Microbes—Oilfield Enemies or Allies?

Microbial organisms have a long history of coexistence with oilfield operations. Microbes often cause corrosion and reservoir damage, but sometimes they enhance production. Scientists are using new knowledge of microbe identity and chemistry to combat microbial damage and to encourage microbiologically enhanced oil recovery.

Drilling Automation

Drilling automation involves much more than rig floor mechanization; with the integration of downhole data with operations, improved drilling performance can mean the difference between economic success and failure. At the same time, in the large numbers of wells whose conditions are understood.

Seismic Detection of Subtle Faults

Natural fractures complicate the development and production of hydrocarbon reservoirs. Because they are typically smaller than seismic wavelengths, fractures are difficult to detect and characterize. Advances in seismic processing and visualization are helping operators place wells inside fractured formations and manage fractured reservoirs better.

Logging Through the Bit

High-angle or extended-reach well trajectories sometimes cause operators to forgo openhole logging. However, without petrophysical data, operators have scant information for making important decisions that could affect the producibility of their wells. The operators deployed small-diameter logging tools through specially developed drill bits.
