Some additional details about wireline drilling:
Wireline Tools: Wireline drilling involves the use of various tools and instruments that are deployed downhole through the wireline drilling pipe. Some common wireline tools include:
Logging Tools: Logging tools are used to measure and record various properties of the subsurface formations. These tools can include instruments for measuring formation resistivity, natural gamma radiation, acoustic properties, formation pressure, and fluid saturation. Logging data helps geologists and engineers evaluate the potential productivity of the reservoir and make informed decisions regarding well completion and production strategies.
Sampling Tools: Wireline sampling tools are designed to collect fluid or solid samples from the formation. For example, wireline formation testers can be used to capture fluid samples and measure their properties, such as pressure, composition, and flow rates. Core barrels and coring tools can be used to extract solid core samples for detailed analysis.
Perforation Tools: Perforation tools are used to create holes or perforations in the well casing and surrounding formation to facilitate the flow of hydrocarbons into the wellbore. These tools are commonly used in wireline operations to enhance well productivity and allow for reservoir stimulation techniques, such as hydraulic fracturing.
Imaging Tools: Wireline imaging tools provide detailed visual information about the subsurface formations. For example, borehole imaging tools use cameras or sensors to capture images of the wellbore walls, allowing geologists to identify and characterize various geological features, such as fractures, bedding planes, and formation dip angles.
Wireline Data Acquisition: Wireline drilling allows for real-time data acquisition from downhole tools, which provides valuable information for decision-making during drilling operations. The wireline cable serves as the conduit for transmitting data from the downhole tools to the surface. This data can include measurements of formation properties, imaging data, and other relevant parameters. Real-time data acquisition enables drilling operators to make adjustments to drilling parameters, optimize well placement, and mitigate drilling risks.
Wireline vs. Drill Pipe: Wireline drilling pipe differs from traditional drill pipe used in rotary drilling. While drill pipe is primarily used for rotary drilling methods, wireline drilling pipe is specifically designed for wireline operations. The key differences between wireline drilling pipe and drill pipe include:
Construction: Wireline drilling pipe is typically thinner and lighter compared to drill pipe. It is designed to be easily spooled onto the winch drum and run through the wireline sheave wheel.
Functionality: Wireline drilling pipe is primarily used for deploying and retrieving downhole tools, collecting core samples, and conducting wireline operations such as logging and testing. Drill pipe, on the other hand, is used for the rotation and circulation of drilling fluid during the drilling process.
Continuous Sampling: One of the significant advantages of wireline drilling is its ability to collect continuous core samples. Unlike conventional drilling methods that retrieve intermittent core samples through the drill pipe, wireline drilling allows for continuous coring, resulting in more comprehensive and representative core samples.
Wireline Operations and Services: Wireline drilling services are provided by specialized companies that offer a range of wireline operations, including:
Core Drilling: Wireline drilling companies offer core drilling services for geological and geotechnical investigations. This involves using wireline drilling pipe and core barrels to extract core samples from the subsurface formations. The core samples are then analyzed to gain insights into the rock properties, mineral composition, and reservoir characteristics.
Logging and Formation Testing: Wireline service providers offer logging and formation testing services using advanced wireline tools. These services involve deploying logging tools downhole to measure and record various formation properties, such as resistivity, porosity, permeability, and formation pressure. Formation testing services involve evaluating reservoir properties and fluid characteristics through downhole sampling and analysis.
Well Intervention: Wireline operations are often used for well intervention purposes. This includes activities such as well cleanout, wellbore stimulation, plug setting and retrieval, and equipment installation or removal. Wireline tools and techniques allow for efficient and precise intervention operations, minimizing downtime and maximizing well productivity.
Data Analysis and Interpretation: Wireline service providers also offer data analysis and interpretation services. The collected wireline data, such as logging measurements, core analysis results, and formation testing data, are analyzed to provide valuable insights into reservoir properties, well performance, and production optimization strategies.
Wireline drilling and the associated services play a crucial role in the exploration, development, and production of oil, gas, and mineral resources. The ability to collect continuous core samples, perform real-time logging, and conduct formation testing helps operators make informed decisions throughout the drilling process, leading to improved well performance and resource recovery.

FAQ:
Q1: What are typical drilling fluid maintenance procedures?
Examples include monitoring properties, fluid contamination testing, fluid volume/chemical additive control, maintenance of solids control equipment, managing drill cuttings/solid migrations over time, and tailored additive treatments.
Q2: What key parameters are recorded in drilling reports?
Depth drilled, lithology, mud properties, casing details, survey data, corrosion/integrity tests, gas shows, fluid losses, drilling hours, non-productive time events provide a permanent well record.
Q3: What are the advantages of managed pressure drilling?
MPD uses downhole instrumentation and annular pressure control to improve wellbore stability, drill pressure-sensitive formations more safely, and optimize downhole hydraulics versus conventional methods.
Q4: When is underreaming applied?
Underreaming is used to efficiently drill lateral boreholes below tight shale or sand sections to prevent pipe from getting stuck when pulling out of the hole later. It involves drilling a intentionally wider hole below standard bit size.
Q5: What are common rotary steerable systems?
Examples include rotary steerable turbines (RST), push-the-bit, point-the-bit, and shaft-style RSS technologies attached to the bottomhole assembly which can steerable drill wellbores through bent motors or differential pressing/bending.
