Multilateral Wells Drilling Technology Full Guide - DRILLING MANUAL | #drilling_manual Multilateral drilling wells are a technology that allows for the drilling of multiple wellbores from a single wellbore. This technology has been in use since the 1920s but gained widespread popularity in the late 1980s with the advancements in directional drilling. In this drilling manual, we will explore the terminologies, classification system, and junction levels associated with multilateral wells. The terminologies used in multilateral drilling wells include laterals, wellbores, hole, level, casing, liner, production, multilaterals, joint, access, tubing, whipstock, pressure integrity, and more. These terms are essential to understand the various aspects of multilateral drilling. There are several reasons for drilling multilateral wells, with the primary one being the return on investment (ROI) for the operator. Multilaterals are more expensive to drill, so the production rates must be higher for a longer period of time to make it financially viable. Multilateral wells are most effective in low to moderate-permeability reservoirs and can be used in compartmentalized or heterogeneous reservoirs to increase production. However, the economics of multilaterals depend on factors such as the complexity of the multilateral and the cost of individual vertical or horizontal wells. The classification system for multilateral drilling wells is based on the type of junction used. The TAML (Technology Advancement of Multilateral drilling wells) categorizes multilaterals into six levels, with each level indicating an increase in complexity, cost, and associated risks. The different levels of junctions determine whether the main wellbore and laterals are cased or left open hole, which affects the reentry capabilities and production isolation.

𝗛𝗼𝗹𝗲 𝗣𝗮𝗰𝗸-𝗼𝗳𝗳/𝗕𝗿𝗶𝗱𝗴𝗲 𝗦𝘁𝗶𝗰𝗸𝗶𝗻𝗴: 𝗔 𝗗𝗲𝗲𝗽𝗲𝗿 𝗗𝗶𝘃𝗲 𝗶𝗻𝘁𝗼 𝗦𝗵𝗮𝗹𝗲 𝗜𝗻𝘀𝘁𝗮𝗯𝗶𝗹𝗶𝘁𝘆 In the fast-paced world of oil and gas drilling, getting stuck can mean significant delays and financial setbacks. One common culprit behind stuck pipe is hole pack-off/bridge sticking, which occurs when unwanted material becomes lodged in the open hole. In our previous blog post, we provided a high-level overview of this issue. Today, we'll delve deeper into a specific category: Shale Instability. Shale instability arises from the inherent weakness of shale formations. These formations can easily crumble and slough off when exposed to the drilling process, causing fragments to bridge the wellbore and impede pipe movement. Let's explore the different sub-groups of shale instability: • Geo-Pressurized Shale (Mechanically Stressed Shale): In these formations, high pore pressure exerts a strong force on the rock matrix, reducing its stability. • Hydro-Pressurized Shale (Mechanically Stressed Shale): Here, water trapped within the shale pores weakens the rock, making it more susceptible to collapse. • Overburden Stresses (Mechanically Stressed Shale): The weight of the rock layers above the shale formation can cause it to become compacted and unstable. • Tectonic Stresses (Mechanically Stressed Shale): Regional geological forces can put stress on the shale, increasing its likelihood of collapsing. 𝗥𝗶𝗴 𝗧𝗲𝗮𝗺 𝗜𝗻𝗱𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀: Experienced rig crews can often identify signs of impending shale instability. These include: • Increased drilling torque • Higher rates of penetration (ROP) while tripping pipe • Formation carvings returns 𝗣𝗿𝗲𝘃𝗲𝗻𝘁𝗶𝘃𝗲 𝗔𝗰𝘁𝗶𝗼𝗻𝘀: By recognizing the telltale signs and implementing appropriate measures, we can significantly reduce the risk of encountering shale instability. Here are some key preventive actions: • Utilizing wellbore strengthening techniques like casing and liners • Maintaining proper mud weight to counteract formation pressure • Optimizing drilling parameters to minimize formation disturbance Stay tuned for future Erigworld posts where we'll delve deeper into specific well control procedures and equipment!

Bit Selection For Drilling Oil & Gas Wells Guide & Hints - DRILLING MANUAL | #drilling_manual Bit selection is a critical aspect of drilling oil and gas wells, as it directly impacts the efficiency and success of the drilling operation. The right balance between durability and rate of penetration (ROP) must be achieved to ensure optimum performance. Selecting a bit that offers the desired balance can help avoid catastrophic failures and ensure the bit can maintain the gauge hole. Additionally, the chosen bit should be responsive to directional drilling requirements and have a cutting structure that can withstand variations in formation character and drilling parameters. Effective bit selection is an economic issue, as poor choices can result in increased costs. To guide the bit selection process, it is important to define the objective of the application and gather relevant data from similar applications. Analyzing actual performances of different bit types and assessing geological data can help establish a performance baseline. Various factors are considered in bit selection, including the lithology of the rocks being drilled, the directional demands placed on the bit, and the interval that the bit needs to drill. Other factors such as mud type and the need for reaming also play a role in the selection process. By considering these factors and evaluating the probable cost per foot, the most suitable bit can be chosen for the drilling operation.

Loss Circulation Drilling Classification & Types - DRILLING MANUAL | #drilling_manual Loss circulation is a common problem in drilling operations that refers to the loss of drilling mud into subsurface formations. This not only leads to high mud costs but also has various detrimental effects. When flow is reduced in the annulus above the loss, it can lower the carrying capacity of the mud and cause cuttings to accumulate, potentially leading to pipe sticking. Additionally, the loss of mud into the formation can lower the hydrostatic pressure in the wellbore, causing wellbore instability and the sloughing of shales. In extreme cases, loss of circulation can even result in a blowout if kick warning signs are ignored. Therefore, it is crucial to understand the types and causes of lost circulation, as well as how to assess and address these problems. There are several types of lost circulation zones that can occur while drilling. The first type is highly permeable formations, such as shell beds or gravel beds, where mud losses can be as high as 100% of the pumped volume. The second type is naturally fractured formations, which can result in a sudden loss of returns with no preceding gradual losses. Cavernous or vugular formations, created over geological periods by dissolved limestones, dolomites, or salts, can also cause immediate 100% loss of returns. Lastly, induced fractures due to a pressure imbalance during drilling operations are the most common type of lost circulation and can occur at any depth. Understanding the characteristics and signs of each type is essential for proper diagnosis and remediation. When faced with lost circulation in drilling operations, it is important to classify the losses correctly in order to determine the appropriate treatment. Losses can be categorized as seepage losses, partial losses, severe losses, or complete losses. Seepage losses occur slowly and may be difficult to identify, while partial losses require the addition of lost-circulation material to slow down the losses. Severe losses involve the rapid loss of large volumes of drilling mud, which can lead to well control issues and hole stability problems. Complete losses, where there are no returns at all, require refilling the annulus with lighter mud or water to maintain hydrostatic pressure. Assessing and reporting lost circulation events accurately is crucial for determining the best course of action and preventing further complications. For a more comprehensive understanding of loss circulation drilling, including the causes, remedial actions, and preventive measures, it is recommended to read the full article at https://lnkd.in/d6CyBN9E.
