Function Test On a 9 5/8 Inch PDM

(Positive Displacement Motor) drill bit assembly, the objective is to ensure that all downhole components — especially the PDM and bit — are functioning properly before drilling resumes. Here’s a breakdown of why the function test is important and how it’s performed: Perform a Function Test on a 9 5/8 inch PDM Drill Bit Function […]

Fracking Operation (Hydraulic Fracturing)

Hydraulic fracturing, commonly known as fracking, is a well stimulation technique used to extract oil and natural gas from deep underground formations, particularly from tight formations like shale, sandstone, and coal beds. The process involves injecting high-pressure fluid into the rock to create fractures, allowing hydrocarbons to flow more freely to the wellbore. Key Steps […]

Kick in Oil Well H2S Gas and Mixture of OIl

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

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

36 Inch Tricone Drill Bit

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 […]

Wireline Tractor

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. […]

Reviving Old Wells, the Smart Way

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 […]

Running 13.625 Casing

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 […]
