Abstract In developing the Doris Mannville Coal Bed Methane (CBM) gas field near Fort Assiniboine, Alberta, the Nexen exploitation team encountered many unforeseen artificial lift challenges using Electric Submersible Pumps (ESPs). High failure rates and short pump run times made forecasting of production ...
Abstract In view of low possibility across fractures, low controlled reserve for a single well, fast production decline, poor development performance for conventional horizontal well and directional well in the liaohe buried-hill migmatitic granite reservoir with characteristics of deep buried-depth, ...
Abstract The advent of highly deviated and horizontal well completions has created the need for a new line of service tools that do not rely upon gravity for the setting and retrieving of downhole tools. When using reeled tubing in downhole applications, in particular highly deviated or horizontal ...
Abstract Federal and state permits for North Slope oil development stipulate that sites used for exploration and production operations must eventually be returned to a condition acceptable to the regulating agencies and the landowner. In cooperation with the University of Alaska Fairbanks and regulatory ...
Abstract Regulators outside of the United States either have not set cleanup goals for Total Petroleum Hydrocarbons (TPH) and other chemicals in soil, or they have proposed very low concentrations based on reviews of European and North American regulations. Soil TPH or oil and grease cleanup levels ...
Abstract A total of six high rate water packs were installed in two wells utilizing a single trip, multi-zone gravel pack technique. The multi-zone gravel pack tool system allowed the installation of multiple gravel packs with a single run into the wellbore.1,2,3 This gravel pack system was chosen ...
This paper was prepared for presentation at the 1999 SPE/EPA Exploration and Production Environmental Conference held in Austin, Texas, 28 February-3 March 1999.
Abstract The stickiness factor is an empirically derived number strongly related to the chances of freeing stuck pipe in a well. The number is defined by the following equation: Stickiness Factor = .....................................(1) where: is the maximum angle in the open hole (degrees); OH ...
Abstract The requirement for sub-sea soils data is paramount for the siting of gravity structures, pile founded structures, mobil drill rigs, selection of pipeline routes and depths of burial, anchoring of vessels, running of preconductors and a myriad of other associated problems. problems. Properties ...
Abstract Downhole plugs are now commonly used for isolating multistage stimulation jobs. These plugs allow for more timely completion, yet they must also be removed in a timely fashion. This paper discusses how coiled tubing (CT) can efficiently mill out these plugs. The three case histories in this ...
Abstract Unocal is the largest producer of natural gas in the Gulf of Thailand. Unocal is faced with finding the most cost-effective way to handle produced water from its oil and gas operations to minimize its impact on the environment. Two options were considered for handling the water: water treatment ...
Abstract Occupational Health (OH) Inspection Guidelines for Remote Upstream Operations was initially developed by the parent company for inspection of remote upstream operations e.g. exploration rigs at a remote site. This OH Inspection Guideline had been previously presented at the Sixth SPE International ...
Abstract Recently, public attention has been directed at global warming, greenhouse gases and overall environmental quality in the United States and around the world. Fuels production inherently produces carbon dioxide as a byproduct and the public and the legislature have deemed it necessary to consider ...
Abstract The Nord Stream Pipeline (a two-pipeline system) from Russia to Germany through the Baltic Sea was constructed during 2010-2012. In Swedish waters, subsea post-lay trenching by ploughing was carried out at minimum 4 km distance to two Natura 2000 areas1, which was considered by the environmental ...
SPE Member Abstract This paper introduces a unique drill pipe design concept proposed primarily for high angle/horizontal service. The design consists of a pipe joint, the middle two-thirds of which are light-wall and has an outside diameter only slightly smaller than the tool joint. Handling space ...
SPE Members Abstract This paper discusses the methodology and the two associated spreadsheet templates developed to evaluate and quantify the drilling performance in both international and domestic operations for Amoco Production Company. This methodology allows the timely monitoring and analyzing ...
Abstract Because casing integrity is vital to the success of sidetrack, workover, recompletion, and enhanced-recovery operations, it is important to use reliable means of examining casing downhole. Modern casing inspection tools provide valuable diagnostic information for planning future work in a ...
Abstract The need of cutting the costs of new oil wells in the San Jorge Basin led YPF S.A. to study the option of reducing well diameters. For an effective cost reduction, it was necessary to be able to case the hole with diameters smaller than 4.5 inches. The problem of a completion in 3.5 inches ...
Abstract Solids as well as the liquid phases of drilling muds invade and interact with reservoir formations that contain oil and gas. These invasion and interactions change the formation permeability and in extreme cases may stop the fluid flow from the reservoir to the wellbore. The damage caused ...
Proposal This paper provides a summary of access and access-related legal issues for operating personnel covering access to and on oil and gas leases on federal public, Indian, state, and private lands. The author admits to a decidedly western orientation and perspective, as the western experience ...
