I would like to get a sense from the community about drilling and completion technologies and innovations (beyond extended reach, fracking etc.) that are likely to have the greatest impact on drilling performance in coming years. I was thinking in terms of e.g. rig automation, managed pressure drilling, casing while drilling. Any thoughts or views greatly appreciated.
During my active time, 1965 - 1999 we gave more thought to reducing downtime. Selecting drilling equipment such as unitized wellheads, segmented clamps, hydraulic nuts, drilling-with-stands, etc.
Another example was rock bit selection e.g. using RBI bits we never drilled faster but we always drilled cylindrical holes - not conical. So we didn´t have to ream and we had no fishing involved as the bit refused to go further so avoiding losing teeth, cones, bearings.
Drilling programs should avoid under-reaming and the intervals for coring should be spelled out.
Land rig movings should be carefully planned - using P.E.R.T. for instances... A spare set of mattings do wonders for speeding Land rig moves.
Rig automation was good for safety but did little for speed; it achieved consistency, mainly.
