ADNOC Onshore 24" Main Oil Spurline -1 transferring stabilized crude from Buhasa field (BUH) to MP (Mile Point)-21 hub had a defective 24" Gate Valve on the upstream side of Pig Receiver at MP-21. The Objective was to replace the defective valve with a refurbished 24" Gate Valve with minimum production impact and without the need for depressurizing /draining the entire 35km section of 24" pipeline from BUH to MP-21. A novel isolation technique using Tethered TECNOPLUG was identified and utilized for successful replacement of the defective upstream valve without causing any impact on the oil production.
In 2017 the Abu Dhabi National Oil Company (ADNOC) made the decision to image the entire Emirate's subsurface (onshore and offshore) with 3D seismic. In addition to covering areas little explored before, and refreshing old images with modern technologies, the goal is to explore specifically for unconventional resources and shallow gas. Imaging both shallow and deep targets, in areas known for low signal-to-noise ratio, requires intense field efforts and elaborate processing sequences. Acquisition started in late 2018 and is scheduled to finish early 2022 with a final image delivery two years later.
Reservoir management guidelines are an enabler of, production sustainability, assurance to reservoir health and high ultimate recovery. Monitoring the compliance of the field production against the set of reservoir management guidelines is one of the key processes for ADNOC, being a governing body of major U.A.E. hydrocarbon producing fields.
With the business need to ramp up production, field maturation, and the associated operational challenges, it is critical for ADNOC to effectively monitor and regulate its field production plans to assure the long-term production sustainability. In this regard, ADNOC has developed a robust framework that is implemented through an automated analytics platform that enables different ADNOC technical teams to effectively monitor and report the compliance status of each hydrocarbon barrel from produced from ADNOC assets. The paper highlights the features of the workflow implemented, the management of change strategy and the business value created.
The automated process allows the consolidation of a variety of well, reservoir and field-level data. The analytical platform enables integrated analysis, KPI calculation and interactive visualization. The framework assesses the compliance based on three governing parameters: well technical rate, gas-oil ratio (GOR), and bottom hole flowing pressure. The compliance analysis is carried out on a monthly basis where the monthly back allocated production data for each well is compared with the set of operating guidelines in an automated data analytics and visualization environment. A pragmatic compliance tolerance is considered in the calculations to accommodate the measurement inaccuracies, as well as the operational limitations while allowing flexibility to exclude nonconformity with valid reasons.
The overall process is governed through an automated business process management (BPM) platform, which seamlessly regulates the predefined subroutines among different stakeholders to report and track different corrective actions in a timely manner.
The framework implementation has strengthened the overall compliance governance process; and has been instrumental to properly manage asset production capacity in a systematic manner. This has subsequently enabled the preparation of a prompt action plan and has improved the operating efficiency of more than 3% within the first six months of implementation, through restoring, compensating and increasing the effective capacity of overall ADNOC Production.
The approach has demonstrated great value both in terms of process alignment, as well as from the production assurance standpoint at a country level, and allows the organization to have an established system, which provides: Consistent compliance monitoring standards Minimal subjectivity Complete process governance Quick turnaround time Auditable history
Consistent compliance monitoring standards
Complete process governance
Quick turnaround time
The aim of this paper is to publish a stepwise guide for any operators who might be interested to adopt and implement a similar approach to assure the long-term production sustainability and health of their assets.
The Project portfolio in the Oil & Gas industry across the value chain is quite large. Significant investments are done in complex environments to manage these Portfolio with annual budgets in International Oil Companies and National Oil Companies running into several billions of dollars. There are many challenges managing Projects and one of the key functions that helps in managing Projects is "Project Controls".
A Unified Value Assurance Process for Projects in the Upstream Business unit was rolled out in July 2015. Based on the learnings from previous project execution and challenges to manage Project schedules, cost, budgets and risks, it was felt that the knowledge level of the Project Management and Project controls function needs to be raised. It was in this context that an idea to set up a Projects Academy came about. Preliminary evaluation for this academy showed extensive efforts, coordination, involvement of external parties and extended time to get the Project Academy set-up. As a quick win, the upstream business line supported the establishment of a "Project Control Learning Academy" with in-house resources.
We will present in this paper how the Project Control Learning Academy was set-up and training being imparted through Human Capital function. We will also address the lessons learnt and the future course of action for enhancing the Academy.

ADNOC Gas Processing, in its journey towards energy excellence, has adopted a novel in-house methodology for energy performance benchmarking. This methodology is primarily focused to unit & equipment level performance comparison, to identify gaps and highlight opportunities for improvement following the best international practices. Benchmarking is an evaluation of any aspect by comparing it with a standard or any other reference at different levels and scales. Generally, in an Oil & Gas Industry, auxiliary boilers mainly consume natural gas to produce steam for process heating. Energy performance of boilers is susceptible to decline due to several reasons and results in reduced efficiency. Owing to the significance of auxiliary boilers energy performance in the overall energy efficiency of gas processing, ADNOC Gas Processing conducted an in-house energy performance benchmarking of auxiliary boilers installed at its multiple sites.
Energy performance of total twenty five (25) auxiliary boilers was analyzed and evaluated in terms of different indices, to examine their current performance and benchmark it with other boilers for potential improvements. Benchmarking also assessed overall steam and condensate systems. Opportunities for improvement were observed in areas of process optimization, best practices and CAPEX based energy efficiency initiatives. Benchmarking exercise revealed energy savings opportunities in flue gases excess oxygen optimization, make-up water management, energy recovery from pressure letdown stations, waste heat recovery and steam traps audits. Study also highlighted areas of improvement in performance monitoring encompassing metering, sustained optimization and continual improvement.

Downhole Safety Valve is an integral part of Well Integrity Mangement System and acts as a failsafe equipment to prevent uncontrolled release of reservoir fluids. Periodic inspection and maintenance of downhole Safety Valve is essential under normal service conditions. Each Downhole Safety Valve should be tested and lubricated at specified regular intervals as recommended by ADNOCs Standard Operating Procedure and as dictated by field experience. Since it is a Critical Safety Equipment, preventive maintenance of Wireline Retrievable type downhole Safety Valve is being carried out annually which involves valve retrieval, leak/function test and redressing if required. Current practice within ADNOC Onshore is to carry out redressing with third party for all Wireline Retrievable Safety Valve annually or in case they are observed to be passing (not meeting the maximum acceptable gas leak rate of 15 scf/min for gas and 400 cc/min for liquid) or do not pass function test carried out during 6 monthly and yearly Preventive Maintenance Schedule. The cost incurred for third party redressing is substantial and can be optimized by evaluating the possibility of carrying out redressing in-house with available resources and using Original Equipment Manufacturer redress kit in situations where internal leak is not observed in the valve and valve can be redressed without the need to open tension spring and flow tube which requires extensive redressing setup available with third party. The new proposal helped in saving cost and time for redressing by utilizing the available resources and formalising in-house redressing wherever applicable under compliance to ADNOC Onshore competent authority guidelines.
