Drilling is a fundamental operation in the oil and gas industry, so companies can tap underground reservoirs and pull out valuable hydrocarbons. As energy demand keeps rising and the easily accessible resources become less available, the industry has developed various drilling techniques to reach oil and gas reserves. Usually, people split it into two major categories,…
The multi-stage hydraulic fracturing operations for tight gas and shale gas cannot afford any mistakes. Under extremely high construction pressure, large sand volume, and complex chemical dosing systems, a momentary decision-making delay at the control console could lead to stuck drill pipes, casing deformation, or costly early sand removal accidents. Although pump delivery automation has made…
Natural gas remains a key element in the global energy transition. With advancements in offshore extraction technology, remote gas fields have become economically viable for development. The developers face a core strategic choice: floating liquefied natural gas (FLNG) or land-based LNG?Both need to cool the natural gas to -162℃ (-260℉) to facilitate storage and transportation….
Well control is one of the most critical aspects of drilling and well intervention. Because unexpected things like kicks, sudden pressure changes, equipment failures, or even loss of circulation can pop up fast, and if they are not spotted and managed properly, they can turn into a serious well control incident, like immediately. In those moments,…
Deepwater well intervention is one of the riskiest and most costly operations in offshore oil and gas extraction. At depths exceeding 1500 meters beneath the sea surface, operators need to perform precise mechanical operations and real-time cable logging through the underwater wellhead.Under these conditions, the daily rental cost of a semi-submersible drilling platform or a…
Ask any operator in the pipeline control room about the leak detection system (LDS), and what you are likely to hear is the same complaint: too many false alarms.When the pipeline switches between multiple products, or when the main pumping station suddenly reduces the flow rate, water shock waves and pressure fluctuations will occur within…
In high-risk oil and gas operations, drilling safety and well control training are of utmost importance. For decades, the industry has relied on physical classroom simulators to train operators to handle major risks such as blowouts and well surges. Nowadays, with the acceleration of digital transformation, cloud-based portable software solutions are emerging as a new option. Whether…
In the oil and gas industry, well control training and certification are kinda essential for making sure drilling and production stay safe. Like, well control isn’t something you can improvise. Two of the most recognized well control certification systems worldwide are the IADC WellSharp certification and the IWCF Well Control certification. Both of these programs…
A well blowout is one of the most dangerous and a bit complex emergencies that can happen in drilling operations. It usually shows up when the formation pressure in a well ends up higher than the pressure from the drilling mud and well control systems, then it causes an uncontrolled release of oil, gas, or formation…
Global oil and gas development is rapidly advancing towards the era of high-temperature, high-pressure (HPHT), deepwater, and ultra-long horizontal wells, resulting in a sharp increase in the demand for complex pressure-bearing operations. In such a high-risk environment, achieving wellbore integrity restoration without well shut-in requires even higher technical capabilities from the operations team. For a…
