Understanding the behavior of Influxes in OBM and WBM (8/1/2018) - Many articles have been writing about this matter, some with high technical explanation other with complicated terminology; this time we like to simplify and explain it using simple terminology the complex behavior of influxes (gas kicks) in Oil-Based Mud (OBM) and Water based mud (WBM). In the video below you can see the differences side-by-side Continue reading
Understanding Torque & Drag: Concepts and Analysis (3/12/2018) - Introduction Why do we need to perform torque and drag analysis? Torque and drag removes superstition and reduces dependence on assumptions from well planning by taking into account all aspects of the plan from equipment specifications and formation properties. Changes made to specific components during planning is readily computed for the entire system. This allows Continue reading
Successful Validation of Drillsoft Hydraulic Transient Simulator in a Deep-Water well (1/15/2018) - 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
Find out what are the maximum pressures you can handle an influx safely. (10/7/2017) - Question: How do you know is the MPD Operation matrix is “safe”? RCD Limit: 450 psi LOT: 13 ppg Min Influx allowed while drilling: 2 Bls* Max Influx allowed while drilling: 5 Bls* * Data as per company’s polices Answer: Run IME and check safe influx values. The objective Influx management Envelope (IME) is determine Continue reading
What is a Code Signing Certificate? Why is important? (10/5/2017) - The code signing certificate acts as a digital signature, confirm the software author and guarantee that the code has not been altered or corrupted since it was signed. Eliminate “Unidentified Publisher” warnings. Code signing is widely used to protect software that is distributed over the Internet. Code signing does not alter it; it simply appends Continue reading
Get the Most of Coriolis Flow Meters. Improve Your Operations with This Advanced Diagnostics (10/4/2017) - 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
Drillsoft: Drilling Software & Automation (9/28/2017) - Drillsoft is a platform for hydraulic applications and simulators for Dynamic Pressure Drilling (MPD/UBD) or conventional drilling.
What exactly is transient and how is different from steady-state calculations? (9/26/2017) - 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
The Evolution of MPD Operation Matrix: IME (9/13/2017) - MPD operation matrix helps us to manage the risk when an influx is taken during MPD operations. In the MPD operation matrix influx’s sizes are limited to surface equipment and detection capabilities, whereas the Influx Management Envelope (IME) quantifies them and go one step further and validate the data with well control simulation software. Why? Continue reading
Unlock the potential of your MS-Excel using this Real-Time ActiveX Component. No programming skill required. (8/6/2017) - 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 (7/24/2017) - 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
Drillsoft HDX: Dynamic Pressure Drilling (7/16/2017) - Drillsoft HDX is REAL TIME Software that concentrates on drilling hydraulics and modeling wellbore pressures and temperatures during all phases of the drilling operation in extended-reach, highly deviated, horizontal and high temperature and high pressure (HTHP) wells. The simulator uses state of the art algorithms and provides the user with a wide range of modeling options. Continue reading
How We Incurred in Losses While Tripping!! Watch out (7/12/2017) - This video shows the Surge & Swab effect while tripping (RIH/POOH) and how we can incurred in losses even though the bottom ECD seems fine and still we are far from bottom fracture pressure/ECD. Don’t miss it!! This generally happens in “weaker” formations below the casing/liner shoe, so we need to pay special attention Continue reading
Another Interesting Effect of Surge & Swab While Circulating!!! (7/8/2017) - This video shows a simulation RIH and POOH continuously (e.g. Coiled tubing) and the surge and swab effect in a well.
Hydraulics Optimization (7/8/2017) - Sometimes Drilling engineers overlook this simple but important concept about hydraulic performance and optimization. We are not reinventing the wheel here, I’m just suggesting use your knowledge and apply it. The concept of Hydraulic Optimization is based on the best condition to clean the well is when the force provided by the jets is the Continue reading
Wait and Weight Method and Driller’s Method (6/3/2017) - Comparison between Wait and Weight Method and Driller’s Method. It’s very well-known and documented the pros and cons between these two methods, we show you the real or numeric quantification between them using both methods under the same conditions. In the video you will see a simulation of 10 barrels gas influx controlled using both Continue reading
