Recent moves by the Moscow-based OAO Gazprom, the world's largest oil and gas company, have riled Western energy companies already working in Russia. Two situations in particular have brought issues to a head: one involves development of gas reserves…
As the search for oil and gas progressed, platforms were located further offshore in deeper waters. This necessitated the requirement for offshore living quarters located on the platforms. Thus, the generation of electricity became a natural part of…
At present, offshore drilling operations often use buttress thread casing as surface casing. The design conception of buttress thread casing is comes from the offshore drilling's demands and this kind of casing is mainly used as surface casing. This…
In the offshore engineering community, reliable deep-water anchor performance is critical for mooring floating platforms such as Mobile Offshore Drilling Units. In a typical installation, an anchor is fully embedded into the seabed (up to 100 m).…
This paper presents some key operational challenges in the petroleum industries in which advanced control and model-based optimization has or may have a significant impact. This includes stabilizing control on an individual well level, model-based…
To monitor third-party damage (TPD) activities on oil transmission pipeline such as man-made drilling, hammering and excavating on metallic pipe, acoustic method is proposed based on wavelet packet energy feature extraction and least square support…
To avoid drilling hole and stealing oil in pipeline, a method of monitoring man made damage in advance is offered based on low frequency vibration signal. The signals come from the complex activities such as welding, hammering and damaging metallic…
In 1985 an API (American Petroleum Institute) task committee, from a cross section of the oil-producing business, was formed to update API recommended practice (RP) 500B-Classification of Locations for Electrical Installations at Drilling Rigs and…
In recent years, offshore oil and gas fields are being developed worldwide in increasingly deeper water. Offshore drilling and production projects are currently underway in water depths approaching 3,000 meters in several areas of the world. Seabed…
