Deep-water well completion is a game of high risks. In such conditions, working in thousands of meters of water entails enormous pressures, frigid temperatures, and erratic geological formations. In deep waters, any mistake results not only in loss of time but also in complete machinery breakdowns at the cost of millions of Non-Productive Time (NPT)….
It is common for deepwater drilling to be lumped under unconventional oil production due to the high cost and risk associated with it, as well as the advanced technology required. But this is purely an operational matter rather than a geological one. In general, deepwater drilling is classified under conventional offshore production in petroleum engineering. This…
Oil transportation is one of those really critical pieces in the worldwide energy supply chain; it basically makes sure that crude oil and refined petroleum products can get around smoothly from where they’re made to refineries, storage sites, and then eventually the end-users. And depending on where the oil comes from, like if it’s coming…
In the oil and gas sector, keeping a well both productive and safe is pretty critical. A couple of terms you’ll often hear are well workovers and well interventions. They sound similar at first glance, but really they do not quite mean the same thing. Each one shows up with different aims, distinct kinds of…
Oil and gas exploration upstream requires that there be no room for error in operations. As technology increases drilling conditions, going to HPHT formations and deeper waters, traditional teaching techniques are starting to struggle. Textbooks and slide presentations can no longer adequately teach about the physics involved in today’s drilling technologies. Even though digital media…
Reservoir simulation has come to be the backbone of investment operations for current development projects in the oil and gas sector. Reservoir simulation works by converting the intricate mechanical data in the field into a mathematical equation model capable of predicting multi-phase flow behavior and EOR schemes before spending.This blog outlines some of the key…
The main cause of Non-Productive Time (NPT) and pipe sticking is wellbore instability, which is among the key causes of such losses. Given that drilling fluids act as the first line of defense when it comes to dealing with complex pressure conditions underground, they play an important part in wellbore stability. The following guide provides…
Floating oil rigs are offshore structures that stay buoyant while also supporting drilling and production tasks in the sea. Well, unlike fixed platforms that are anchored right to the seabed, floating rigs are set up to work in very deep water, where normal structures can’t be economically or technically put in place. In other words,…
The oil and gas industry has been shaped by operations that are complex, require high capital investment, and carry major safety and environmental risks. In recent years, though, the use of digital oilfield technologies has changed how oil production is managed, and this makes the daily work more efficient, safer, and also better on costs. Digital oilfield…
Workover operations are common practice for keeping mature oilfields productive. But doing a workover without proper data from the downhole environment means making expensive guesses. It is common practice in the industry to fail in workovers because wells are brought back into production showing the same water breakthrough, gas cone, or pressure problems. But the reason…
