Coiled tubing (CT) drilling technology offers significant advantages in terms of cost and efficiency for exploitations of unconventional oil and gas resources. However, the development of CT drilling technology is restricted by cuttings accumulation

The challenges found in geothermal well drilling have forced the industry to develop new significant cost effective, time savertechnologies to go for deeper geothermal resources beyond their traditional limits. To overcome these challenges, the new D

Lateral restrainers are traditionally provided in reinforced masonry (RM) walls to prevent the vertical steel bars from buckling. In the current version of the Australian Masonry Standards (AS 3700–2018), the use of lateral restrainers in RM walls

As one of the major functions of drilling mud is to maintain pressure inside a wellbore to avoid any invasion of unwanted high-pressure, this makes the determination of this pressure loss a very complicated task in the petroleum drilling industry. Th

One of the major tasks of monitoring production well operations is to determine bottom-hole flowing pressure. The overwhelming majority of wells in the Perm Krai are serviced using borehole pumps, which makes it difficult to take direct bottom-hole f

This study aims to analyze the effect of fin geometry on the thermal performance of longitudinally finned-tube horizontal latent heat thermal energy storage (LHTES) systems. The longitudinal fins with different fin heights, thickness, and numbers wer

To define technical specifications for artificial substitutes, it is necessary to model their mechanical behaviour. Here we studied the linear and nonlinear biphasic models for Nucleus Pulposus (NP) and Annulus Fibrosus (AF). The associated material

Wellbore instability is a frequent problem of shale drilling. Accurate calculation of surge-swab pressures in tripping processes is essential for wellbore pressure management to maintain wellbore stability. However, cutting plugs formed in shale hori

Drilling highly fractured formations, typically fractured carbonates, often experiences kick problems and severe losses of circulation, resulting in a high nonproductive time (NPT). Pressurized mud cap drilling (PMCD) is the most appropriate methodol

Precise calculation of gas temperature profile is the key to gas drilling design. It is traditionally assumed that the gas temperature distribution in the wellbore is equal to the formation temperature, without considering the influence of fluid flow
