Drilling
Developing the theory of mechanical specific energy from the perspective of instantaneous drilling power rather than the compressive strength of the formation leads to an improved understanding of drill-bit mechanical efficiency.
The oilfield service company will supply power plants capable of electrifying 180,000 US homes with geothermal energy.
This article is the fourth in a Q&A series from the SPE Research and Development Technical Section focusing on emerging energy technologies. In this piece, David Reid, the CTO and CMO for NOV, discusses the evolution and current state of automated drilling systems.

Utah FORGE has completed the first highly deviated, deep geothermal well to target depth and at planned trajectory, 60 days ahead of schedule. -
When humankind returns to the Moon to establish colonies it will be bringing with it technologies born in the oil and mining industries. The European Space Agency and Russia’s Roscosmos will be central to that effort as they prepare to land a robotic drilling system to extract oxygen and water from frozen lunar soil.

The authors describe challenges that must be overcome to reach the goal of drilling systems automation.
-
This paper details the introduction of a drilling automation system to deliver superior well-construction performance in a major gas field.
-
MPD was used to successfully drill through a pore pressure ramp and address a well-control event in conjunction with conventional methods.
-
Drilling automation and innovation continue as dominant trends despite market downturns and unprecedented challenges in the past year. In many ways, the drive toward new efficiencies and step changes in well-construction performance has taken on an even greater sense of urgency.
-
The cutting-edge technological developments in geothermal are devoted to drilling into deeper, hotter, and harder rock. Oil and gas expertise and know-how holds the key to cost reduction.
-
The complete paper discusses a geophone array, including four, three-component geophones deployed by wireline, that provides a solution for this problem by creating a 3D map of the acoustic environment.
-
The complete paper presents a solution that integrates a physics-based torque-and-drag (T&D) stiff/soft string model with a real-time drilling analytics system using a custom-built extract, transform, and load translator and digital-transformation applications to automate the T&D modeling work flow.
-
The complete paper discusses a new performance-evaluation methodology that combines bottomhole assembly (BHA) modeling with field data.
