This paper presents a study that confirms glass-reinforced-epoxy-lined tubing as a reliable, cost-effective solution for long-term water-injection service in moderate-salinity offshore environments.
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.
-
Over the next few years, water treatment technologies are expected to continue to be deployed in the basin, as drought drives aquifer levels to new lows. -
I think it is safe to say that the engineers and companies involved, in either building or using sand-control systems, have made significant strides and have added critical learnings to our industry.
-
Although multiple-zone, downhole sand-control-tool systems have been in use since the early 1990s, these systems have been designed for jobs that require only low pump rates with low pressure differentials.
-
Standalone-sand-screen (SAS) completion, especially in horizontal gas wells with high potential for sand production, typically suffers from premature failure caused by sand erosion resulting from high velocity in the annulus near the heel section.
-
Large amounts of clay minerals are present in shale; shale’s resulting instability is a major problem while drilling.
-
Upstream separation processes remain a hot topic for facilities engineers. Striving to design separators with the optimal sizing for a variety of reservoir conditions, increasing water cuts, and dynamic gas/oil/water production characteristics is critical, but challenging.
-
While storage and logistics are critical elements of the viability of water reuse, if the water chemistry is not fit for gel fracturing formulations, it will not matter how much is stored in centrally located impoundments.
-
Evenly fracturing all clusters in heterogeneous zones is challenging in long horizontal sections penetrating heterogeneous reservoirs, as is often the case in the Eagle Ford shale.
-
The gas-producing carbonate zones of the Ghawar field in eastern Saudi Arabia have been affected by extensive iron sulfide (FeS) scale deposition, reducing overall gas production and increasing risks during well interventions.
-
An innovative approach resulted in the development of an ultra-HP/HT permanent bridge plug for long-term exposure at 25,000‑psi pressure and temperatures of 500°F.
