Protecting the surface formations is very important to avoid facing any problems when drilling ahead to reservoir. The surface casing is cemented following a special procedure. It is cemented using the stinger which is made up on drill pipe and run to the surface casing shoe. The success of the operation is related to many […]

Rigging Up Workover Oil Well
Pre-job planning should be done to determine the safest and most efficient means to do the job. Once the rig move planning has been carried out, a pre-job meeting with all involved should be held. The following safety tips should be observed when rigging up/down a drilling rig. 🔹When determining the direction of setting up […]
Cement Head Leaking
The cement head provides the connection between the discharge line from the cement unit and the top of the casing. This equipment is designed to hold the cement plugs used in the conventional primary cementing job. The cement head makes it possible to release the bottom cementing plug, mix and pump down the calculated cement […]
Drilling The Oil Well
Spud the Well:After the rig has been inspected and all of the systems tested the well can be Spudded. Spudding a Well refers to starting the rotary drilling operations for that well. Drill Down to the Surface Casing Depth:The first section of the well to be drilled is the section that goes down to the […]
Lockdown Screw (LDS)
Lockdown screws, (LDS) utilize an external thread (ET) design that moves the threads outside the pressurized or wetted surface of the wellhead equipment. They utilize a robust Unified National Coarse (UNC) thread for the lockdown screw itself and the packing gland nut to minimize any galling. Additionally a one piece HBNR compression packing element with […]
Bottomhole Assembly (BHA)
Short for Bottom Hole Assembly, is a crucial component in oil and gas drilling operations. It acts as the interface between the drill string and the wellbore, playing a pivotal role in efficiently extracting hydrocarbons. BHA Is a specialized assembly of tools used in oil and gas drilling operations. It is connected to the drill […]
Casing Scraper for Well Drilling
The Casing Scraper is used to clean cement, mud, embedded bullets, rust, mill scale, paraffin, perforation burrs and other substances from the inside walls of casing. Maintaining a clean casing I. D. is important to the operation of all tools used in drilling the well. Likewise, packers and similar tools must have a clean surface […]
Drawwork Introduction
Drawwork is a critical component responsible for hoisting and lowering drill strings, casing, and other equipment during drilling and well completion operations. This powerful mechanism is the link between the wellbore and the surface, enabling the essential task of extracting and inserting materials at depth. Unraveling the Draw Works: A Deeper LookEssentially, the Draw Works […]
What Is Backflow?
Backflow from the drill pipe is a normal occurrence when a connection is broken at the rig floor. Backflow can result from the density differential of warm (low density) surface water pumped down the pipe against cold (denser) water in the ocean, air that has been trapped during connections and pumped down the pipe, dense […]
BOP Testing Procedures
Use water to test BOP’s. The reason is that water has less compressibility than mud. Make up testing assembly and set in into a wellhead profile. Ensure that the casing valve must be left opened and there must be personnel monitoring the outlet of casing valve all time while testing. You must ensure that personnel […]
