Drilling Rig: A drilling rig is a device used drill and Cement oil and gas well. The correct procedure for selecting and sizing a drilling rig is as follows: 1. Design the well 2. Establish the various load. 3. Compare the rating of existing rig with the design loads. 4. Select the appropriate rig and its component. Types of rig: 1. Land rigs 2. Offshore rigs There are two types of offshore rig: 1. Floating rig Semi-submersible Drill ship 2. Bottom supported rigs: There are three types: Jack ups Platform Barge Rig component sizing: 1. Hoisting 2. Rotating Equipment 3. Circulating system 4. Tubular Goods 5. Pressure control 6. Derrick capacity and substructure 7. Total power requirement for the above.

A rig structure typically refers to the framework and components of offshore oil drilling rigs or onshore drilling rigs. Key elements include: 1. Mast or Derrick: The tall structure that supports the drilling apparatus. 2. Drill Floor: The area where the drilling operations take place. 3. Substructure: The base that supports the rig and houses equipment. 4. Mud System: Manages drilling fluids to cool and lubricate the drill bit. 5. Power Systems: Generators and engines that provide energy. 6. Living Quarters: Accommodations for crew members. 7. Safety Equipment: Includes blowout preventers and emergency response gear. Each component plays a crucial role in ensuring efficient and safe drilling operations.

𝐥𝐞𝐭'𝐬 𝐠𝐨 𝐭𝐚𝐥𝐤 𝐚𝐛𝐨𝐮𝐭 𝐦𝐚𝐫𝐢𝐧𝐞 𝐫𝐢𝐬𝐞𝐫 𝐬𝐲𝐬𝐭𝐞𝐦 A marine riser system is a crucial component in offshore drilling operations. It's essentially a long, vertical pipe that connects the subsea wellhead to the drilling rig on the surface. This connection allows for the circulation of drilling fluids (mud) and the transmission of control signals between the rig and the wellhead.    𝐓𝐲𝐩𝐞𝐬 𝐨𝐟 𝐌𝐚𝐫𝐢𝐧𝐞 𝐑𝐢𝐬𝐞𝐫𝐬: 1.Drilling Risers: Used during the drilling phase of a well. They are designed to withstand high pressures and temperatures.  2.Production Risers: Used to transport hydrocarbons (oil and gas) from the subsea well to the production platform. They are designed for long-term service and may have additional features like corrosion protection. 𝐅𝐮𝐧𝐜𝐭𝐢𝐨𝐧𝐬 𝐨𝐟 𝐚 𝐌𝐚𝐫𝐢𝐧𝐞 𝐑𝐢𝐬𝐞𝐫 𝐒𝐲𝐬𝐭𝐞𝐦: 1.Circulation of Drilling Fluids: The riser allows the continuous circulation of drilling mud, which cools the drill bit, removes cuttings, and maintains wellbore pressure.  2.Well Control: The riser houses the control lines that allow the rig crew to operate the BOP and other well control equipment.  3.Structural Support: The riser provides structural support to the drill string, preventing it from buckling or collapsing under pressure. #oil #gas #pump #procesing #offshore #onshore #downhole #engineer #petroleum #subsea #sea #job #marine #EMS #SLb #egypt #production #rig #seabed #wellheadengineer #mser #Adnic #ADIBIC

Hoisting Rig Capacity When a drilling line is operated close to the minimum design factor, care should be taken that the rope and related equipment are in good operating condition. The force or overpull required to free a stuck drill string or release completion retrievable packer must be applied in addition to the load already supported by the drilling rig and the drill pipe. This combined force often exceeds the safe tensile strength of the drill pipe, and sometimes the hoisting capacity of the drilling rig. Remember that a spark becomes a flame if the right conditions happen, a flame eventually becomes embers if the wrong conditions happen. By sharing your field experience, state the main cause of the accident in that video below 👇 and define how to avoid its happening.

Well intervention can be categorized into three main types based on the level of complexity and the equipment required: 1. Light Well Intervention Performed without the use of a drilling rig, often using wireline or coiled tubing. Focuses on minor maintenance or data acquisition. Examples: Wireline logging for reservoir evaluation. Scale and wax removal. Setting or removing plugs. Well integrity checks and diagnostics. 2. Medium Well Intervention Uses coiled tubing or snubbing units, often requiring more specialized equipment. Can handle operations requiring fluid injection or light mechanical work. Examples: Acidizing for well stimulation. Sand cleanouts. Nitrogen lifting to restart production. Fishing operations to retrieve stuck tools. 3. Heavy Well Intervention Requires a drilling rig or a workover rig. Involves complex operations, often requiring significant downtime and cost. Examples: Tubing replacement or repair. Recompletion of the well to target new zones. Installation or replacement of packers and downhole safety valves. Well plugging and abandonment. Each type is chosen based on the well’s condition, the nature of the issue, and the required outcome.

The slip joint - A vital piece of equipment on the floating drilling rig. Its purpose is to compensate for the rig heave. Once the subsea BOP is landed, the slip joint is opened up/stroked out to about mid stroke. Well, hopefully about mid stroke! From that point on and until the BOP is disconnected, the slip joint is continuosly working in conjunction with the vessel heave. Through dual seals in the outer barrel (stationary part), it ensures fluid integrity from the riser while the inner barrel (moving part) is moving up and down. Once the slip joint is stroked out, the LMRP (top part of the subsea BOP) and associated riser is kept in tension to prevent riser buckling and to ensure that a disconnect can be initiated as intended, if needed. The actual tension is created from the tension ring, which is located on the outer barrel of the slip joint, through either tensioning wires or hydraulic cylinders. If it wasnt functioning, the subsea BOP and would continuously be exposed to high amounts of tension and compression. On top of the slip joint, the upper flex joint is located and compensates for any horizontal offset between the vessel and the subsea BOP. The upper flex joint is connected to the diverter just below the rotary housing. I hope you get a chance to work on the slip joint goose necks at some point! If you know, you know!

Anatomy of a Drilling Rig: Breaking Down the Essentials Have you ever wondered what makes a drilling rig function like a well-oiled machine? Here's a quick breakdown of its key components: 1️⃣ Derrick/Mast - The towering structure that holds the drilling equipment. It’s the backbone of the operation, designed to handle the enormous weight of drill pipes and tools. 2️⃣ Drill String - A series of connected pipes used to drill into the Earth’s surface. Think of it as the arm that does all the heavy lifting. 3️⃣ Drill Bit - The business end of the rig! This specialized tool cuts through rock and soil to reach oil or gas reservoirs. 4️⃣ Mud System - Ever heard of drilling mud? This vital fluid cools the drill bit, stabilizes the wellbore, and carries rock cuttings to the surface. 5️⃣ Power System - Engines and generators provide the power needed to keep the rig running. Without this, everything grinds to a halt. 6️⃣ Blowout Preventer (BOP) - A safety-critical component that prevents uncontrolled flow of fluids. It’s the rig's first line of defense against blowouts. Every component of a drilling rig has a role to play, working in harmony to ensure efficient and safe operations. 🌍🔧 #Drilling #OilAndGas #EnergyIndustry #KnowledgeSharing

While drilling a horizontal section with WBM, drill string stuck due to large pressure overbalance across depleted zone. Troubleshooting and analysis showed differential stuck as there was partial mud return and no string movement. SLB ARC tool showed deep invasion. Faced difficult time firing the jar while waiting for crude oil to be displaced. Crude was displaced and MW has been lowered then string got free. Displaced crude oil out and continue drilling to TD after increasing lubricant concentration.    Recommendations while drilling through depleted zones: 1. Minimize overbalance to the lowest. 2. Add suitable concentration of lubricant to the mud in directional sections. 3. Rig crew to minimize connection time and reciprocate string if possible. 4. Good communication and follow-up are required among rig teams, especially rig supervisor and DD / LWD engineers to analyze resistivity logs as early as possible. CC: Drilling and Mud Engineers for appropriate mud program. The possibility of having such a case with oil base is almost zero.
