Significance The Department of the Interior on May 11 gave Shell conditional approval to drill in Alaska's Chukchi Sea. Most supermajor oil companies have cut capital expenditure in the wake of the recent fall in oil prices, but Shell views developing Arctic resources as essential to ensuring energy security in future decades. The company expects to spend 1 billion dollars on Arctic exploration this year. Impacts The development of Arctic offshore oil and gas fields is not currently economic, nor is there unmet demand. However, this project will provide Shell with the opportunity to refine exploration and production capacity. This will set the groundwork for future expansions in these risky geographies. An environmental accident would cause massive reputation harm, and curtail further exploratory drilling in the region.

Gas Balance

Subject Gas sector update. Significance Despite sharp reductions in oil companies' global exploration and production, Egypt is attracting multi-billion-dollar fast-track upstream oil and gas investment. Cairo has already made progress in addressing key imbalances in its energy sector, and succeeded in reducing arrears to oil companies. Boosting upstream oil and gas production will eventually help stabilise the budget. Impacts Egypt's gas balance could turn positive by 2020, reducing the country's demand for LNG and oil product imports. Incentives for renewables, particularly solar power, are a likely path for diversifying the energy mix and stemming domestic gas demand. The government is likely to remain committed to generous PSAs. It will also probably advance domestic gas pricing reform to maintain the upstream sector's current momentum.

Subject Kurdistan Region of Iraq petroleum sector. Significance The Kurdistan Region of Iraq (KRI) petroleum sector has struggled to make progress in the context of local political and economic crises, the continuing fight against IS and some disappointing geological findings. Oil production is stagnant at around 600,000-650,000 barrels per day (bpd). Owing to persistent budgetary shortfalls, payments to international oil companies (IOCs) have faced delays. Impacts The defeat of Islamic State (IS) could open up potential oil and gas blocks in the Nineveh plains and around Kirkuk. The risk of conflict between Kurdish and Baghdad government forces over disputed oil and gas fields will rise. Worsening conflict in the Kurdish south-east of Turkey could endanger oil (and future gas) exports.

Offshore Operations

As onshore oil and gas deposits are becoming more difficult to locate, and as the world demands for energy continue to increase at an alarming rate, oil companies are channeling much of their exploration activities towards offshore operations, and in particular, towards operations centered off Canada's coast lines. Because of the environment, offshore drilling presents problems which are novel to the onshore-geared oil industry. J. M. Killey discusses in detail many of the considerations involved in drafting the offshore drilling contract, concentrating on problems such as the liability of the various parties; costs; scheduling; pollution; conflict of laws; etc. Similarly, he discusses service contracts (such as supply boat charters; towing services; helicopter services; etc.^ which are necessity to the operation of an offshore drilling rig. To complement his paper, the author has included number of appendices which list the various considerations lawyer must keep in mind when drafting contracts for offshore operations.

Floating production, storage and offloading systems (FPSOs) have been widely used for the development of offshore oil and gas fields because of their attractive features. They are mostly ship- shaped, either converted from existing tankers or purposely built, and the hull structural scantling design for tankers may be applicable to FPSOs. However, FPSOs have their unique characteristics. FPSOs are sited at specific locations with a dynamic loading that is quite different from those arising from unrestricted service conditions. The structures are to be assessed to satisfy the requirements of all in-service and pre-service loading conditions. The fundamental aspects in the structural assessment of FPSOs are the buckling and ultimate strength behaviors of the plate panels, stiffened panels and hull girders. The focus of this paper is to address the buckling and ultimate strength criteria for FPSO structures. Various aspects of the criteria have been widely investigated, and the results of the design formulae proposed in this paper have been compared to a very extensive test database and numerical results from nonlinear finite element analysis and other available methods. The procedures presented in this paper are based on the outcomes of a series of classification society projects in the development of buckling and ultimate strength criteria and referred to the corresponding classification society publications.

Geological Society Memoir 52 records the extraordinary journey of more than 50 years that has led to the development of some 458 oil and gas fields on the UK Continental Shelf (UKCS). It contains papers on almost 150 onshore and offshore fields in all of the UK's main petroliferous basins. These papers range from look-backs on some of the first-developed gas fields in the Southern North Sea, to papers on fields that have only just been brought into production or may still remain undeveloped, and includes two candidate CO2 sequestration projects.These papers are intended to provide a consistent summary of the exploration, appraisal, development and production history of each field, leading to the current subsurface understanding which is described in greater detail. As such, the Memoir will be an enduring reference source for those exploring for, developing, producing hydrocarbons and sequestering CO2 on the UKCS in the coming decades. It encapsulates the petroleum industry's deep subsurface knowledge accrued over more than 50 years of exploration and production.

And Storage

Floating production, storage and offloading systems (FPSOs) have been widely used in the development of offshore oil and gas fields because of their many attractive features. These features include a large work area and storage capacity, mobility (if desired), relatively low construction cost and good stability. They are mostly ship shaped, either converted from existing tankers or purpose built. The hull structural scantling design for tankers may be applicable to FPSOs; however, FPSOs have their own unique characteristics. FPSOs are located at specific locations with a dynamic loading that is quite different from that arising from unrestricted ocean service conditions for tankers. It is also noted that the wave conditions in recent FPSO applications may be very complicated when operating in areas such as those offshore West Africa and offshore Brazil where both seas and swells exist and propagate in different directions. In this paper, the unique FPSO operational aspects, especially the load assessment due to on-site environments will be described. The methodology of handling complicated wave conditions in fatigue assessment will be addressed. Special considerations for converted FPSOs, which need to take into account their operational history as a trading tanker and low cycle fatigue due to FPSO operations, will also be introduced. Case studies will be presented and appropriate analysis methodology will be summarized. The methodology has also been adopted by ABS Guide, see ABS [1].

The Relationship

Purpose Project failure is the result of one or a combination of several causes of risk factors that are very important to identify for effective performance. This study aims to focus on studying the fundamental relationship between internal risk factors and the negative effect on oil and gas project success in Yemen using the partial least square structural equation modelling (PLS-SEM) method. Design/methodology/approach Data collection was carried out using a formal questionnaire survey of the oil field sector in Yemen by companies involved in mega-oil and gas construction projects. A hierarchical model for determining causative internal risk factors and their effects was developed and evaluated using SEM method by SmartPLS3 software technology. Findings The findings of analyzing model indicate that all categories have a significant effect on project success, while the most significant affected categories in the internal risk factors are project management factors, feasibility study-design and resources-material supply with a path coefficient value of 0.213, 0.197 and 0.186, respectively. Moreover, for the hypotheses test, the positive relationship means that all experimental hypotheses are accepted according to path coefficient value analysis. In addition, the internal risk factors research model shows the ranking of effects on project success starting with project stoppage (loading factor 0.841), cost overruns (loading factor 0.818), time overruns (loading factor 0.726) and project target failure with loading factor 0.539. Research limitations/implications The research was limited to the oil and gas construction projects in Yemen. Practical implications Interpreting the relationship between internal risk factors and their impact on the success of construction projects in the oil and gas sector will assist project team and oil companies in developing risk response strategies and developing appropriate plans to mitigate the effects of risks, which is presented in this paper. Originality/value The paper explains the relationship between cause and effect of internal risk factors in oil and gas projects in Yemen, and is expected to be a guideline for the oil companies and future academic research in the risk management area.
