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 […]

BHA Operation
This is a really crazy BHA trip operation. The well is not static and from what I see and can guess it wasn’t static for a long time, because if they arrived at the BHA and found themselves in those conditions something didn’t go as it should have. Fortunately, this no longer happen. They have […]
Coiled Tubing Kickoff
A coiled tubing kickoff typically refers to the process of using coiled tubing (CT) to initiate or assist in the drilling of a new wellbore or sidetrack. This method is often used in directional drilling, well interventions, and re-entry operations. Key Steps in a Coiled Tubing Kickoff:1.Pre-Job Planning & Design:Assess well conditions and objectives.Select appropriate […]
Coiled Tubing Operations Manual
The global oil and gas industry is using coiled tubing for an ever-increasing array of well intervention projects. Coiled tubing offers a number of operational and economic advantages, including: live well intervention, elimination of well kill and potentially damaging heavy-weight kill fluids, reduced operational footprint, horizontal intervention, and the ability to intervene without a rig. […]
Schlumberger Dowell Coiled Tubing Client School Manual
This manual has been prepared to complement the information provided through the presentations and discussions held during a Schlumberger Dowell Coiled Tubing Client School. The technical information within this manual is intended to provide a basic understanding of the equipment, tools, processes and design requirements associated with modern coiled tubing operations. Comprehensive and detailed information, […]
Coiled Tubing Connectors
Selecting the appropriate connector is generally dependent on the application and operator preference.Grapple connectorSetscrew/dimple connectorRoll-on connector 1.Roll-On ConnectorThe roll-on connector attaches to the internal diameter of the CT and is held in place by crimping the CT around a connector profile with a special crimping tool. However, the roll-on connector poses a significant obstruction to […]
Flowback Coiled Tubing
In a coiled tubing (CT) operation, flowback refers to the return of fluids (such as wellbore fluids, treatment fluids, or reservoir fluids) to the surface after pumping stops. If the flow rate during flowback is very low, several factors could be responsible: 1. Reservoir Pressure is Low – If the reservoir has low energy, it […]
Shale Shakers
Shale shakers are components of drilling equipment used in many industries, such as coal cleaning, mining, oil and gas drilling.They are the first phase of a solids control system on a drilling rig, and are used to remove large solids (cuttings) from the drilling fluid (“mud”). Typical shale shakers on a drilling rigDrilling fluids are […]

Coiled Tubing String
A coiled tubing string is a continuous, flexible steel or composite pipe wound on a large spool. It is used in oil and gas operations for various well intervention, completion, and drilling tasks without the need for a conventional drill pipe or workover rig. Key Features:Made of high-strength, low-alloy steel or composite materials.Available in different […]
