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.
This study aims to systematically assess casing integrity and corrosion risks associated with CO2 injection in oil-recovery operations.
This paper presents findings reinforcing the argument that acid fracturing is a strong alternative stimulation method to improve productivity in the Austin Chalk formation.
-
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.
-
Low oil prices look like something the industry needs to get used to. “This will be with us for a while,” said Rex Tillerson
-
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.
-
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.
-
In this cost-cutting market environment, completion engineers face added pressure to maximize the return on every dollar invested when putting unconventional wells into production.
