Drill Bit Balling

Factors Affecting Drill Bit Balling Up▪️Formation – Clay stone and shale has tendency to ball up the bit even though you use highly inhibitive water based mud or oil based mud. ▪️Weight On Bit – High weight on bit will have more chance to create this issue. ▪️Hydrostatic Pressure in Wellbore – High hydrostatic pressure […]

Frac Sand

Frac Sand is quartz sand material with high purity and durability, typically found in small, round grains. Frac sand is a crush-resistant material produced primarily for applications in petroleum and other industrial industries.The versatile sand material is a key agent in hydraulic fracturing for producing petroleum fluids like natural gas liquids and oil from base […]

Milling Before Running Casing

Surface testing a Section Mill before RIH to create a window inside a 9 5/8″ #casing, during a P&A program that has a micro annulus in the B-annulus. Mill is designed for milling tubular fish, cleaning a casing internal diameter before running a casing patch and suppressing the damaged parts of a casing. Mill can […]

Full Opening Safety Valve (TIW valve)

There are two types of stabbing valves that must be prepared for well control: Full Opening Safety Valve (TIW valve) and Inside BOP valve (Gray Valve) In other words, TIW valves are an essential part of any drilling operation. But what exactly is a TIW valve?➖Full Opening Safety Valves➖Benefits➖Optimal Use Cases for TIW Valves➖Inside BOP […]

Collet Running Tool (CRT)

The collet running tool (CRT) is a hydraulically released running tool that requires no rotation to be released from the liner, making it suitable for applications in high-inclination wells. The clutch and premium tool joint connections permit high-torque rotating and drilldown capabilities throughout the liner system. When a rotational liner hanger is deployed, the CRT […]

Mud Balance Tester

Used to determine density of the drilling fluid. The instrument consists of a constant volume cup with a lever arm and rider calibrated to read directly the density of the fluid in ppg (water 8.33), pcf (water 62.4), specific gravity (water = 1.0) and pressure gradient in psi/1000 ft. (water 433 psi/1000 ft.) Calibration Test […]
