Hybrid drill bit with recessed cutters, increased blade counts designed to dig beyond the curve

Since launching the original Kymera hybrid drill bit in 2011, Baker Hughes, a GE company, has been expanding the bit’s capabilities. The latest iteration, the Kymera Mach 4, was launched in early 2018 and has been designed to drill every section of the well at a high rate of penetration (ROP) with low wear and tear. BHGE increased the blade count on the bit, improving lateral stability and reducing damage and wear on the bit, Shelly Cory, Kymera Product Line Manager, explains in this video from 6 March at the 2018 IADC/SPE Drilling Conference in Fort Worth, Texas. She also discusses how new recessed cutters help improve cuttings evacuation and contribute to extended bit life. Further, she outlines how the bit has enabled increased ROPs and saved bit runs in Oman and the Permian...

Economics, additional value must be considered before deploying 3D printing

As additive manufacturing, or 3D printing, technologies evolve, the oil and gas drilling industry is increasingly exploring potential applications and benefits, such as less time to market and faster deployment of design changes. The technology can also be valuable when it comes to time-critical part replacements, said Dietmar Reicht, Head of Future Markets for the Special Steel Division at steel-based technology and capital goods group voetsalpine. Mr Reicht was among five panelists at the plenary session at the 2018 IADC/SPE Drilling Conference in Fort Worth, Texas, on 7 March. However, despite the many possible benefits, companies should only pursue 3D printing when it provides added value, he cautioned. Watch DC Managing Editor Linda Hsieh’s interview with Mr Reicht to learn more...

Shell addresses human factors, technology limits to deploy MPD on exploratory HPHT campaign

The first deployment of a managed pressure drilling (MPD) application in an exploratory high-pressure and high-temperature (HPHT) drilling campaign in the Niger Delta was truncated by a significant kick incident. The plan for the MPD deployment entailed drilling the HP interval with a bottomhole pressure (BHP) or set point that is equivalent to the maximum pore pressure prognosis...

Integration enables deepwater MPD solution with a single control system

Schlumberger has introduced the industry’s first complete deepwater MPD integrated solution that uses only one control system and requires fewer personnel to operate. The system features a riser joint – including a rotating control device (RCD), a slim-line annular blowout preventer and flow spool – that weighs just over 80,000 lb and measures 40-ft long, making it the shortest and lightest available on the market, according to Bas Liezenberg, DPM Deepwater Product Champion, M-I SWACO, a Schlumberger company. “Our goal was to reduce the total cost of ownership,” he said...

Digital solutions guide path to better accuracy in directional drilling

The global directional drilling services market has taken a big hit during this downturn. In terms of market value, directional drilling fell from $16.55 billion in 2014 to $10.95 billion in 2015, then shrank further in 2016 to just $6.71 billion. Most of these reductions were brought about by project cancellations in the low oil price environment, according to Rajashekar Lokam, Research Analyst at Mordor Intelligence...

MPD vs underbalanced drilling: 10 ways they differ in operational strategy and implementation

The petroleum drilling industry drills many well sections using some type of unconventional drilling technique (UDT). A drilling operation is a UDT if it does not follow the conventional drilling method as done in the majority of cases. Conventional drilling utilizes a single-phase drilling fluid, which works on the premise of keeping an overbalanced pressure at the sand face. It discourages influx from a reservoir while drilling or when drilling stops for any other operation. Conventional drilling is also an open-loop operation, where the returned fluid from the well is directed to a flowline that is open to atmosphere...

Drill bit innovations target major barriers to ROP, durability

Although a drill bit is but one component of a large and complex drilling system, it can have an outsized impact on the efficiency of a drilling operation. “While the amount of money spent on drill bits may be less than 1% of the total cost of the well, it can really be argued that no single component contributes more to the overall drilling performance,” said Wiley Long, Bits and Drilling Tools Product Champion at Smith Bits, a Schlumberger company...
