Performing well intervention for production logging and data gathering in extended reach, complex trajectory wells, poses significant challenges to conventional technologies traditionally used. Well profiles with a measured to true vertical depth ratio exceeding 4.5:1 (MD/TVD) and horizontal intervals beyond 20,000 ft., demand the latest technology. High-resolution down-hole sensors, advanced robotic conveyance tools, and specialized deployment systems provide real-time fast and reliable data transmission to optimize each well intervention. Accurate well performance evaluation is essential to long-term reservoir management in MRC type wells, where early detection of production uniformity provides vital data required to maximize recovery. Conformance diagnostics and remediation rely entirely on well intervention technologies for low-cost well remediation. This session will discuss advances in both wireline and coiled tubing conveyed technologies engineered explicitly for extended-reach applications, providing relevant case histories that focus on the challenges and solutions developed to achieve operational objectives.
Drilling and well construction are considered some of the most critical phases in the life cycle of an offshore oil and gas well. However, in a demand-driven energy economy that is ever growing, operators, drilling contractors, and technology service providers are faced with the challenge of not only delivering high quality wells on time, but having to do so in the most economical and efficient way possible, without compromising operation safety, well integrity, or production quality. This session will explore the role of applying the right technology in pushing the offshore drilling efficiency boundaries further, to deliver the optimum well design while addressing challenges such as drilling and completing wells while managing abnormal pressure zones, loss circulation, hole instability, depletion, well control, and sour gas operations. The depth of the target reservoirs and the environmental constraint often affect the design of the wells offshore, hence, having the latest technologies could be an enabler for drilling teams to push the boundaries of efficiency further while addressing the challenges of drilling and completing deep and extended reach wells. This session will also attempt to discuss the concept of breaking performance barriers, and attempt to explore the idea of where are the limits?
This paper describes preparations and planning for a campaign of foam gas shut-off pilot operations in a large carbonate reservoir located offshore Abu Dhabi containing an oil column in equilibrium with a large gas cap. Throughout the field history and due to the heterogeneity (permeability ranges from 5 mD to 1 D), the major challenge to produce the oil rim independently from the gas cap was how to control premature gas breakthrough in the oil producers. Mechanical interventions in high gas-oil ratio wells are particularly complicated due to the risk of losing oil potential and are generally unsuccessful.
Injection of foam for gas shut-off (FGSO) is a near-wellbore treatment, which has been trialed elsewhere in the industry with some success. Foam can act as an auto-selective agent to shut-off confined gas inflow through a gravity-controlled source like coning or cusping, while oil breaks the foam, resulting in preferential oil flow and reduction in gas-oil ratio. In addition, this type of operation has been identified as an EOR enabler, because it can help prepare for the technical and logistical challenges of using EOR chemicals in the field, generate data useful for the modeling of surfactant and polymer under reservoir conditions, and mitigate early gas breakthrough in the case of gas-based EOR developments.
For the reservoir in question, a key complicating factor was to identify a surfactant, which could generate strong foam in-situ (mobility reduction factor of 50) at harsh reservoir conditions (temperature of 220-230 °F and water salinity above 200,000 ppm, including 20,000 ppm divalents), with an acceptable level of adsorption. The candidate selection process took into consideration overall behavior of the reservoir as well as performance of the individual high-GOR wells. Target well selection criteria included homogeneity of permeability, an understanding of gas sources and their movement, and observation of a rate- or draw-down-dependent GOR.
The experimental lab program involved testing several surfactant formulations in bulk as well as in corefloods with and without the presence of reservoir oil to evaluate foaming ability and level of gas flow reduction. One formulation showed the right level of in-situ mobility reduction, in addition to stability and moderate adsorption at the prevailing reservoir conditions, and was therefore selected for a pilot test involving four wells.

Through this paper, the author intends to share the valuable experience and benefits of introducing the key element of Integrity Assurance - the initial inspection during the EPC warrantee period in a structured manner and ensure the risks are minimized into the commissioning and Operating stages for major critical project.
ADNOC OFFSHORE is recognized for its pioneering and innovative approach. As one of the major Oil & Gas producers worldwide, the Company philosophy is to build a culture where critical Integrity Deliverables are embedded through customsied locally designed Code of Practice, known as "Integrity Assurance in Projects" that is monitored through a Value Assurance Process (VAP) stages. This enables robust control of Integrity Measures upfront and early identification of Integrity risks, with proactive mitigations based on experience from previous Projects. To further ensure the Integrity deliverables are strictly followed during the EPC; a well laid-out plan is rolled to the Project commissioning team by identifying and defining the non-intrusive NDT of piping system hot-spots as well as thorough internal inspection of typical medium risk high pressure equipment within the first 12 months of operations which fall under the EPC warrantee period. Being in the Project EPC phase, none of the items are classified under "High Risk" and are already eliminated through robust engineering. The inspection is scheduled considering minimal production impact.
Following this initiative enables a structure that is directed towards the prevention of operating critical facilities and minimizes the liklihood of unknown HSE and business risks impacting the delivery of the project to the production phase. The equipment warrentee will be in force after the successful commissioning as per EPC contract agreement.
One of the key Integrity deliverables is the implementation of Baseline Inspection. The baseline RBI Passport system has been broadly adopted across the Company operational sites and supports the safe continuous employment of assets to meet production targets. The high-risk items are already eliminated and mitigated during the EPC Engineering phase. Through baseline RBI study, the medium risk hotspots are identified for random cross-check during the EPC warrantee period with the obvious intention of ensuring the risk levels are well mitigated. If any deterioration or anomalies detected during the first inspection the same can be rectified through EPC warrantee; thereby saving the Company resources and cost. This innovative approach has been successfully implemented in all of the current on-going Full Field Development projects and has proven to be of great value by ensuring a high quality result whilst attracting significant cost savings. Some of the key successes realized through the roll out of the warrantee period inspection initiative include: Early interventions through selective assessment particularly the medium risk hot-spots. This is achieved by using NDT contract team and cross-checking of the actual site inspection atleast 6 months after commissioning to ascertain the process conditions and impact on the newly commissioned facility. The project realized advantages such as the timely realization of risk reduction. Early identification of these risks led to a significant cost saving in CAPEX / OPEX and enabled a smooth handover at the commissioning stage. Long term benefits have proven to aid the identification and prevention of failures, minimize the occurences of unplanned shutdowns, and optimization of the Preventive Maintenance & Inspection program. Any surprises related to non-compliances are addressed through the valid EPC contract. Realisation of these benefits and repetitive cost savings provides added confidence to stake-holders during the entire life-cycle of the facilities.

ADNOC OFFSHORE is the first and only company within the ADNOC group to roll out such an initiative and encourage proactive direct involvement and integration of the Asset Integrity Division functions for a major full field development project. It is believed that this is also a unique approach for the MENA region by injection of decades of operational skill, knowledge and experience together with and lessons learned into the early project phases.
Executive Plenary Session: What Does Efficiency Mean? Swings in the oil and gas market have a substantial impact on the drilling industry, and during the last couple of years, they have taken a larger toll than before. Despite this, the industry continues to find ways to acclimate its practices and technologies to enable it to sustain long downswings. One of the areas of improvement that this industry has seen and continues to build on, is embedding better efficiencies in its approaches, practices, and technologies.
