This paper introduces in-pipe inspection technologies enabling high-resolution digital measurements of tubular internal diameter and wall thickness for critical downhole applications.
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.
-
Hydraulically fracturing and stimulating multiple horizontal wells in sequence has been rapidly adopted by operators because of the potential for production without introducing unwanted risks. -
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.
-
This paper attempts to describe some of the common problems and to help prevent some common errors often observed in diagnostic fracture injection tests (DFITs) execution and analysis.
-
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.
-
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.
