Abstract Downhole shocks and vibrations have been identified by many operators as one of the biggest causes Non-Productive Time, most significant factors limiting rate penetration (ROP) leading cause premature failure downhole tools. Today existing methods for detection characterization dynamics rely on costly sensors integrated in bottom hole assembly (BHA). This paper presents a new technique detecting characterizing drillstring shock real-time using solely surface measurements machine...
Abstract This paper presents a study of three cases in which release trapped torque occurs during the drill pipe connection process, leading to bottomhole assembly (BHA) damages. It highlights contributing factors and root causes events, it proposes prevention mitigation measures prevent these transient events. In recent years, industry has sought reduce times overall well construction cycle time. Over same period, upgraded high-performance motors aggressive bits are more capable trapping...
Summary In hole enlargement while drilling (HEWD) operations, underreamers are used extensively to enlarge the pilot hole. Reamer wipeout failure can cause additional bottomhole assembly (BHA) trips, which cost operators millions of dollars. Excessive reamer shock and vibration leading causes wipeout; therefore, careful monitoring is important in mitigating such a risk. Currently, downhole sensors dynamics simulations (DDSs) comprehend reduce vibration, but cannot be placed exactly at...
Abstract In the continuous pursuit of enhancing efficiency and safety drilling operations, optimized placement downhole sensors has emerged as a pivotal area innovation. This paper presents an configuration for sensor placement, meticulously designed to advance understanding control dynamics. By integrating high-resolution capable measuring three-axis acceleration, revolutions per minute, weight on bit (WOB), torque, approach monitor analyze system's performance can be established. The...
Abstract The highly productive Permian Basin requires wells with high dogleg severity (DLS) curve and long lateral sections. After many years of development participation by all major industry players, most 8.5in size are still being drilled using two bottomhole assemblies (BHAs); one for the a second extended section. This increases cost, time, risks. With our new solution, sections can now be consistently in run. Using in-house digital modeling dynamic drilling simulation software complete...
Abstract After 10 years of Brazilian presalt exploration and development, the carbonate reservoirs continue to pose drilling challenges, leading unwanted bottomhole assembly (BHA) trips due severe shock vibration, low rates penetration (ROP), premature drill-bit cutting structure damage. Today, industry efforts improve performance in carbonates are driven by trial error, which is very costly ultradeepwater environment. The adoption a collaborative mindset since 2012 between service provider...
