Successful Validation of Drillsoft Hydraulic Transient Simulator in a Deep-Water well

A successful validation of Drillsoft® transient well model was carried during the drilling operation in deep-water well in West Africa.  Using Pressure-While-Drilling (PWD – measurement of downhole annulus pressure and temperature) to compare the measured ECDs and static mud densities with hydraulic transient model predictions. This article present actual pressure and temperature data during drilling Continue reading

Coriolis Flow Meter

Get the Most of Coriolis Flow Meters. Improve Your Operations with This Advanced Diagnostics

Generally in MPD/UBD operations and drilling companies use devices to measure flow in and flow-Out. The most common device nowadays for flow_out is a Coriolis flow meter (mass flow meter), because this technology is reliable and offer measurements not only flow but density, temperature among others. There exist a variety of these Coriolis flow meters Continue reading

What exactly is transient and how is different from steady-state calculations?

The important effect of Temperature. Transient Temperature effect is very important in the accuracy of MPD/UBD calculations. Most people ignore this effect perhaps because they don’t have the right tools to calculate the transient effect, so many engineer just take the thermal gradient and use steady state formulas to calculate the bottom hole temperature. What Continue reading

Drillsoft has developed an ActiveX component that allow connect your own interface with our Hydraulic transient engine. This technology allows you design your own interface in any programing language. For instance, you don’t need to be MS-Excel expert to get a customize spreadsheet with tables and graphs. So you focus on your design how present Continue reading

Hole Cleaning Problems? See How Optimize Cuttings Transport and Drilling Hydraulics

Optimal Hole Cleaning Drilling fluid hydraulics and hole cleaning is an integral part of the practical processes required for planning and drilling a well. Optimization of cuttings transport depends on so many factors- hole angle, cutting size, drill string rotation, drill pipe eccentricity, optimization of bit hydraulics, ROP, hole cleaning pills, cuttings transport ratio, cuttings Continue reading
