Completions
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.
-
While there is increased scrutiny from regulatory and community stakeholders on the chemicals used in operations, complex and technically challenging reservoirs must be developed to replace reserves. Matrix stimulation remains a critical technology for delivering barrels at minimum cost.
-
This paper details the planning, design, and execution of a project involving the core drilling of three wellbores using coiled-tubing directional drilling along the future Rogfast tunnel route on the Norwegian coast. -
The installation of flowlines in ever-deeper and -more-remote areas requires specific technologies for precommissioning. Coiled tubing can be a solution, but long durations may affect tubing stress and fatigue.
-
Larger-diameter coiled tubing recently has been used to perform millouts because of its improved set-down force and increased annular velocities for cleanout purposes. Service companies and operators have reduced the number of wiper trips when using larger-diameter CT, to save time and money.
-
Carbon dioxide (CO2) with 30% foam quality (FQ) has been introduced for the first time during acid fracturing treatments in a tight, sour, high-pressure/high-temperature carbonate gas reservoir in Saudi Arabia.
-
This paper presents experimental and field-case studies with a sandstone-acidizing treatment designed to retard the hydrofluoric acid reaction rate and enable single-stage treatment.
-
This paper studied three residual-free fluid systems for acid treatments and fracturing in order to develop no-damage or reduced-damage and highly effective stimulation techniques for long-interval wells.
-
A 2-year comprehensive effort to design, test, manufacture, and deploy a new high-pressure completion tubular for Chevron’s deepwater Gulf of Mexico (GOM) operations is presented.
-
A study done to find the root cause of coiled tubing string failures in Montney indicated microbial-induced corrosion, leading the CT service provider to create a biocide treatment program.
-
A service using pressure data from a few nearby unconventional wells to map fracturing will soon be for sale.
