Abstract:

He article states that based on the processing of field data, it was found that when drilling wells on the Apsheron Peninsula, the average densities of drilling fluids fluctuate significantly, and when cementing a well, the density of the cement slurry is higher than the density of the drilling fluids. Therefore, under certain conditions, the U-tube effect or free fall occurs – this is a phenomenon during cementing, which results in a temporary loss of control over the fluid velocity and pressure in the annular space. The free fall effect occurs when the cement slurry is pumped into a casing f

Abstract:

Recent advances in drilling technology have resulted in longer horizontal wells and have increased the complexity of well completion; the well intervention is becoming more challenging. Conventional techniques are no more adequate to access in long openhole horizontal sections when using coiled tubing to perform intervention works such as stimulations, logging and zonal isolation. This essay was created to assess the capability of a coiled tubing string to reach the desired depth in a projected long horizontal well.

Abstract:

Horizontal and multilateral oil and gas wells are used to maximise hydrocarbon recovery while reducing the required well count and associated costs. Presently, lateral lengths are designed using semi-quantitative methods. Guided by a desire to minimise the risk of poor well deliverability, the tendency is to design producing lengths longer than required, with the rationale that the well connects with sufficient hydrocarbon bearing reservoir to provide good deliverability. Drilling long producing lengths, however, is expensive and generates a higher risk of drilling and lifecycle (intervention

In parallel the model of needle puncture was investigated.

Sequencing construction vessel and drill rig activities, and aligning this sequence with availability of suitable vessels is often a major challenge on such projects.

_ The oil and gas industry will spend an estimated $400 billion this year, and the lion’s share—about 90%—will go toward keeping existing production flowing. That figure is a reminder that while new discoveries grab headlines, the heavy lifting in meeting global energy demand happens in the maintenance of aging wells. One of the central pillars of that effort is well intervention—an often underdiscussed but essential component of upstream engineering. And despite its importance, it remains an opaque domain, where both the costs and the outcomes can be as uncertain as the need for intervention

During drilling and logging, depth alignment of well logs acquired in the same borehole section at different times is a vital preprocessing step before any petrophysical analysis. Depth alignment requires high precision as depth misalignment between different log curve measurements can substantially suppress possible correlations between formation properties, leading to imprecise interpretation or even misinterpretation. Standard depth alignment involves cross correlation, which typically requires user intervention for reliability. To improve the depth alignment process, we apply deep-learning

Abstract:

Riser systems are integral components of the offshore developments used to recover oil and gas stored in the reservoirs below the earth’s oceans and seas. These riser systems are used in all facets of the development offshore process including exploration and exploitation wells completion/intervention, and production of the hydrocarbons. Their primary function is to facilitate the safe transportation of material, oil and gases between the seafloor oceans and seas and the marine platform. As the water depth increases, the working conditions of this system becomes challenging due to the complex

Abstract:

Cost reductions have become an essential response to lower oil and gas prices. Drilling rigs operate in distant and sometimes hostile environments, so relocating rig-based experts to remote control centres saves costs and improves health, safety and environment (HSE). Key staff can work in an improved environment and movements to-and-from the rig are fewer, lowering transport-related costs and risks. The offsite experts can apply their expertise to the operations of multiple drilling rigs from a single location. To make this a reality, data from thousands of sensors on the rig and from measure

Currently, most of the fields being put into development are characterized by a complex geological structure, both in terms of section and in terms of plan. The solution of all geological tasks, including such important ones as the preparation of exploration projects, operation and effective development management, is impossible without creating models that reflect the main features of the variability of target parameters. The construction of adequate models of objects with a complex structure requires the involvement of all available information. The accuracy of the geological model is mostly

Abstract:

Wellbore integrity is of paramount importance to subsurface resource extraction, energy storage, and hazardous waste disposal. We have developed a simple noninvasive technology for casing integrity screening, based on the continuity of electrical current flow. Applying low-frequency current to a wellhead, with a distant return electrode, produces a casing current dependent on the background formation and the properties and depth extent of the well casing. These currents in turn generate surface electrical fields that can be captured in a radial profile and can be used to analyze properties of
