Drilling/completion fluids
This paper presents the application of degradable particulate-diverter technology to improve oil production by effectively diverting stimulation treatment fluids away from high-water-cut, high-permeability, high-temperature producing intervals or zones.
Adequate consideration must be given to the potential effect of each fluid on the successive phase operations to ensure integrated well-fluids system management.
This paper presents the methodology for developing drill-in organophilic clay-free invert-emulsion-fluid technology that enhances well production through fundamental geological studies and fluid testing.

For nanotechnology-based drilling fluids, acceptance means proving they can outperform other drilling fluids. Initial results have been encouraging enough to move toward commercialization. -
With shrinking budgets and limited resources, partnerships and collaboration are considered the best options. It is no secret that universities and industry have a special platform to work hand-in-hand.

The wireline formation tester (WFT) is a well-developed technology used to collect representative downhole fluid samples. The authors introduce a simple but effective method for monitoring WFT sampling when targeting the low levels of contamination needed for asphaltene-onset-pressure analysis.

This work focuses on the laboratory techniques for developing, assessing, and analyzing innovative water-based drilling fluids containing iron oxide (Fe2O3) and silica (SiO2) nanoparticles.

At certain conditions, the good performance of synthetic-based mud (SBM) will degrade, particularly because of the effect of chemical instability under high temperature. Silicon dioxide (SiO2) nanopowder (nanosilica) holds the potential for performance improvement.

A long-time energy industry executive and chemical engineer has built a new water treatment system that he says can increase recovery rates from shale wells without using chemicals and will recycle all the water used in the process.
-
A challenge in many permeable, water-sensitive, subhydrostatic reservoirs is avoiding the loss of completion fluid when completing or working over wells.
-
The inventor of a new water-based drilling fluid believes the chemical process involved with his technology opens up natural fractures as drilling takes place to increase production in shale formations.
-
This paper presents experimental research in which a significant fracture-pressure increase was achieved in shale and the predominant wellbore strenghtening mechanism was identified.

The strength and conductivity of proppant packs are key parameters for assessing their performance. This paper introduces a new analysis technique based on interpretation of acoustic measurements to quantify mechanical damage in propping agents.
