reduces the risk in the development of oil and gas fields by narrowing the range of uncertainty in reserves estimates: thereby supporting better production and financing decisions, with substantial increases in project ROI.
ResAssure’s innovation in reservoir simulation solves fully-implicit, dynamic three-phase fluid flow equations for every geological realisation. The speed breakthrough was achieved by a combination of proprietary algorithms, polygonal gridding and aggressive spatial coarsening and time stepping, based upon a conventional finite-difference discretization of the reservoir.
Key Insights Identified:
1. Consistency between volumetric, material balance and fractional flow places very strong constraints on feasible reservoir models.
2. The mathematics of reservoir simulation is NOT complex – it is the geology which is complex.
3. Reserves uncertainty is not quantified, but estimated from current ‘best’ estimate in an ad hoc unsystematic way.
4. What’s the point of preserving mass balance in the simulator when the hydrocarbons in the reservoir are imprecise and we don’t include all production data – mass balance should act to regularise our solution, not to define it.
5. The role of reservoir simulation is not to compute an exact solution of a poorly defined geological model – it is to define a range of feasible reservoir models and associated production forecasts.
Two Dimensional Flood Inundation Modelling In Urban Area Using WMS, HEC-RAS a...Amro Elfeki
This research presents a two-dimensional flood inundation modelling in urbanized areas when some features such as roads, buildings, and fences have great effect on flood propagation. Wadi Qows located in Jeddah City, Saudi Arabia was chosen as case study area because of the flood occurrence of 2009 causing lots of losses either economic or loss of life. The WMS and HEC-RAS program were used for a hydraulic simulation based on channel geometry built by incorporating urban features into DEM using GIS effectively. A resampling method of DEM 90 × 90 m become 10 × 10 m grid cell sizes was conducted to produce a higher resolution DEM suitable for urban flood inundation modelling. The results show that a higher resolution leads to increasing the average flood depth and decreasing the flood extent. Although the change of the grid cell sizes does not affect its elevation values, this approach is helpful to perform flood simulations in urban areas when high resolution DEM availability is limited. In addition, the integration of WMS, HEC-RAS and GIS are powerful tools for flood modelling in rural, mountainous and urban areas.

UK ATC 2015: Dynamic Explicit Analysis & Assessment of a Ships Steering GearAltair
The document describes a dynamic analysis of a ship's steering gear that was conducted to assess its response to underwater explosions. The analysis involved building a finite element model of the steering gear components, applying pressure pulses and velocity impulses to represent explosions, and analyzing the results to evaluate plastic strain, component stresses, actuator forces, and other metrics. The analysis found some localized plasticity but confirmed the design meets requirements for withstanding shocks from explosions longitudinally, athwartships, and vertically. Minor design improvements were also identified.
The document outlines services provided across enhanced oil recovery, acquisitions and divestitures, field studies, and SEC/bank reserves. Key services include waterflood analysis, EOR process selection and evaluation, package preparation for divestitures, prospect ranking for acquisitions, type curve studies based on geology and completion metrics, detailed analysis of PDP, PDNP, PUD potentials, and quality assessment/control and project management for SEC/bank reserves reporting.

2) It analyzes a case study comparing the three development concepts for an offshore gas field using both methodologies.
3) The stochastic multi-attribute decision model found that a semi-submersible platform with 6 production wells maximized expected NPV by accounting for uncertainty in cost factors, while the NPV valuation approach favored a different number of wells.
Probabilisitc analysis of marine fuels in emission controlled areasKamal Kannan
This document summarizes a probabilistic analysis of marine fuel options in emission controlled areas. It outlines the methodology used, which involved deterministic and probabilistic decision analyses of three fuel alternatives: a two-stroke diesel engine with scrubbers, an LNG-fueled engine, and a dual-fuel engine. The analysis found the optimal decision was diesel under deterministic analysis but changed to LNG when accounting for uncertainties in fuel prices, regulations, and other factors. Sensitivity analysis showed LNG became optimal with small changes to diesel and LNG prices or engine downtime. Risk analysis found the optimal decision shifted from diesel to LNG to dual-fuel as risk aversion increased.

Complying with EPA's Guidance for SO2 DesignationsSergio A. Guerra
EPA is under a Court order to complete the remaining SO2 designations for the rest of the country in three additional rounds. On March 20, 2015 the EPA released an updated guidance for 1-hr SO2 area designations. The two options included are compliance through dispersion modeling or ambient monitoring. Of these two options, dispersion modeling is the fastest and most cost effective one to characterize SO2 air quality. However, this compliance demonstration can be challenging given that AERMOD tends to produce overly conservative concentration estimates. Source characterization techniques and probabilistic techniques may be used to achieve compliance with the 1-hour NAAQS. Three advanced methods discussed: 1) Equivalent Building Dimensions (EBD); 2) Emission Variability Processor (EMVAP); 3) 50th Percentile Background Concentrations.

Use of Wind Tunnel Refinements in the Dispersion Modeling Analysis of the Ala...Sergio A. Guerra
The proposed Alaska LNG Gas Treatment Plant project required dispersion modeling to evaluate impacts on ambient air quality standards. Initial modeling found inconsistent results due to complex building arrangements of two nearby facilities. Wind tunnel testing was used to determine equivalent building dimensions to refine building inputs, which significantly reduced predicted concentrations. The environmental regulator approved the wind tunnel analysis approach. The modeling now demonstrates operations will not cause exceedances of air quality standards.

The document provides an update on vapor intrusion sampling activities at the Former Naval Air Station Moffett Field. It discusses the results of indoor air sampling conducted in 2017 at 23 buildings on site. 211 total samples were collected, including indoor, outdoor, and subsurface samples. Analysis showed indoor air concentrations exceeding cleanup levels in 3 buildings, designating them as Tier 1. Most other buildings were designated Tier 3A, as indoor levels were below cleanup levels but above outdoor background. A future report will provide detailed tier evaluations and recommendations for additional response actions if needed.
The Moffett RAB has been meeting since 1994 to advise the Navy on the environmental cleanup of Moffett Field. Meetings were initially monthly but have decreased in frequency over time to twice yearly. The mission of the RAB as stated in the 1995 charter is to advise the Navy on the cleanup and allow community discussion. At their April 2017 meeting, RAB community members recommended staying separate from another advisory board, investigating alternating meetings with EPA and Navy, and expanding community outreach and involvement from local universities. Near term activities include starting to amend the RAB charter and continuing outreach.
Endophyte Assisted Phytoremediation of TCE and Derivatives Using Hybrid Popla...Steve Williams
This document summarizes a study on using hybrid poplar trees and their associated endophytic microbes to remediate trichloroethylene (TCE) and derivatives from contaminated groundwater. Researchers screened poplar endophytes and identified one that could degrade TCE into chloride ions. Field tests showed poplar trees inoculated with this endophyte had higher chloride levels in soil, indicating TCE degradation, compared to uninoculated trees. Monitoring wells near inoculated tree plots also showed decreasing TCE and PCE levels over time, demonstrating the endophyte-assisted phytoremediation approach.
