This document provides an overview of petroleum exploration. It describes the life cycle of an oil and gas field, including the exploration, appraisal and development, production, and abandonment phases. The exploration process involves studying surface features like oil seeps and outcrops to identify potential hydrocarbon reservoirs. Subsurface data from techniques like seismic surveys is also used. Basin analysis examines sedimentary basins where source rocks may have generated hydrocarbons that migrated and were trapped in reservoir rocks. The goal is to identify "petroleum plays" with the highest probability of containing producible oil and gas to justify drilling exploratory wells. Subsurface data acquisition methods help map underground geology before drilling begins.Petroleum Formation Evaluation Overview

Petroleum reservoir performance overviewAndi Anriansyah
油
This document provides an overview of petroleum reservoir performance terms and concepts. It begins with definitions of key reservoir fluid terms like fluid, density, solution gas, critical saturation, bubble point pressure, gas cap, associated and non-associated gas, viscosity, condensate, and formation volume factor. It then describes hydrocarbon classifications and recovery methods. The document outlines natural driving forces in reservoirs including solution gas, water drive, and gravity drainage. It also discusses enhanced oil recovery methods such as water flooding, thermal recovery, and microbial flooding. Suggestions are made to improve future editions covering the petroleum industry overview.Petroleum well completion overview
Petroleum well completion overviewAndi Anriansyah
油
This document provides an overview of well completion processes and equipment. It describes common casing types like surface casing, intermediate casing, and production casing. It explains the functions of casing to protect the wellbore, isolate fluid zones, and provide a conduit for tools. The document outlines the typical steps in a well completion, including running and cementing casing, perforating, stimulating, gravel packing if needed, and installing tubing and a Christmas tree. It provides details on related equipment like centralizers, float shoes, and packers. The document is intended as an introduction to well completion concepts and components for educational purposes.Introduction - Artificial lift
Introduction - Artificial liftAndi Anriansyah
油
This document discusses artificial lift methods used in oil production. It covers three commonly used artificial lift equipment: sucker-rod pumps, gas lift, and electric submersible pumps (ESPs). As the reservoir pressure declines after initial production, artificial lift methods are needed to supplement and replace the natural reservoir pressure in lifting oil to the surface. Sucker-rod pumps are driven from the surface to pump oil up the wellbore via the sucker rods. Gas lift uses injected gas to reduce the density of downhole fluid, making it easier to lift. ESPs are submersible pumps placed downhole that use an electric motor to pump fluid up.Petroleum economics
Petroleum economicsAndi Anriansyah
油
Investment decisions are among the most important decisions an organization can make as they are capital intensive, irreversible, and high risk. This document discusses the main elements of economic investment analysis including calculating a project's cash flow over its lifetime while accounting for inflation, time value of money, and uncertainty. It describes key decision criteria like net present value and internal rate of return to evaluate whether a project should be accepted or rejected based on whether its NPV is positive or its IRR exceeds the discount rate. The quality of the economic analysis depends on accurate cash flow projections and using the proper discount rate.An introduction to oil and gas production
An introduction to oil and gas productionAndi Anriansyah
油
This document provides an overview of the oil and gas production and shipping industry, including exploration, upstream production facilities, midstream facilities, and transportation. It describes the key stages and facilities involved, from exploration and drilling to separation, processing, storage, pipelines and export. The upstream section involves wellheads, manifolds, separation and processing facilities. Midstream includes gas plants for processing, pipelines for transportation, and LNG facilities for liquefaction and regasification. Various offshore and onshore production structures are also outlined.WELL COMPLETION, WELL INTERVENTION/ STIMULATION, AND WORKOVER
WELL COMPLETION, WELL INTERVENTION/ STIMULATION, AND WORKOVERAndi Anriansyah
油
This document discusses various well completion, intervention, and workover topics including:
- Well completion involves preparing the well for production by installing equipment like casing and tubing.
- Open hole and cased hole completions are described, along with advantages and disadvantages of each.
- Well intervention operations like scale removal, acidizing, and sand cleaning are performed during production.
- Formation damage from fluids introduced into the well is also discussed.
- Stimulation techniques like acidizing and hydraulic fracturing aim to increase well productivity. The document outlines the processes, equipment, and evaluation of these operations.
- Other topics covered include intelligent well completions, perforating, sand control, squeeze cementDrilling operations
Drilling operationsAndi Anriansyah
油
The document discusses drilling operations including directional drilling, casing design, and bottom hole assembly components. Directional drilling involves deviating wellbores from vertical to intersect targets. Key directional drilling types include "J", "S", and slant wells. Casing is designed and set at depths to isolate formations and support wellheads. Bottom hole assemblies use drill pipe, heavy drill pipe, drill collars, and bits to transfer rotation and weight to drill the well.Ad

How to Un-Obsolete Your Legacy Keypad DesignEpec Engineered Technologies
油
For any number of circumstances, obsolescence risk is ever present in the electronics industry. This is especially true for human-to-machine interface hardware, such as keypads, touchscreens, front panels, bezels, etc. This industry is known for its high mix and low-volume builds, critical design requirements, and high costs to requalify hardware. Because of these reasons, many programs will face end-of-life challenges both at the component level as well as at the supplier level.
Redesigns and qualifications can take months or even years, so proactively managing this risk is the best way to deter this. If an LED is obsolete or a switch vendor has gone out of business, there are options to proceed.
In this webinar, we cover options to redesign and reverse engineer legacy keypad and touchscreen designs.
