  • The Economic Impacts of the Gulf of Mexico Oil and Natural Gas Industry
    The Economic Impacts of the Gulf of Mexico Oil and Natural Gas Industry Prepared For Prepared By Executive Summary Introduction Despite the current difficulties facing the global economy as a whole and the oil and natural gas industry specifically, the Gulf of Mexico oil and natural gas industry will likely continue to be a major source of energy production, employment, gross domestic product, and government revenues for the United States. Several proposals have been advanced recently which would have a major impact on the industry’s activity levels, and the economic activity supported by the Gulf of Mexico offshore oil and natural gas industry. The proposals vary widely, but for the purpose of this report three scenarios were developed, a scenario based on a continuation of current policies and regulations, a scenario examining the potential impacts of a ban on new offshore leases, and a scenario examining the potential impacts of a ban on new drilling permits approvals in the Gulf of Mexico. Energy and Industrial Advisory Partners (EIAP) was commissioned by the National Ocean Industry Association (NOIA) to develop a report forecasting activity levels, spending, oil and natural gas production, supported employment, GDP, and Government Revenues in these scenarios. The scenarios developed in this report are based solely upon government and other publicly available data and EIAP’s own expertise and analysis. The study also included profiles of NOIA members to demonstrate the diverse group of companies which make up the offshore Gulf of Mexico oil and natural gas industry as well as a list of over 2,400 suppliers to the industry representing all 50 states.

The low-price environment in the oil and gas field forces operators to focus on cost-saving methods anywhere practical. Wells with longer laterals have become more prominent in the industry due to their additional contact with the formation, increased productivity and the ability to save money. However, conventional completion methods are a limiting factor due to their decreasing efficiencies with respect to lateral length and problems that thereby

The infrastructure built over decades to supply fossil fuels is the world’s largest enterprise with the largest market capitalization. Of fossil fuels, oil and natural gas make up 63% of energy usage.1 Across the energy economy, the source and mix of fuels used across these sectors is changing, particularly the rapid increase in natural gas production from unconventional resources for electricity generation and the rapid increase in domestic production of shale oil. While oil and gas fuels are essential for the United States’ and the global economy, they also pose challenges: Economic: They must be delivered to users and the markets at competitive prices that encourage economic growth. High fuel prices and/or price volatility can impede this progress. Security: They must be available to the nation in a reliable, continuous way that supports national security and economic needs. Disruption of international fuel supply lines presents a serious geopolitical risk. Environment: They must be supplied and used in ways that have minimal environmental impacts on local, national, and global ecosystems and enables their sustainability.

  • Study on Wellhead Growth in Deep Well
    MATEC Web of Conferences 77, 06003 (2016) DOI: 10.1051/matecconf/20167706003 ICMMR 2016 Study on Wellhead Growth in Deep Well Gao Baokui, Ren Jingweiand Gao Liang Department of Petroleum Engineering, China University of Petroleum Beijing, Beijing, 102249, China Abstract. Wellhead growth has occurred in many deep wells in China recently. In the paper, casing axial force and wellhead movement are calculated and compared in regard to moments that free sections of surface casing appear. The parameters considered include preliminary casing tension, free section length and change in wellbore temperature. The moment that surface casing free section comes into being has great influence on wellhead movement, so it is discussed in detail. According to comprehensive investigation on deep well and ultra-deep well accidents, wellhead growth is based on the fact that before production the cement sheath of surface casing has already failed, and during production wellhead grows up due to wellbore temperature increases. The most possible reason of surface casing cement sheath failure is bad cement job quality. Bad cement sheath cannot support casing axial loads and separates from casing. The free section of surface casing will experience large axial force cycle which is harmful to wellbore integrity. Effective measures to remedy wellhead growth is supporting the wellhead with a large base set on ground, rather than pads fixed on conductor. 1 Introduction 2 Models of wellhead growth Wellhead growth is usually occurred in thermal wells and offshore self standing platform wells. In a normal thermal 2.1 Wellbore structure of deep wells well, only production casing is connected with wellhead A typical wellbore sketch of deep well in China is drawn and in most cases the well is cemented to surface.

  • Introduction Blowout Preventer Stack Equipment
    WELL CONTROL EQUIPMENT & PROCEDURES WC-1 Introduction Preventing and, when prevention is not sufficient, respond- ing to potential uncontrolled releases of oil or gas ("blow- out") is critical to safe drilling operations. A kick is an influx of formation fluids into the wellbore. A blowout is an uncon- trolled kick exiting the well at surface. Well control is a process that begins with spudding the well and is not complete until the well is put on production and all drilling operations cease. This chapter will examine equipment commonly used in well control and processes used to control kicks of oil or gas. Blowout preventer stack equipment Annular blowout preventer The annular blowout preventer is installed at the top of the BOP stack (Figure WC-1) and has the capability of closing (sealing off) on anything in the bore or completely shutting off (CSO) the open hole by applying closing pressure. The sealing device of an annular blowout preventer is re- ferred to as the “packing element”. It is basically a do- nut-shaped element made out of elastomeric material. To reinforce the elastomeric material, different shapes of me- tallic material are molded into the element. This keeps the elastomeric material from extruding when operating system pressure or wellbore pressure is applied to the bottom of the packing element. Since the packing element is exposed to different drilling environments (i.e., drilling fluid/mud, cor- rosive H S gas and/or temperature of the drilling fluid), it is 2 Figure WC-1: Schematic (top) and photo of annular blowout important to make sure that the proper packing element is preventers.
