Automation of surface equipment, dissolvable and shorter plugs push efficiency of fracturing operations

Terves’ Response Element DE 50 is a fully dissolvable polymer that is being used to make frac plugs.

Increasing use of water due to longer laterals and higher stage counts are also driving demand for more cost-effective water management solutions By Kelli Ainsworth, Associate Editor As operators push the number of stages per well to upwards of 75 or even 100 in some plays, they’re also demanding step-changes in the efficiency of hydraulic fracturing technologies and equipment, including associated technologies like water management systems. A significant area of focus has been on reducing plug mill-out time, with more dissolvable technologies coming to the market, as well as the development of shorter plugs with less material to mill through. Technologies are also emerging to automate the surface operations of hydraulic fracturing. While the industry has made significant progress in ...

IBP: Brazil is ‘on the right track’ with changes to local content, tax regimes, environmental licensing

IBP Secretary-General Milton Costa Filho expressed confidence that improvements will be coming soon to Brazil’s environmental licensing process. Technical engagements with IBAMA are helping the agency to understand how the E&P industry works and what its technical issues are, he said. “We are also bringing experience from other countries. Having benchmarks is very important,” he said.

It might be an understatement to say that the Brazilian oil and gas industry is in a state of flux. With the double whammy of a global oil price collapse and a corruption scandal that brought its national oil company to the brink of meltdown, Brazil looked like it was headed for some deeply troubling times...

Drill bit adapts depth-of-cut control to mitigate stick-slip, enhance ROP

Figure 1 shows an 8 3/4-in. prototype of the bit, with adjustable units installed. The bit mitigates vibrations by resisting rapid changes in depth-of-cut that occur during unfavorable dynamic events. This adjustment is accomplished through a passive hydro-mechanical feedback mechanism encapsulated in self-contained units that are installed inside the bit blades.

Mitigating vibrations during drilling remains a challenge for many fixed polycrystalline-diamond-compact (PDC) bits, particularly as drillers attempt to drill longer sections in a single bit run. Vibration arising from torsional stick-slip and impact loading in interbedded formation and transition can cause premature damage to a drill bit and other components in the bottomhole assembly (BHA) – ultimately hindering drilling performance....

Selective standardization approach could help industry sidestep market barriers, achieve full automation

Figure 4: An open-platform master control system with the ability to facilitate “plug & play” across equipment from different vendors is the single most significant enabler of drilling automation.

Drilling standardization, collaboration and automation have become major buzzwords in the industry in recent years, promising higher reliability, improved safety, increased efficiency and decreased costs. Due to the complexity associated with the automation of rig floor equipment, however, full automation of processes and equipment will not be possible until there is a higher level of collaboration and standardization...
