Interview Questions.

Question 1. What Are Offshore Installations?

Answer :

Oil and fuel offshore installations are industrial towns at sea, wearing the employees and gadget had to get entry to reservoirs thousands of feet below the seabed, and maintain continuous hydrocarbon manufacturing. The most vital features are drilling, preparing water or gas for injection into the reservoir, processing the oil and gasoline earlier than sending it ashore, and cleaning the produced water for disposal into the sea. 

Big constant systems may have these types of features in a single place, but smaller structures may be dedicated to just one characteristic, such as drilling or gas compression. Some installations may be moved from one location to some other, as an instance cellular drilling rigs and manufacturing FPSOs.

Question 2. What Are Onshore Installations?

Answer :

These are installations on land and commonly close to the sea which get hold of oil and fuel from offshore installations via pipeline (or inside the case of oil from time to time by means of tanker). These installations prepare the liquid merchandise for further refining - but they're not the refineries. They also take the herbal fuel and make it suitable for piping into the National Grid. At some installations fuel drinks are processed.

Question three. What Actually Happens Offshore?

Answer :

The famous image of offshore work frequently facilities on a muddy drill floor, wherein wells are drilled to goal the reservoirs of oil and gasoline below the surface - but that is only the start of the tale. 
The pinnacle cease of each production nicely sprouts a branching collection of pipes, gauges and valves known as the 'Christmas tree'. At this point, crude oil is a warm, frothy, corrosive, excessive-stress fluid containing fuel, water and sand. 
After separation, the crude oil is metered and pumped into the pipeline, or stored until sent ashore by tanker. 
The gas separated from the oil can be used for fuel, or compressed and piped to shore or re-injected into the reservoir. Any fuel that can not be used is burnt inside the platform's flare, little or no gasoline is now flared. 
Processing structures for the gas fields of the southern North Sea are fantastically simple. The gasoline liquids are eliminated and then the gas is compressed, cooled, dehydrated and metered before being piped to shore. 
All production and drilling structures must be monitored constantly for leaks, in view that oil and fuel are dangerous and extraordinarily flammable. 
There is not any mains electricity offshore! Power must be generated at the set up to drive production and drilling device, and to support lifestyles. 
In other words, offshore installations are full of complicated equipment and systems that want to be operated and maintained properly by way of especially skilled folks who recognize the era and the techniques worried, and who can work collectively in integrated groups.

Question five. How Sap Solution Integrates Upstream Oil & Gas Operations?

Answer :

Upstream oil & gasoline manufacturing involves particular requirements and commercial enterprise approaches which might be particular to this enterprise. Unlike inside the downstream sector, enterprise techniques inside the upstream oil & fuel sector are not properly included. This is in part due to organizational issues and partly because of the reality that upstream agencies typically use a handful of first-rate-in-breed packages and severa Excel spreadsheets, rather than a properly-included answer. 

These enterprise processes encompass paintings-over management, production planning and allocations, contractor control and protection scheduling, production reporting, and others. Without clean visibility into field variables and constraints, operations planners do not have the records they need to make the high-quality choices. This regularly consequences in sub-most excellent planning, inefficient use of each bodily and human resources, higher prices, and elevated danger.
