Improved Bottomhole Pressure Control for Underbalanced Drilling Operations

Abstract: fax 01-972-952-9435. AbstractMaintaining underbalanced conditions from the beginning to the end of the drilling process is necessary to guarantee that underbalanced drilling (UBD) operations successfully avoid formation damage and potential hazardous drilling problems such as lost circulation and differential sticking. However, maintaining these conditions during operations with jointedpipe is an unmet challenge that continues motivating not only research but also technological developments.This paper proposes… Show more

“…A mechanistic approach for finding correlations, which considers the annular geometry and upward flow encountered in drilling, was developed by ; ; Lage and Time (2002), which uses 5 different flow patterns Bubble, Slug, Churn, Annular and dispersed bubble. This approach was further studied by Perez-Tellez (2003); Perez-Tellez et al (2003) and employed on Iranian field data by Ashena and Moghadasi (2010).…”

“…These pressures are called geopressures. Geopressures properties allow the casing shoe depth determination, in which its lower limit is determined by the gradient pores curve, and its upper limit corresponds to the fracture gradient (Lyons et al, 2015).…”
