Raising and lowering the mast of a drilling rig involves several critical steps to ensure safety and efficiency. Here’s a detailed overview of the procedures: Raising the Mast 1. Preparation: - Warm up the engines and ensure there is sufficient fuel. - Check brakes, pins, and shoes. Burn brakes if there is oil on them. - Ensure no material is under the mast leg at the foot to prevent twisting. 2. Initial Setup: - Secure the drawworks skid to the substructure or a nearby heavy object to prevent overbalancing. - Check all toggles, cables, and grease all sheaves for free movement. 3. Raising Process: - Use the drawworks and a special hoisting cable to lift the mast from a horizontal to a vertical position. - Keep the crown end of the mast level with the substructure to reduce strain during the initial lift. - Ensure the deadline is tied down and secured with adequate clamps. 4. Safety Checks: - Perform a complete visual check of the mast for loose bolts, tools, or debris. - Ensure all rig floor winch lines and tong hanger lines are secure to prevent tangling². - Keep personnel at a safe distance from the rig floor and mast during the raising process. 5. Final Positioning: - Use a snubline to set the mast into its final position gently to avoid excessive vibration. - Secure the mast to the “A” frame and ensure all pins are in place before use. Lowering the Mast 1. Preparation: - Attach snub lines to a heavy truck. - String raising lines through sheaves in the mast side frames. 2. Lowering Process: - Unpin lifting frames from the mast side frames. - Ensure no tension on the bridle line. - Use a heavy truck to start lowering the mast gradually. 3. Safety Measures: - Release the line from the truck and continue lowering the mast using the drawworks. - Ensure all personnel are at a safe distance and no one is under the mast or substructure. These procedures are crucial for maintaining the structural integrity of the rig and ensuring the safety of the crew.

𝐋e𝐭'𝐬 𝐠𝐨 𝐭𝐚𝐥𝐤 𝐚𝐛𝐨𝐮𝐭 𝐓𝐡𝐞 𝐅𝐚𝐬𝐭𝐞𝐬𝐭 𝐖𝐚𝐲 𝐓𝐨 𝐋𝐚𝐲 𝐃𝐨𝐰𝐧 𝐃𝐫𝐢𝐥𝐥 𝐏𝐢𝐩𝐞𝐬 Down drill pipes from a rig to a catwalk typically involves a specialized piece of machinery called a drilling rig catwalk or pipe handling machine.  𝐁𝐫𝐞𝐚𝐤𝐝𝐨𝐰𝐧 𝐨𝐟 𝐭𝐡𝐞 𝐩𝐫𝐨𝐜𝐞𝐬𝐬 1.Preparation: The drill pipe is positioned on the drill floor (working area of the rig) near the V-door (a large opening on the side of the rig). The catwalk operator ensures the catwalk system is ready to receive the pipe. 2.Lifting and Transfer: The drilling rig catwalk utilizes a hydraulic arm or lifting mechanism to pick the drill pipe from the drill floor. This arm can be telescopic, allowing it to reach the pipe at various positions. 3. stabilizing and Moving: Once lifted, the catwalk arm maneuvers the drill pipe horizontally towards the catwalk. The arm might also have features like skateboards or kickers to help position the pipe precisely on the catwalk trough (a dedicated track on the catwalk). 4. Lowering and Alignment: The catwalk carefully lowers the drill pipe onto the catwalk trough, ensuring proper alignment. Some systems might have automated features to guide the pipe into the correct position. 5. Transportation and Storage: The catwalk system, with the drill pipe secured on the trough, can then move along the rig to the desired location, such as the well center or "mouse hole" (an opening near the wellhead). The pipe can then be lowered and stored on the catwalk until needed for the drilling process. #oil #gas #pipe #rig #drilling #pump #drillingrig #𝐃𝐨𝐰𝐧 #production #well #intervention #job #process #Egypt #onshore #safety #health #pass #offshore #downhole #down

#SafetySpotlight Repost Ahmed Shoukry The video below is a typical example of an incident that can occur during a Run In Hole (RIH) - a dropped casing liner on hand What happened? After a RIH 35 Joints of a 7-inch liner, the driller picked up the liner hanger assembly from the pipe rack using the crane to the rig floor and latched it to the elevators. The liner hanger engineer installed the liner wiper plug on the running tool, tightened and dropped it . The Injured person was positioned to align the hanger assembly with the center of the well into the 7-inch. However, during the process, the liner hanger assembly suddenly dropped down from the running tool, resulting in the amputation of the left hand above the wrist. Musing Time; 🤔 🤔 What should be the immediate course of action should an incident like this occur on a rig? Could this incident have been avoided?

COILED TUBING LIFTING FRAME OPERATION When it comes to CT operations offshore from a #drillship or #semisubmersible rig, a lifting frame plays a crucial role. Its function is to provide a motion-compensated connection for assembling the injector head and pressure control equipment. The bottom connection of the frame is usually linked to a temporary flowhead using a load-bearing hydraulic connector for efficient rigging processes. The handling sub of the lifting frame is secured in the rig traveling block elevators. On these rigs, a motion-compensating device is installed on either the traveling block or crown block to counter the wave action and heave on floating vessels. The tension in the tubing string serves as the anchor for the motion-compensation system to operate effectively. #oilandgas #offshoreoperations #liftingframe #CToperations #drillship #semisubmersible

DHVI Video Quadruple Montage!  This months Video is a compilation of wellbore obstructions providing examples from our high-resolution HD, wide field of view cameras, that were deployed to quickly assess some various reasons for BHA holdup.    In the first example the Capture Live HD Camera was pumped down 4 ½” inch casing into the horizontal section on wireline and identified a casing collapse as the cause of the BHA hold up. The casing collapse runs along the 2 o’clock to 8 o’clock plain of the wellbore and was live streamed in real-time to the client’s office for immediate next steps planning.   For the next example the client encountered an obstruction while doing some routine slickline work.   The camera was deployed in real-time on wireline down the tubing and was determined that the tubing had parted, and the lower section had now dropped causing the wireline BHA to tag out on the top of the lower parted tubing section. The camera was able to confirm that the production casing condition was good through parted interval.   The next example was from a drilling rig operation while performing the wellbore completion program.  The camera was pumped down drill pipe with clear filtered pond water and was determined that a anti-rotation key on the low side of the liner top had been bent in slightly causing the planned completion BHA to hang up.   In the final example the client encountered an obstruction while re-entering a newly acquired well.  Damaged and collapsed tubing was found to be the cause of the blockage. Whether your wellbore contains gas or liquids, or a combination of both, DHVI’s high resolution cameras, calipers and other logging sensors will provide immediate insight into your challenges at hand, live streamed to your office in real-time! Let us know how we can help with your wellbore challenges! For more information and other great case studies, visit www.dhvi.net. #downholetools #downholevideo

There are two drive systems used on rotary drilling rig. These are Kelly drive and top drive system. In this post we will go through of kelly drive versus top drive system. Top drive system is also known as TDS: In kelly system, Rotary table provide rotation. Whereas in TDS, String is rotated with TDS motor. Kelly drive is Cheaper but also slow, inefficient and unsafe. Whereas. Top drive system is Expensive but Fast, efficient, and safe. Kelly drive system is capable to drill with one single drill pipe. On other hand TDS is capable to drill with drill pipe stand. One drill pipe stand is made of three drill pipe joints together. While tripping if needs back reaming & circulation, need to Pick up kelly with swivel from rat hole and connect with string.Its very convenient to connect TDS and back ream with circulation at any point. Kelly Take longer time to make connection. TDS take less time to make connection. For tripping, Kelly must be rack back with swivel in rate hole on rig floor. TDS keep hanging all time with travelling block & hook while tripping. Kelly is old drive system. Whereas TDS is new drive system. Kelly is not round pipe reduce life of BOP rubber element. In TDS drill pipe are completely round, better for BOP element. Kelly need two case hole on rig floor, Rate hole & mouse hole. In case of TDS we need only mouse hole on rig floor. In Kelly system crew have to operate elevator manually, so less safety for rig crew. TDS have hydraulic system to move links and elevator, so TDS have more safety. In Kelly drive, bit is off bottom equivalent to Kelly length when connect another pipe for drilling. In TDS system bit almost on bottom, when make new drill pipe stand. #drilling #petroleumengineering #oilindustry
