This paper introduces in-pipe inspection technologies enabling high-resolution digital measurements of tubular internal diameter and wall thickness for critical downhole applications.
Output is rising fast in the South American shale play and putting Argentina on a course to soon reach 1 million B/D.
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.
-
Microbial-influenced corrosion (MIC) has been implicated in few corrosion-related challenges in the well-service industry in the past. -
A common problem in oil and gas wells is excess free gas or water production from only certain portions of the completed interval.
-
The technical contributions highlighted this year focus on matrix stimulation of carbonate and unconventional reservoirs.
-
Core-flow tests are usually conducted to test and model stimulation treatments at laboratory scale, to predict the performance of such treatments in carbonate reservoirs.
-
Mechanical-diversion techniques can ensure acid injection into the various intervals of naturally fractured reservoirs.
-
An operator developing tight carbonate reservoirs found that conventional acid stimulation with 15% hydrochloric acid (HCl) in horizontal wells did not provide expected results.
-
When it comes to fracturing, experts argue about many things, but they agree that fractures do not look like lightning bolts, tree roots, or shattered glass.
-
Al Khalij field offshore Qatar is formed of a highly heterogeneous carbonate reservoir with significant remaining dynamic uncertainties.
-
As shale operators look for ways to survive amid the current downturn in oil prices, accelerating the refracturing of older horizontal wells is turning into one of the most attractive options.
-
At the SPE Hydraulic Fracturing Technology Conference, one of the most innovative ideas discussed was a liquid proppant designed to turn into strong spherical balls to keep a fracture open.
