Increased production alongside low costs has always been a long-standing goal for operators in a time where the industry is thriving to increase their operational and economical efficiencies. For maturing fields, operators are constantly seeking innovative techniques to access large quantities of reserves found in low permeability formations.
The nature of the reservoir has resulted in an economical need to implement a hydraulic fracturing campaign. This would assist with increased production through wider contact area of the producing interval. After a campaign resulting in favorable results through hydraulic fracturing, additional efficiencies addressing the operational and cost concerns of cemented plug & perf were required. In order to maintain production increases while maintaining operational efficiency, the need for multi-stage hydraulic fracturing became evident.
Six candidate wells were selected for proppant fracturing utilizing a multi-stage completion technique that has been widely adopted in North America for the past 17 years and internationally for over a decade. The technique utilizes a series of hydraulic mechanical packers and fracturing ports that are shifted open sequentially across the applicable zones targeted for treatment. The ports have seats that are sized to respective balls, which are used to isolate the stimulated intervals. The system allows for increased efficiency through eliminating the risks associated with wireline operations for perforating, or coiled tubing operations to mill out bridge plugs. It also allows for immediate and simultaneous production from all stages as well as contingencies for shutting off water zones. From June 2016 to March 2017, six systems were installed consisting of 6 to 8 hydraulic fracturing stages, which were placed in cased-hole pre-perforated wells.
This paper investigates reservoir quality assessment as well as the stimulation efficiency and productivity enhancement of the Sidri Field. It investigates two different completion methodologies to investigate operational efficiency and productivity enhancement of the Sidri Field in the Sinai Peninsula. The comprehensive evaluation will involve discussions of candidate selection, pre-job design alongside comparisons of timeline, cost, zonal isolation, and productivity to help serve as a guideline for operators in the region looking to enhance their completion approach.

DSATS (SPE’s Drilling Systems Automation Technical Section) will hold a half-day symposium featuring keynote presentations on urban automation. This symposium will explore technologies being used in developing smart cities through the automation of their infrastructure, transportation systems, energy distribution, water systems, street lighting, refuse collection, etc. These efforts rely on many of the same tools needed for drilling systems automation yielding increased efficiencies, lower maintenance and reduced emissions. Their knowledge and experience can guide the path being travelled by the oilfield drilling industry.
Exploration in 2018 got off to a strong start when the Chevron-operated Ballymore well encountered 205 m of net oil pay in the US Gulf of Mexico. Drilled by Pacific Drilling’s Sharav deepwater drillship, the well reached a total depth of 8,898 m. Global discovered oil and gas resources and big project sanctions are expected to remain on the upswing through next year, according to separate industry outlooks from Rystad Energy and Wood Mackenzie. Internalizing lessons from a difficult last few years, operators are choosing investments more wisely and now better prepared to deal with volatile oil markets, the consultancies concluded. "Portfolios are set to weather low prices, and the recent slide in prices justifies the sector’s conservative mindset."
Crucial milestones are reached during these relatively short periods which are however characterized by high risks and high expenses. Thorough preparation and intense cooperation among various disciplines are therefore required to make them a success. This session shall focus on how to improve future operations in the East-Med by reducing risks with adequate planning, coordination, or technologies, or by increasing efficiency through synergies, simplification, and standardization. Presentations and papers should highlight such solutions, either building on specificities of the East-Med context and recent local experiences, or highlighting other experiences that might be applicable in the East-Med. A wide variety of topics can be covered, including but not limited to the optimization of data acquisition or logistics, the management of geological uncertainties (salt stability, pressure regime, etc.) while drilling, and the installation of infrastructure (pipeline, subsea equipment, etc.).
We'll explore topics such as the geology of Zohr-like carbonate plays, drilling issues, reservoir engineering, pipeline projects, technological advances, HSE matters, and potential synergies.

As a result of intense pressure to reduce costs in offshore oil and gas operations, there has been a surge in support and use of ruggedized unmanned surface vehicles (USVs or ASVs) for several standard tasks in Exploration and Production (E&P), Inspection, Maintenance and Repair (IMR), and Survey operations. As illustrated in several recent case studies from marine construction, seismic, pipelay, hydrographic, and environmental applications, this technology is no longer in development mode, but has in fact become a key element in the re-tooling of the offshore industry for more efficient and safer operations.
This paper addresses and reviews a number of important design considerations for ASVs being used in the offshore oil and gas industry. Applications which will be elaborated will include pipeline route surveys, ROV tracking/touch down monitoring, LBL array box-in and calibrations, as-built geophysical surveys for pipelines, unmanned seismic energy source operations for reservoir monitoring, marine mammal acoustic and visual monitoring, and hydrocarbon leak/seep detection operations.
Included in this paper are case study observations and data from projects offshore Europe, Gulf of Mexico, the Mediterranean Sea, and Alaska. These results in several cases will also be presented to provide a clear comparison between standard methods showing the cost savings achieved by use of this technology. In all cases, the decreased project costs were made in parallel with no loss of data quality. In some cases, an improvement in data quality over standard methods was made, along with the decreased operational costs.
The use of unmanned surface systems in offshore oil and gas operations has become a proven cost reduction tool. A growing number of contractors and operators are now using this technology with good results. In some cases, operators are now specifying this technology be offered by their contractors in order to reduce costs, with measurable results. The decrease in at-sea man hours has also provided a significant risk reduction aspect.

Objectives/Scope: The retrofit of cathodic protection systems of offshore platform is crucial for the extension of existing oil and gas fields life in the present economic scenario of oil low pricing. Tensioned string anodes is a reliable way to afford this problem in a fast and efficient way with CAPEX savings. Methods, Procedures, Process: A real case of retrofit of 4 platforms in offshore West Africa is presented with focus on technical and economical aspects. The technical review will cover the analysis of anodes and cables residual life after 18 years in operation in seawater as well as design and installation procedures. The economical analysis is aimed to compare the costs for galvanic vs. impressed current cathodic protection for the retrofit of oil rigs CP systems in shallow and deep water in order to allow easier ROI analysis.
AbstractRectangular mudmat foundations for subsea structures are commonly designed according to ISO and API guidelines. However, the modern trend towards deeper waters and heavier structures is currently challenging traditional approaches to foundation design, especially in presence of particularly poor soil conditions. The intrinsic conservatism carried by design codes may not only lead to higher fabrication/installation costs, but also conflict with the operational limits of existing installation vessels.Based on the analysis of four design cases, it is argued that ISO/API safety factors may be from 1.5 to 2.3 times as low as the predictions of elastoplastic finite element (FE) simulations. Such a conservatism is also found to considerably increase with the embedment depth, whereas the influence of the foundation aspect ratio is nearly negligible. A simple calculation example shows that the systematic use of numerical analysis in design may result in a 47% reduction of the total foundation area, and an overall decrease in fabrication costs of approximately 16%.
Clean Sea is an underwater robot developed by Eni and Tecnomare (since January 1st, 2017 renamed EniProgetti) for Environmental Monitoring and Asset Integrity in oil & gas offshore installations. It is composed of a commercial hybrid ROV/AUV and a set of interchangeable payloads that feature a common power & data interface for data logging and intelligent autonomous mission online reprogramming, according to payload measurements or other external events.
Clean Sea technology had been validated in extensive trials carried out in simulated and real oil & gas scenarios in 2014 and 2015: Lake Vattern (Sweden), Barents Sea, Caspian Sea, Mediterranean Sea. In 2015, Clean Sea system had completed the transition from research to operational applications with two pipeline network surveys in the Mediterranean Sea.
Results obtained show high value of the technology developed by R&D, especially in terms of improved environmental monitoring and protection, high versatility thanks to the payload modularity, low logistics requirements with significant cost savings. Future offshore campaign are encouraged by the great number of available functionalities and new functionalities that may be combined to get the best possible result according to business needs.
Considering two Clean Sea systems deployed in 2016, Eni is now in a position to better monitor its offshore installation and surrounding marine environment. The Mediterranean Sea and West Africa, where Eni directly operates its offshore installations, are the first locations where Eni has started using Clean Sea.
A dedicated team has been set-up, trained and based in EniMed, Eni’s subsidiary operating in Mediterranean area, who will manage Operating & Maintenance activities of the Clean Sea system. The Clean Sea team will be in charge of all offshore campaigns to guarantee a full exploitation of this Eni-patented new technology.
