Drilling Capability Tolerance Chart Pilot Holes and Field Matching Drilling Aluminum and Steel To make a fastener hole of the correct size, first drill a hole slightly undersize. This is known as predrilling, and the hole is called a pilot hole. Ream the pilot hole with a twist drill of th...
A method and apparatus for drilling a hole through a first part (110) and a second part (112). An image of a first pilot hole (114) in the first part is generated using an imaging system (132). A first feature related to the first pilot hole in the first part is identified based...

Avoid Pilot Holes, Land Wells and Optimize Well Placement and Production with Deep Directional Resistivity Logging-While-Drilling 已发表: 04/02/2014 Premium Landing horizontal wells in a reservoir is a critical task, and the accuracy of the result drives the economics of a well. THIS ITEM IS...
In some parts of the Eastern US, where small slim holes are common, 10 ft of fill on a trip would be considered poor hole cleaning. On the other hand, the same 10 ft of fill in a deep large hole in the Western US or Canada might be considered good hole cleaning (Maurer Engineering...
Drill-bit seismic signal of the vertical geophones in Well 1 obtained during a drilling test with a downhole-pilot tool and wired-pipe telemetry. Traces are plotted versus receiver elevation, the free-surface is at 257 m elevation. The drill-bit source is at 284 m depth (corresponding to...
Precision and accuracy: The diamond drill bit has excellent precision and can drill holes precisely without cracking or damaging the surrounding granite. Versatility: In addition to granite, diamond bits can also be used to drill through other hard surfaces such as porcelain, tile, and marble. Thi...
using a step-down chart in accordance with the Engineers Method. The circulation will cause the influx570to migrate to a position that is no longer near the BHA558. This may increase the annular area near the influx570, thereby reducing its vertical height to H2, as shown in FIG. 5C. Th...
Oil or synthetic fluid-based muds are normally used to drill swelling or sloughing shales, salt, gypsum, anhydrite or other evaporate formations, hydrogen sulfide-containing formations, and hot (greater than about 300 degrees Fahrenheit (“° F.”) holes, but may be used in other holes penetrat...
