Numerical Modelling of Cuttings Transport with Foam in Inclined Wells
In this study, a 1-D transient state mechanistic model of cuttings transport with foam in inclined wells has been developed. The model is solved numerically to predict the optimum foam flow rate (liquid and gas rate) and rheological properties that would maximize cuttings transport efficiency in inclined wells. A detailed sensitivity analysis of the effect of gas and liquid flow rates, drilling...
متن کاملStudy on Cuttings Transport Efficiency Affected by Stabilizer’s Blade Shape in Vertical Wells
Effective cuttings transport means a better hole cleaning in drilling operations, which can increase the rate of penetration (ROP), and avoids pipe sticking, higher drag and torque problems. This paper aimed to analyze cuttings transport efficiency affected by different blade shapes of stabilizers, which is often overlooked in drilling. For this purpose, Eulerian multiphase flow model was used ...
متن کاملCuttings in 2D Revisited
Given n lines in the plane, a (1/r)-cutting is a subdivision of the plane into cells such that each cell intersects at most n/r lines. Cuttings are fundamental to the design of geometric divide-and-conquer algorithms and have numerous applications. Early suboptimal constructions of cuttings were given implicitly in the works by Megiddo and by Dyer in the 80s; simple randomized constructions wer...
متن کاملNitidulid Beetles in Sugarcane Cuttings
When cane cuttings that have failed to germinate are dug up and examined, they are frequently found to be infested with the larvae and adults of Nitidulid beetles which, consequently, are often accused of responsibility for such failure. As additional evidence against them is adduced the rapidity with which replants may become infested in fields in which a high population of the beetles has bee...
