Distinguished Author Series articles are general, descriptive representations that summarize the state of the art in an area of technology by describing recent developments for readers who are not specialists in the topics discussed. Written by individuals recognized to be experts in the area, these ...
Abstract The evolution of coiled tubing technology has brought many unique wellservice solutions to the oil and gas industry. Concentric Coiled Tubing (CCT)is a recent development which has opened the door to a whole range of new wellservicing capabilities. One of these techniques incorporates concentric ...
Huntoon, George G., SPE, Amoco Production Co. Summary Successful development of the Tuscaloosa trend in Louisiana has required unique completion practices to produce the trend's deep sour formations. Amoco's operations in the Tuscaloosa formation are between 16,000 and 21,000 ft [4877 and ...
Summary Black asphaltenic-type material removed from the drillstem at 5945 m [19,505 ft] in Well Gravberg-1 from the Precambrian granite, Siljan, Sweden, was investigated to determine its origin. The chemical characterization showed that this material contains small amounts of hydrocarbons maximizing ...
Summary The Genesis project was ChevronTexaco's first Gulf of Mexico deepwaterdevelopment project and the first industry project to use spar technology fordrilling, completion, and production operations.1,2This paper discussesthe unique results and lessons learned through the first 4 years of ...
General At present, formal geological training provided by the oil and gas industry ranges from comprehensive to largely non-existent. In general, the major companies provide the best training and the juniors the poorest. Exceptions to the rule certainly exist, however, it is generally recognized that ...
Abstract This paper discusses coil tubing operations performed on three sour gas wells in which coil tubing was used to retrieve plugs where conventional wireline methods proved ineffective. All three wells are located in the Obed Field of Alberta, which produces high pressure sour gas. The field ...
Summary. New features of polymer rheology in porous media were observed when hydrolyzed polyacrylamide (HPAM) solutions were flowed through sandstone, gravel packs, and glass-bead packs at high rates. Independent measurement of elongational viscosity, , with a ductless-siphon technique demonstrates ...
Summary The redesign solution for the batch-drilled wells remaining after the deformation of the Marlin Well A-2 production tieback and tubing was vacuum-insulated tubing (VIT). VIT implementation, however, required a number of computational and experimental innovations. To ensure well survival, a ...
Summary Design and development of superior drilling and drill-in fluids, and the assessment of the effectiveness of mudcake cleaning from the borehole wall by cleaning systems, require a good understanding of the fundamental phenomena associated with the erosional behavior of mudcakes formed by different ...
Abstract The oil-bearing Belly River pools of the Pembina area of Alberta were discovered in the search for Cardium oil and developed under skepticism by many operator. The indicated high connate water saturation, the presence of swelling clays within the formation and the lack of readily available ...
Summary Barium sulfate scale deposition in the near wellbore, perforations, or production tubing has severely affected well productivity in many North Sea Fields. This is due to the co-mingling of the sulfate-rich seawater used for reservoir sweep with formation water containing high concentrations ...
Summary The thermal and mechanical loading of oceanic hydrate-bearing sediments (HBS) can result in hydrate dissociation and a significant pressure increase with potentially adverse consequences on the integrity and stability of the wellbore assembly, the HBS, and the bounding formations. The perception ...
Summary. The BORE system is a drilling reporting and evaluation data system specially designed for drilling engineering. It reports drilling information from the rig site to the drilling department office and to license partners and authorities. The system provides valuable well information on previous ...
Summary. A computer program based on the continuity and momentum equations for prediction of the flow of gas through low-permeability porous media was developed. This program uses the FORSIM code, which porous media was developed. This program uses the FORSIM code, which is based on the method of lines ...
Summary Daqing oil field is one of the earliest to develop displacement technology by polyacrylamide (HPAM). One tonne of polymer can increase 100 to 120 tonnes of oil; the recovery increases from 40% (OOIP) to 50% (OOIP). In view of the geological and physicochemical characteristics, a series of technologies ...
Abstract In a time of declining production and increasing demand, geoscientists are challenged more and more often to develop new techniques and strategies for evaluation and appraisal of increasingly complex and deeper reservoirs. This paper describes the subsurface challenges and how, through optimized ...
Summary Two new polyacrylamide processes for water control in producing wellsimprove the efficiency of conventional polyacrylamide treatment withoutinducing any risk of well plugging by crosslinkers. Treatment plugging bycrosslinkers. Treatment of a gas-storage well strongly decreased waterproduction ...
Summary At Prudhoe Bay, Alaska, nonrig tubing repairs have become a viable alternative to rig workovers (RWOs). They provide economic remediation for wells with production tubing by ""A?? annulus communication. Electricline (EL)-set straddles can eliminate tubing communication at a significant cost ...
Summary From 2010 to 2012, two parallel gas pipelines (the Nord Stream Project) were installed in the Baltic Sea between Vyborg in Russia and Greifswald in Germany. The pipeline system will enable an annual transport of 55 billion m3 (bcm) of natural gas from the large Russian gas fields to the European ...
