❇️Coil Tubing Drilling (CTD) is a drilling technique that uses continuous coiled tubing instead of conventional jointed drill pipe. Here's an overview: Key Features: 1. Continuous Operation: Coil tubing is a continuous pipe spooled on a large reel, which eliminates the need for making and breaking connections, resulting in faster tripping times. 2. Flexibility: The coiled tubing can be bent to pass through smaller wellbore restrictions, making it suitable for workovers, sidetracking, and drilling in complex well trajectories. 3. Reduced Footprint: The equipment for CTD generally occupies less space than conventional drilling rigs, making it suitable for offshore and environmentally sensitive areas. 4. Circulation While Tripping: Fluid circulation can be maintained during tripping operations, enhancing well control and allowing for continuous removal of cuttings. Applications: - Wellbore Cleanouts: Removing debris, sand, or fill from the wellbore. - Fishing Operations: Retrieving lost or stuck equipment from the well. - Underbalanced Drilling: Drilling with the wellbore pressure lower than the formation pressure to minimize formation damage and increase reservoir performance. - Sidetracking: Creating a new wellbore trajectory from an existing well to access untapped reserves. - Thru-Tubing Drilling: Drilling new sections of the well without removing existing production tubing. Advantages: - Increased Safety: Reduced need for manual handling of drill pipe. - Faster Operations: Continuous pipe allows for faster tripping in and out of the hole. - Enhanced Well Control: Ability to circulate fluids continuously during operations. - Reduced Environmental Impact: Smaller rig footprint and lower noise level Limitations: - Depth Limitations: The tensile strength of the coiled tubing limits the maximum depth. - Fatigue Issues: Coiled tubing is subject to cyclic bending, which can lead to metal fatigue. - Limited Bore Size: Generally suitable for smaller boreholes, which may limit its use in large-diameter wells. Equipment: - Coiled Tubing Unit: Includes the reel, injector head, and control cabin. - Bottom Hole Assembly (BHA): Includes the drill bit, mud motor, and measurement tools. - Well Control Equipment: Blowout preventers and other safety devices. Process: 1. Planning: Design the well trajectory and BHA configuration. 2. Mobilization: Transport and set up the coiled tubing unit on-site. 3. Drilling: Use the coiled tubing to drill the well, continuously circulating fluids to manage cuttings and pressure. 4. Completion: Once drilling is complete, the well is completed with appropriate casing and production equipment. CTD is an efficient and versatile method, especially in scenarios where conventional drilling methods might be less effective or more costly.

🎥Tripping with the DDM Tripping pipe is the process of removing and / or replacing pipe from the well, with the derrick drilling machine (DDM) and iron roughneck work together, pulling and breaking connections with precision and efficiency. This 250x25 process requires minimal human by intervention, making it safer and more efficient for our crew. 🔗@Drilling

An Overview of Design, Analysis, Construction and Installation of Offshore Petroleum Platforms Suitable for Cyprus Oil/Gas Fields Offshore structures are used worldwide for a variety of functions and in a variety of water depths, and environments. Since right selection of equipment, types of platforms and method of drilling and also right planning, design, fabrication, transportation, installation and commissioning of petroleum platforms, considering the water depth and environment conditions are very important, this paper will present a general overview of these aspects. This paper reviews the fundamentals behind all types of offshore structures (fixed or floating) and, in the case of fixed platforms, will cover applications of these principles. The overall objective is to provide a general understanding of different stages of design, construction, loadout, transportation and installation of offshore platforms. Finally, for different sea-water depths, in which the Cyprus platforms are intended to be installed, suitable kinds of offshore platforms are proposed
