Casing/cementing/zonal isolation
A multidimensional Wiener process approach predicts casing remaining useful life, enabling safe, cost-effective well life extension and repurposing for carbon dioxide injection, CCS, and geothermal applications.
The paper describes a multientry multistage fracturing technology developed to enable longer laterals, increase stage counts, improve stimulation efficiencies, and derisk operations.
This study identifies critical knowledge gaps in wellbore integrity and underscores areas that require further investigation, providing insights into how wellbores must evolve to meet the technical demands of the energy transition.

A major operator manages multiple deepwater projects in the Gulf of Guinea. This paper describes one of these, a recent 44-well project. -
Well RXY is located in Cairn’s Ravva offshore field in the Krishna-Godavari Basin in India. One goal for the field was significant crude production by means of a secondary reservoir section.

This paper compares the results of gas identification and lithology identification using pulsed-neutron spectroscopy in openhole and casedhole environments.
-
Acquiring data from an abandoned subsea well has been done before, but never quite like this.
-
The $10 million/year contract covers the inspection and mobilization of casing and tubing at two Norwegian sites and includes extenstion options in 2020 and 2022.
-
This paper reviews the technology trends in cement-job evaluation using logging tools and considers the main advantages and concerns associated with each technology.
-
As I read through the abstracts and papers that have been presented in the past year, I notice several key themes: verification of cement placement, development of new materials as a barrier, development of new additives to improve the cement barrier, and enhancement of existing techniques.
-
This paper reviews a successful managed-pressure-cementing (MPC) operation and presents findings and lessons learned.
-
Operators at a UAE field experienced several challenges while cementing production sections. A systematic approach was applied that used standard cementing best practices as a starting point.
-
This paper presents a concept that enables simultaneous drilling and completion, with an aim to extend well reach substantially and with an ultimate objective of constructing 30-km-long production wells.
