Petroleum exploration is where a rig or ship is used to drill into the earth or seabed to locate oil reserves.
For offshore exploration a drill ship, jack-up drilling rig or floating drilling rig can be used. For onshore applications mobile drilling rig is used.
Onshore and offshore breezes are local winds that result from temperature differences between land and water. During the day, the land heats up faster than the ocean, causing the air above the land to rise and creating a low-pressure area; this draws cooler air from the ocean towards the land, resulting in an onshore breeze. Conversely, at night, the land cools more quickly than the water, leading to higher pressure over the land and causing the cooler air over the ocean to flow towards the land, creating an offshore breeze. These breezes are driven by the uneven heating of land and water and can influence local weather patterns.
One good thing about petroleum is that it allows our vehicles to run. Another good thing about petroleum is that it allows many people to have opportunities for employment in petroleum exploration.
An oil rig is a structure used for drilling and extracting oil and gas from beneath the Earth's surface, typically located offshore or on land. Petroleum engineering, on the other hand, is a field of engineering focused on the exploration, extraction, and production of oil and gas resources. While oil rigs are the physical sites where extraction occurs, petroleum engineers are responsible for designing and optimizing the processes and technologies used in oil and gas production.
Approximately 30% of the world's oil production comes from offshore sources. Offshore oil drilling involves extracting petroleum from beneath the seabed, and it plays a significant role in meeting global energy demands. The percentage can vary based on market conditions, technology, and geopolitical factors influencing oil production.
People build offshore wind farms primarily to harness the strong and consistent winds found over the ocean, which can produce more energy compared to onshore wind farms. Offshore locations also minimize land use conflicts and can be positioned closer to urban centers where energy demand is high. Additionally, these projects contribute to reducing greenhouse gas emissions and transitioning to renewable energy sources, helping to combat climate change. Moreover, offshore wind farms can stimulate economic growth through job creation in construction, maintenance, and technology sectors.

onshore means it is on land and offshore on sea.
Petroleum is produced from wells offshore and onshore. I assume you are asking which countries produce oil, and I have included a link with the major oil producing countries. Saudi Arabia is the top producer.
Assab is an onshore oil field
onshore is oil well drilled on land. offshore is oil well drilled in sea/ocean.
Onshore/offshore dichotomy is way of allocating the revenue accrued from exploitation and exploration of crude oil. Such revenue is divided into onshore revenue (revenue accrued from oil drilled onshore (on land) and offshore revenue (accrued from oil drilled from littoral zone).The dichotomy implies the revenue from offshore crude belong to a sovereign nation and not to the coastal communities, and thus must be shared among the states that make up the nation, while onshore revenue belongs to the coastal communities (termed oil producing communities) on which land the crude is drilled.
I assume you mean "difference" and not "deference". Onshore means on dry land. Offshore means out in the water. Offshore drilling is out in the water, like in the Gulf of Mexico. Onshore drilling means on land, like in Wyoming and Texas.
Offshore winds will blow the unwary captain onto shoals or reefs. Onshore winds will blow the unwary captain away from his next landmark or landfall.
An offshore platform is a structure that is installed over as group of wells that was drilled by an offshore drilling rig. The function of the platform is to produce the oil from these wells. A platform can be mounted to the seabed or could be a floating type platform. Offshore drilling rigs are for drilling the wells and are mobile and moved from area to area. Onshore drilling rigs are mobile units too and are moved from pad to pad for drilling and exploration. After a well is drilled onshore, a wellhead is installed on the well. There is no need for a platform as this only economically viable in offshore applications. There have been cases where an offshore well was drilled from land into the sea, but operated from land. This can only be possible if the oil formation is not too far offshore.

on-shore
natural gas exploration and drilling, which accounts for 80 percent of all U.S. drilling activity, will be focused inland, petroleum exploration is shifting toward more offshore locations.
