To optimize drill string stability, several BHA options, combined with a detailed bit model, were analyzed in advanced Finite Element Analysis (FEA) drilling dynamic simulation. The process generated the most stable bit-BHA configuration, ROP-bit durability...

... The 17.5 in IADC 115 bit was used for the initial side load tests first at a set height, then with an ROP of 12 ft/hr (or about 5 minutes per foot vertical advance rate), bit rotary speed of 20 rpm, and side pull load of 500 to 1000 lb. Once the bit with these parameters was observed to behave...

These practices have also made a new record of the fastest well completion in 2.17 days and the highest drilling ROP for 141 m/hour with drilling...

... sizes. Key performance metrics include rate of penetration (ROP), rerun-ability, torsional response, and ability to maintain tool-face control during directional drilling. A high-performance drilling application was selected with several existing offset wells using a 12¼-in., five-bladed, 19-mm (519...
