Drilling
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 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.

To maintain zonal isolation throughout the life of a high-pressure/high-temperature (HP/HT) well, the cement sheath must perform reliably at temperatures that can exceed 315°C. -
The Granite Wash formation presents several challenges in drilling the build section from a vertical open hole to form a lateral.
-
As operators continue to drill into deeper and more-extreme formations, the demand for technologies suited to these environments increases.
-
With exploration in harsh environments and consequent high-pressure and high-temperature conditions, calculating reservoir properties has become complex and changes in pressure-transient response need to be understood and appreciated by taking appropriate measures.
-
FPWD provided a direct pressure measurement while drilling to set the lower boundary, and formation-integrity tests (FITs) with MPD provided the upper boundary.
-
We all know that things have changed significantly for offshore drilling and completion in the last 3 years. Regulations have been reviewed, and operational procedures and requirements have changed.
-
A brief primer on managed pressure drilling (MPD) and how it compares with underbalanced drilling (UBD).
