Mooring analysis involves designing an offshore mooring system to withstand extreme environmental conditions like 100-year storms. Key factors in the mooring layout include the strength of each mooring line, seabed topography, and directions of wind, waves and currents. Common mooring patterns are distributed to balance loads and provide redundancy. Analysis calculates line tensions and vessel excursions in storms, traditionally analyzing mooring and risers separately but now integrated. The purpose is to ensure the vessel stays within acceptable distance limits under worst loads.
Hydril provides reliable deepwater drilling systems for offshore oil and gas exploration. Their standard systems are designed to operate for an entire year without downtime and can reach depths of 12,500 feet below sea level. Hydril's modular design allows for reduced installation and maintenance times. Their deepwater multiplex blowout preventer control systems set benchmarks for reliability in critical deepwater environments.
The document discusses completion strings and accessories used in well completions, focusing on tubing and packers. It describes the purpose and selection considerations for production/injection tubing, including material grade, dimensions, and operational parameters. It then explains the main functions of downhole packers, including annular isolation, anchoring, casing protection, and zone separation. It provides an overview of the main packer families and generic setting mechanism, which involves using a cone to force slips outward against the casing wall and compressing a sealing element.
The document discusses the fabrication of offshore platforms in Thailand. It describes the typical configuration of jackets and topsides, including details like 4 legs, 6-20 drill slots, and integrated 4-column topside structures. It outlines welding processes like SMAW and SAW used during fabrication. Quality control measures are summarized, including welding procedure specifications, qualification tests, and non-destructive testing. Material control and corrosion protection methods are also briefly outlined. Fabrication yard layout plans and sequences are shown for both jacket and topside fabrication.
1) Sand production from unconsolidated reservoirs can be triggered during initial flow or later due to pressure changes and can vary in severity, sometimes requiring remedial action and sometimes being tolerated.
2) The article reviews methods for predicting, controlling, and preventing sand production, focusing on gravel packing as the most popular method for completing sand-prone wells.
3) Factors like inherent rock strength, stress levels, fluid turbulence, and pressure changes can cause sand production by detaching and transporting sand grains. The challenge is to control sand without reducing well productivity.

This document discusses subsea separation as a new frontier for chemical engineers. It outlines the increasing demand for oil and gas production from deepwater fields and the challenges of subsea production systems. Subsea separation techniques including horizontal separators, vertical separators, caisson systems, and compact cyclonic separators are presented. The document highlights the need for further research to improve the understanding and design of compact subsea separators. Academic work at Cranfield University involving testing a prototype gas-liquid pipe cyclonic separator is summarized. The findings provide useful information on multiphase flow regimes inside separators and how they can influence phase separation performance.
Chris brooks storage tanks inspection, maintenance and failureSreekumar K S
API 653 tank inspections are important to identify problems and prevent tank failures. Inspections should be conducted by certified inspectors following proper protocols, including visual and ultrasound thickness testing and vacuum testing of floor seams. Tank maintenance includes regular visual inspections, keeping records, and conducting API-653 inspections every five years. Common causes of catastrophic tank failures include improper welding procedures resulting in a lack of weld fusion, not using certified welders, weld deterioration over time, overfilling tanks, and using contractors not qualified to API standards.
Performance prediction in gas condensate reservoirGowtham Dada
This document discusses performance prediction in gas condensate reservoirs. It describes key characteristics of gas condensate reservoirs including the production of both gas and condensate liquids. Condensate formation occurs near the wellbore as pressure drops, which can impair well productivity over time due to liquid dropout. The document outlines factors that influence multiphase flow behavior in the reservoir such as interfacial tension, gravity effects, relative permeability, and non-Darcy flow near the wellbore. It also reviews methods that can be used to reduce condensate banking issues like hydraulic fracturing, solvent injection, and wettability alteration.

C1. Introduction to Offshore Production TechDavid Seow
The document discusses offshore oil and gas production and focuses on floating production storage and offloading (FPSO) platforms. It describes FPSOs as having four key functions - floating, production, storage, and offloading. FPSOs are preferred for remote locations, smaller marginal fields, deep waters where fixed platforms are not viable, and areas where mobility is needed to avoid harsh weather. Their modular, self-contained design also makes them easier to decommission and reuse compared to fixed platforms.

It provides examples of the Greater Plutonio and Falcon FPSOs and outlines the typical decommissioning process for offshore platforms. FPSO selection and design is influenced by criteria like water depth, weather limits, and processing needs of the field being developed.
Reservoir development plans require dynamic strategies to optimize production. Recovery methods can be initiated at any stage to improve efficiency. It is common for development plans to change over time due to new understanding, performance, constraints, economics or technologies. Screening studies for improved or enhanced oil recovery methods should consider technical feasibility as well as availability of resources and include decision analysis to define robust project options early. Preliminary performance predictions using simple models can help evaluate recovery process potential in a reservoir.
