A kick in oil and gas drilling is an unwanted influx of formation fluids (oil, gas, water, or a mixture) into the wellbore due to a pressure imbalance. When H₂S gas (hydrogen sulfide) and oil are part of this influx, it presents serious safety, environmental, and technical challenges. Here’s a detailed discussion: A kick occurs […]

Drilling Oilfield typically refers to the process of drilling wells to extract oil and gas from underground reservoirs in an oilfield. Here’s a concise overview of how oilfield drilling works

Is among the largest rotary drilling tools used in the petroleum industry. These massive bits are essential for drilling the uppermost sections of oil and gas wells, particularly during the spudding phase, where large-diameter holes are required to set conductor casings and establish well foundations. Key Features of a 36-Inch Tricone Drill BitDesign: Comprises three […]

In wireline logging operations, a tractor is a specialized conveyance tool used to push or pull logging tools in deviated or horizontal wells, where gravity alone cannot move the toolstring through the wellbore. Traditional wireline relies on gravity to lower tools into the well, but in highly deviated, horizontal, or extended-reach wells, this becomes ineffective. […]

Innovation doesn’t always mean high-tech. Sometimes, simple solutions bring big results. Here’s a clever method to clean out casing water and even help kickstart production in shallow oil wells — cost-effective, fast, and practical. This kind of field ingenuity deserves more recognition in our industry. Let’s keep sharing these smart solutions to improve efficiency across […]

Surface Casing: When used as surface casing, it isolates shallow formations and freshwater zones, and supports the wellhead.Intermediate Casing: In deeper wells, it can serve as an intermediate string to isolate problem zones (e.g., high pressure, lost circulation). Casing Running Procedure Challenges & MitigationsTight spots / ledges: Use reamers, centralizers, and casing shoes.Sticking risks: Monitor […]

The drawworks is a large winch located on the drill floor of a rig. It is used to raise and lower the drill string and other equipment into and out of the wellbore. Main Components: Functions:Hoisting and lowering the drill string, casing, and bottom hole assembly.Controlling weight on bit (WOB) during drilling.Working with the traveling […]

Is the process of removing crude oil from underground reservoirs so it can be refined and used. It involves several steps, technologies, and equipment, typically grouped into two main phases: primary extraction and secondary/tertiary recovery. Mechanisms include:Solution gas drive: Gas dissolved in oil expands and pushes oil up.Gas cap drive: Gas in a cap above […]

During the running in hole, we encountered a severely damaged pipe — visually confirmed as rotten, with significant structural degradation. Given the condition and to minimize risk of further breakage or fish becoming unrecoverable, we opted for the following recovery approach: Recommended Action:Tool Selection: If casing ID permits, deploy a TDog Overshot equipped with sufficient […]
