... requirement of that field. The ability to maintain well integrity during construction and provide full access to the well throughout the its life cycle can be difficult. Lateral access is necessary for production optimization, reservoir management, and well treatment to enhance production and even to revive...

... at the blender would be delivered to downhole with integrity. These success of these efforts is proven by the outstanding post-fracturing results of two vertical wells and one horizontal well in 2021. Despite the discrepancy in reservoir quality, all the wells had faster cleanup period, less gas kickoff, and 80...

... a hydrocarbon gradient. In both scenarios, the external pressure profile assumes the original hydrostatic column of mud used to land the casing as a worst-case scenario for collapse. The consequence of a loss of liner hanger system integrity for an unforeseen reason was also assessed. In wells where...

... surfaces facing the formation) to reinforce its resistance against severe erosive environment. An extensive development and verification program was conducted to select over 50 possible coating combinations, guarantee predefined slot size, assess corrosion resistance, and ascertain mechanical integrity...

... Over the years, various methodologies have been used to analyze cement integrity. They can be mainly grouped under three categories based on the tool used. The first method uses scaled-down samples and X-ray computed tomography for microstructural characterization ( Opedal et al. 2014 ; De...

... to bring fully integrated projects to the sector that can store more than 50 million tonnes of CO 2 over a 30 year period. The program, enacted prior to the enhancement of Internal Revenue Code Section 45Q, is in the capture assessment, characterization, and permitting phase. The objectives of this paper...

... Effectively evaluate WI risks for thousands of wells. Concentrate on the share of each integrity element in the whole envelope and as a result, the model become strong tool for risk evaluation and WI categorization. Successfully guide senior management for efficient dedication of existing...

...Chemical Inhibition : Abstract Objective/Scope Integrity of the wells and facilities is planned right from the reservoir development phase. In the pilot phase all the contributing parameters are collected and considered in the design of the production facilities. As the corrosion/erosion...

...INTRODUCTION ABSTRACT During perforating operations, identifying the orientation of fiber cable accurately is critical for maintaining the integrity of permanently installed fiber.Beyond completions,it alsoprovides insights into how the casings get twisted and how the mechanical stability...

... yard test was designed, and field case studies were used to integrate all the branches. Field cases showed a diversion pressure up to 4,000 psi depending on perforation strategy, pill volume, and pill seating rate. Correlations showed the interdependence of multiple parameters in diversion processes...

... into the reservoir and may reach the reservoir caprock, which may decrease the integrity and possibly lead to out of zone injection. The study of evaluation of downhole fracture monitoring is divided into two parts. In the first part of the paper ( Kohli, et al., 2021 ), a downhole verification approach to identify...

... laboratory testing, an integrated engineering approach to fracture modeling, operational considerations, and post-fracturing production analysis. The workflow evolved during the technology implementation cycle in a specific oil field, particularly the modeling step, which used a new high precision...

.... To extend the life of the well and to add reserves from the secondary target, the upper 100% water zone had to be isolated. A fit-for-purpose, thin wall casing patch solution was designed to: allow perforation of the secondary target while maintaining patch integrity, allowing for the installation of sand...

... tested until the tubes lost the pressure integrity. Maximum pressure test value and observation from the loss in pressure integrity is given in Table 2 . All the sample exceeded design basis burst pressure limit of 10,000 psi. Sample 6 lost pressure integrity at slightly above 10,000 psi because...

... or microannuli occur and hydrocarbons reach the cement, the system has the capability to repair itself, restoring integrity of the cement sheath without external intervention. The cement system is placed conventionally in the annulus across or above the hydrocarbon-bearing formation. It then acts as a pressure...

... Abstract Offshore field started on operation to produce crude oil with 27 API° as sweet crude and sour crude with 32 API° since 1960. Large number of wells in offshore field revealed undesirable phenomena related to well integrity issues as potentially sustained pressure on several casing...

...Introduction Being able to systematically identify and manage the most critical wellbore integrity risks based on structured, transparent measures is a significant challenge, in particular in the thermal oil recovery sector. One of the dominant reasons is the demanding conditions...
