Drilling
This paper aims to establish a set of best practices for generating particle-size-distribution data from core samples.
This paper discusses the successful execution of two openhole gravel-pack completions in two Gulf of Mexico fields with depleted reservoirs.
This edition highlights three offshore technology papers that address a common industry theme: how targeted engineering solutions can reduce uncertainty, shorten operations, and make technically constrained offshore well activities more executable.
-
In 2012, the number of unconventional tight gas/shale and high-pressure/high-temperature (HP/HT) papers continued to grow. This year, we had some very interesting developments in these and other areas of well construction. -
This case history presents the highly challenging extended-reach deepwater well, Ursa A-10, drilled in the Ursa (Latin for bear) prospect in the US Gulf of Mexico (GOM).
-
The Eagle Ford shale in Zavala County, Texas, is similar to many high-carbonate-content oil-shale formations.
-
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).
