Fracturing/pressure pumping
This case study presents a procedure in which the operator compared production from wells with adjusted wettability to a control group, finding that the adjustments resulted in significant improvements in production and reductions in produced water.
Output is rising fast in the South American shale play and putting Argentina on a course to soon reach 1 million B/D.
This paper presents findings reinforcing the argument that acid fracturing is a strong alternative stimulation method to improve productivity in the Austin Chalk formation.

Pumping fracturing jobs is an equipment killer. The job requires running enormous quantities of water and sand through a pump, which is an abrasive mix that damages pumps in ways that cannot be fixed. Adding to the pressure is the trend toward clustering wells on pad sites that extend run time. -
Hydraulic fracturing solutions use a gelling agent known as guar gum to transport proppant. Flowback water can have guar gum concentrations has high as 1% by volume creating treatment challenges prior to reuse or disposal.

For those in shale exploration, “fracability” is a real word, a critical property, and a point of contention.
-
With inconsistent inlet water quality being the rule rather than the exception, sizing and operational considerations of the treatment system components must vary accordingly to make the most economic sense.
-
While shale unproved technically recoverable resources have been identified around the world, development has been limited to North America.
-
Some operators are returning to their North American mature unconventional shale wells to refracture, or restimulate, the rock to accelerate production and enhance ultimate recoveries.

At the 2014 SPE Hydraulic Fracturing Technology Conference in February, former Texas A&M Department of Petroleum Engineering head Stephen A. Holditch received a well-deserved lifetime achievement recognition, the Legends of Hydraulic Fracturing Award.

The purpose of this paper is to apply multivariate statistical modeling in conjunction with geographic-information-systems (GIS) pattern-recognition work to the Eagle Ford.
-
Production from the Bakken and Three Forks formations within the Williston basin is continuing to climb as a result of applied horizontal drilling and hydraulic fracturing.
-
Using large-scale hydraulic-fracturing experiments on tight shale outcrops, three dominant regions controlling stage production were identified.
