... formation. The wrong decision to apply MPD in a reactive way leads to NPT, influxes, mud losses and increased risks. It is shown how the conventional procedures to drill and make the trips are replaced by tailored MPD procedures leading to successful results. The Client understands the high value...

... Abstract The process of making drill pipe connections is not only crucial in drill string integrity but also in assessing rigfloor safety. Almost 15% of recorded incidents in US onshore rigs occur due to improper make-up/tripping process as reported by IADC in 2015. Even with advances in pipe...

... drilling cost can be expressed as the sum of rig cost for making round trips, rig cost for drilling, and bit cost. It is further assumed that bit life is limited by bearing failure, that bit weight is not limited by considerations such as hole deviation, and that drilling hydraulics are adequate. Based...

... design. The single-trip abandonment approach can drastically reduce associated costs common in well abandonment campaigns, including rig time and support services that are involved in making multiple trips in and out of the well. With an average rig rate of USD 500,000 per day for floaters, USD 100,000...

... field that has its own perfect formula at the moment of drilling wells. Such was the case at the beginning of this campaign, where a very popular practice here in Ecuador was used, which was drilling 40 continuous hours before making a short trip to either the last casing point or the last wiped...

... and needs. The use of electric motors enabled quick adoption to the changing drilling conditions while making connections, tripping etc. The furnished MPD calculations and graphs that drillers could follow for applying required MPD choke pressures kept MPD adaption simpler. The modifications made...

..., and inefficient decision-making on tripping. A real-time data analytics application is developed aiming to provide actionable information to operation to expedite decision making process. A historical dataset of surface mechanics data and bit records is collected from 40 bit runs drilled in 2016 and early 2017...

... was to enlarge intervals that ranged from 850 mts to 1000 mts in one run. The BHA was experiencing high levels of shocks and vibrations that forced the operator to make additional trips to finish enlarging the section. These additional trips proved to be costly high with rig rates between $750,000-$1million USD...

... in the same application. After the curve sections the same BHA drilled into the long lateral section without making a trip between the curve and lateral sections. Several records were broken in some of these 14 wells, including 19% more daily footage than the previous record. Almost all these wells were also...

... by using spinner-based flow meters and other sensors, which require the tool to make multiple trips through the well section of interest (e.g. Chadwick and Whittaker, 2011; Zhu et al., 2013). There are several problems associated with this technology. First, the tool set may partially block production...

... while controlling tool-face. Use of PDC bits makes it even more difficult to control the toolface due to high reactive torque. This forces the operator to use rock bits with a high risk of loosing cones after relatively short intervals. To be on the safe side the operator has to make several trips...

... pressure change from well to another, the best option was to use while drilling Formation pressure testing that provide accurate formation pressure, help in real time mud weight control decision making & save trip time needed for wireline runs. The Potential operator cost efficiencies of acquiring...

... to make conditioning trips. This paper will show the results of more than 280 wells and over two million feet of hole drilled with casing over the last eight years. Comparisons will be made to conventional drilling methods in several of the areas where the technology has been applied. Elements of study...
