Abstract Digital well construction tools are becoming more widely considered today for well design planning, enabling automated engineering and simultaneous team collaboration under a single solution. This paper shows the results of using a digital well construction planning solution during a project’s conceptual planning stage. This method shortens the time needed to estimate the well times and risk profile for a drilling campaign by applying smart engines to quickly and accurately perform critical offset analysis for defined well types that is required for project sanction. With this solution, the Offset Well Analysis (OWA) process is done automatically based on the location of the planned well, trajectory and well architecture. Various information and reports (both subsurface and surface data) from neighboring wells is stored in cloud solutions, enabling ease of access and data reliability for both large or smaller scale data storage. The software selects the most relevant offset wells, displays the risk analysis and generates the stick chart. For a conceptual design, the risk levels can be manually set higher due to potential unknowns in surface and subsurface risks which can later be refined. Quick validation of the well design allows the engineer to design a conceptual drilling campaign quickly and more efficiently. The solution minimizes the time to perform probabilistic time and risk estimations. It reduces the risk of biased decision making due to manual input and design. This allows for better-informed decisions on project feasibility, alignment of stakeholders, increased design reliability as well as reducing the amount of time and resources invested in OWA. The work presented here is aimed at sharing the experience of applying a digital well construction planning solution specifically on the conceptual project stage and discuss the value it adds to the well design process.

Abstract Operators, service providers, and contractors are improving the well construction system using transformative digital technologies across multiple companies and within levels of disparate organizations. Well plans are managed in a new way with the creation,execution and continuous improvement of processes to materially deliver value from the onset. A typical operator’s well planning process involves developing a well program across multiple internal and external entities in the design and plan stages while various requirements and details are considered and confirmed. As the well gets closer to being drilled, the well plan must also consider the capabilities and technologies supported by the service companies and drilling contractor.This people-based process leads to variability in assumptions and objectives in standardized plans which can result in execution risk and variations in safety, quality, delivery, and cost (SQDC) performance. One major variability source occurs because of the disconnected nature in which people move data between one another in well planning documents and then to field operations. The authors propose a new way to manage this process across organization and discipline boundaries to reduce this variability. This paper details how digital technologies were incorporated into an agile pilot program to create a common framework for the exchange and management of the well plan. It follows the plan from its development to implementation in a unified, seamless process. Further the authors will demonstrate how the solution was developed across multiple organizations to deliver material value to all parties. Three companies created a collaborative business model to deliver a new digital system enhancing well construction planning and execution in terms of speed and completeness of data transfer, ease of access,and availability for building new data-based workflows and reporting. This business model continues to drive alignment throughout the companies’ well delivery business functions. This paper illustrates, "What is the value that digital transformation brings to my organization or job function".The simple answer is that if executed effectively, the transformation should produce a material improvement or outcome for the business. Digital technology creates material business value as a project management tool directly coupled with wellsite technologies. This approach, in turn, will enable improvement of the well design and SQDC performance in the delivery of the well plan.

Sea Area

Statoil has since 1985 installed, commissioned and operated approximately 8000 km of pipelines in the North Sea area. Among these pipelines are several of the world’s largest offshore gas trunk lines with the onshore parts relatively short in length but often with complex landfalls, fjord and land crossings. Since 2002 Gassco has been the Operator for transporting Norwegian gas to continental Europe and the UK. Gassco is a fully state owned company. Statoil is now TSP (Technical Service Provider) for most of the trunk lines. Operating these pipelines represents several challenges, and the accumulated experience gained through successful operations of these pipelines has brought Statoil to the forefront within the pipeline industry. Through comprehensive research and development Statoil has improved pipeline technology within areas as inspection, maintenance and repair. Together with the development of risk based condition (integrity) assessment, inspection and monitoring planning tools and work processes, these technology achievements have significantly improved Statoil’s knowledge and understanding of the pipeline condition and associated risk levels. A significant reduction in operating cost has also been experienced. Together with its collaborating partners Statoil has among others improved internal inspection technology by improving the MFL technology to a level of extra high resolution (XHR-technology) making metal loss measurements more reliable and accurate. Multi diameter inspection tools (28”–42”) (MDPT) and optical laser tool (Optopig) have also been developed and put into operation. Sub sea pipeline survey by use of ROV has been significantly improved with regard to instrumentation and survey speed. A unique remote pipeline repair contingency system (PRS) with well defined response times (10–21 days), has also been developed. To get the full benefit of these developments a risk based pipeline condition (integrity) management system (PCMS/PIMS) has been developed with the development of DnV’s Orbit Pipeline as a key element. ORBIT Pipeline consists principally of data storage and administration and various risk based integrity assessment modules. This paper will discuss several topics related to these technology developments and development of risk based condition (integrity) assessment.

Abstract 2020 marks another challenging year for O&G sector, with the operators being in an uphill battle to survive the plunging oil price. With CAPEX rationalization underway, future field development may only be prospective via implementation of low-cost Field Development Plan (FDP). As well cost is a significant component of development CAPEX, low well cost must be pursued, by designing fit-for-purpose wells. For relatively shallow (≈2000 m-MD in meterage drilled) wells, a simple well design consisting of only two-hole sections (excluding Conductor) shall be considered. This design approach though, may require the Surface Casing to also be the Production Casing (if only Production Liner will be ran in the production hole section or if open hole completion is feasible or if cemented monobore completion strategy is adopted). This aspect of casing design (having Surface cum Production Casing) does indeed pose well integrity concerns as the quality of cement behind the Surface cum Production Casing is uncompromisable to ensure no gas can breach to surface. This paper discusses the design measures than can be incorporated into the well trajectory, cementing plan, and production surveillance in order to support the feasibility of Surface cum Production Casing concept.

The article analyses the possible influence of third-party rights infringed during construction planning on the implementation of an investment project. It analyses the process for defence of third party rights infringed during territorial planning. The focus in this process is on third party rights and opportunities to learn about possible infringement of such rights. In a construction project, judicial disputes are an unwanted risk factor, which may disrupt the entire project. It is therefore necessary to plan and apply preventive measures for the mitigation of such risk at the initial planning stage of a construction project. For that end, the article presents some principles of behaviour and actions that could help investors and third parties to solve conflicts, reduce their negative outcomes or reach an arrangement satisfactory to both disputing parties.

Purpose Construction planning for microtunneling projects is a complex process due to the high level of uncertainties inherent in underground construction and the interdependent nature of decision variables. Simulation is a suitable decision-making tool to account for uncertainties and to model complex dependencies among decision variables. This paper aims to improve microtunneling construction planning by using simulation. Design/methodology/approach This study proposes a hybrid simulation approach that combines discrete event simulation (DES) with continuous simulation (CS) for microtunneling construction planning. In this approach, DES is used to model construction processes at the activity level and CS is used to model the continuous flow of soil material in the system. Findings To demonstrate the capability of the proposed approach in construction planning of microtunneling projects, different construction plan scenarios are compared in a microtunneling case study. The results of the case study show suitability of the hybrid DES-CS approach in simulating microtunneling construction processes and the practicality of the approach for identifying the most efficient construction plan. Originality/value This study proposes a new modeling approach for microtunneling construction processes using hybrid simulation and provides decision support at the construction planning stage of projects.

The article reveals views on the purpose and direction of negative testing of special software. The research paper also provides an indicative list of questions recommended to be planned for testing using the technique of negative testing. The provisions of legal acts of Ukraine and practical experience in the field of software testing are also taken into account in the article. Negative testing is very relevant for testing special software products used in weapons. This is because the risks of error are very critical and sensitive. The main sources and causes of errors in the software are: user, input data, resources, procedures for output and storage of data, exchange with other programs or computers, operating conditions of the program, compatibility and coherence with other software. Negative testing is proposed to be used at the following stages of software use: installation, first run, authorization, data entry, software module startup, calculations, data conversion, data exchange with other systems, data storage, display information, data printing, saving settings software operation. The article states that the procedure for conducting negative testing should be carefully thought out. To do this, at the planning stage of software testing, specialists with experience in successful testing such software products are involved. It is assumed that when planning a negative test, a group of experts uses information about the program, their own testing experience and intuition of the tester. At the same time, the main efforts are aimed at creating such conditions under which the software may work incorrectly. Negative testing is planned to cause just that non-standard behavior of the program. The suggested approaches to perform negative testing are proposed to be taken into account when testing the special software that is installed at the workplaces of the Command Posts of the Armed Forces of Ukraine, as well as on weapons and military equipment.
