Low Cost Wellsite. Determination of Bottomhole Pressure from Acoustic Surveys in High Pressure Wells
Authors: Podio Augusto L. , Weeks Steve G. , McCoy James N. 
Published: December 2007

ABSTRACT
The risk and cost involved in undertaking bottom-hole pressure surveys by wireline in high-pressure gas wells, especially those which produce sour gas, often discourages obtaining information which is vital for evaluation of well performance.
Field tests have verified the accuracy of a sensitive, high-pressure acoustic instrument that enables determination of fluid levels and/or echo-time to a downhole marker, without limitation by depth, well tubulars or environment. This has opened the way for development of a diagnostic technique giving information about well pressures and fluid distribution in the wellbore without the use of downhole pressure survey tools. This Wellsite Pressure Calculation System (WPCS) is especially applicable for hostile environments, attributable to high pressure/high temperature, sour gas production, where wireline surveys involve significant risk and expense.
Results, supported by field tests involving pressure buildups under controlled conditions, indicate the calculated pressures agree with those measured by downhole pressure bombs to within the accuracy of the pressure bombs (1%) and can be used satisfactorily in buildup analysis.
A description of three sets of field tests is given, as well as the development of programs for wellsite data analysis using a portable, battery-powered microcomputer.
Oil Saturation Evaluation for EOR in a Carbonate
Authors: Cannon D. E. , Rossmiller J. W. 
Published: December 2007

Abstract
Two wells in the San Andres dolomite of west Texas were cored and logged to evaluate the residual oil saturation (S or ) for enhanced oil recovery. The log responses of both wells were very similar. One well's conventional core showed an average of 9 percent S or and the o ther well's pressure coreshowed 30 to 40 percent S or . A means of tying the log and core information together was needed where the in-situ S o and formation water resistivity (R w ) values were questionable. Core values of m were chosen as the tie. They were compared to back-calculated m values from various logs to confirm R w and S o . Through-casing gamma spectrometry carbonoxygen values of 1 - S w (S o ) were used to further confirm the final S o . In the iteration process of bringing core and log answers closer together, it was found that the dolomites were very laminated and the dual laterolog data were being adversely affected by shoulder beds. Much of what appeared to be invasion was a shoulder-bed effect. The invasion-corrected value (R t ) was reduced in the permeable zones to 0.7 of the original value when shoulder-bed corrections were made prior to invasion corrections. Detailed core analyses and computer-processed logs were brought into reasonable agreement.
The Operator-Contractor Relationship—Gains and Losses, 1982 to 1984
Authors: Combes J. D. 
Published: December 2007

ABSTRACT
Through the last several years, the petroleum drilling industry has experienced both a boom and a slowdown. This relatively low supply and high demand for rigs in the " boom times" was a contractor's dream. Now the tide has turned, whereby the industry has regressed producing a slowdown. The operator has become more selective in the rig selection process. This selective ness, on the part of the operator, has forced the contractor to become competitive through cost cutting and manpower reductions. How does this effect the drilling industry? Who's to gain? or Who's to lose?…the operator or the contractor?
Construction and Certification of a U.S. Flag Jackup for Norwegian Waters
Authors: Covellone T. C. , Thorson J. A. 
Published: December 2007

ABSTRACT
In 1981 Global Marine Drilling Company contracted for the construction of a large jackup drilling rig capable of year around operation in very severe, relatively shallow water environments, such as in the North Sea and Eastern Canada. This rig was delivered in 1984 and is named the Glomar Moray Firth I. This rig is the first non-Norwegian flag MODU to fully comply with the rules of the Norwegian authorites – generally accepted as being some of the most severe in the world. Integrating the regulatory body requirements of four countries (Norway, United Kingdom, Canada and the United States) and the IMO and SOLAS rules, proved to be a extensive technical and logistical task. The highlights of this effort are addressed in this paper.
Operator Engineered and Maintained Mud Systems: A Way To Reduce Costs and Improve Drilling Efficiency
Authors: Lee L. G. , Bernard H. J. 
Published: December 2007

ABSTRACT
In August 1982, ARCO Oil and Gas Company's South Permian District, in a successful effort to reduce costs and improve the efficiency of drilling operations, began purchasing mud materials without the services of the vendor's mud technician. ARCO's drilling personnel were equipped with API standard mud testing equipment and trained in drilling mud practices. Because of this, the District received lower pricing from vendors and greatly improved mud cost controls. Two main reasons for this policy were these:To reduce drilling costs andTo increase drilling personnel's knowledge of drilling mud design and applications with its relationship to other aspects of drilling.
This paper briefly discusses the success of ARCO Oil and Gas Company's program of operator-engineered and maintained mud systems from August 1982 to August 1984 and compares costs before and after the program was initiated.
Hole Cleaning: Some Field Results
Authors: O'Brien T. B. , Dobson M. 
Published: December 2007

ABSTRACT
When the hole heaves, falls in or is plagued with excessive fill, much time is lost reaming and redrilling. Typically six to ten days of washing and reaming are required to remove cavings if the drill string does not get stuck. This paper will be a report of several field applications of methods used to clean a hole.
Fluid and well equipment conditions required for proper hole cleaning are given as is the basis for their selection.
Hole cleaning problems and solutions in various hole sizes, different types of rocks and different drilling fluids are described. Examples are largely from the Delaware, and Anadarko Basins.
Very severe hole caving problems have been cured in a short time when the proper conditions are met.
The Spiral Flow Cylindrical Mud Mixer
Authors: Stinson D. L. , Underwood G. E. 
Published: December 2007

SUMMARY
The Spiral Flow Cylindrical Mud Mixer (SPCMM)* is a unique system recently developed for mixing large volumes of mud quickly under controlled conditions. Its streamlined internal shape allows regular flow by minimizing obstructions. A well organized flow pattern from the outside walls of the mixer into the centrally located suction eliminates dead spots and promotes uniform mixing of the contents. Field tests indicate that this system will mix mud approxiamtely four times as fast as other existing systems. The speed of mixing up to this time has been determined by the limitations of adding materials to the mixer, and not the speed of the mixing action of the mixer.
This new system may be applied whenever an operator needs large volumes of mud with carefully controlled properties to solve well control problems. Plant tests have shown that this mixer will produce 214 bbl. of 17+ lb/gal. mud in a 24 hour period.
The SFCMM* is a unique mixer that provides more uniform mud at higher rates than that provided by other mixers available.
Use of the Engineering Simulator for Drilling for Evaluating and Designing Drilling Rigs
Authors: Brett J. F. , Yoder D. L. 
Published: December 2007

ABSTRACT
Drilling personnel typically base the selection of a Drilling Contractor and rig on their subjective evaluation of how well various rig components will meet their envisioned drilling needs. This evaluation process involves rating the capabilities of the drawworks, mud and solids control system, mud pumps, tubulars, power generation equipment, and ancillary equipment such as blow-out preventers, choke manifolds, automatic driller, and instrumentation. Consideration must also be given to the type of geology that the planner expects to encounter. However, the true performance or capability of the selected rig is not known until it is contracted and used to drill a well. Many times the advertised capability of the rig is not achieved in the field.
An Engineering Simulator for Drilling (ESD) has been developed that can simulate the operation of any SCR type drilling rig in any type of drilling environment. The simulator has been used to compare different equipment for specific drilling programs and has predicted which rig would be the best rig to drill the well. The simulator has also been used to up-grade the design of existing rigs to optimize their performance.
This paper presents an overview of the drilling rig simulation algorithms and how they are used to emulate an actual drilling rig. The paper also gives examples of how the simulator is used to evaluate rig capabilities, and how this ability to evaluate rigs, with an unbiased systems approach, can be used by operators to select rigs on a performance basis.

Applications of Measurements While Drilling (MWD): Development of the East Breaks Field, Offshore Texas
Authors: LeGros F. W. , Martin C. A. 
Published: December 2007

ABSTRACT
In October of 1982, after drilling the seventh well on the Cerveza platform in offshore Texas waters, nearly four days were spent attempting to record wireline logs. Getting wireline logs to total depth was typical of problems on previous wells in this area. Measurements While Drilling (MWD) utilizing resistivity and gamma ray, was evaluated on the eighth well and has been used successfully on the subsequent eight wells to date. This initial use of MWD for geological evaluation led to further applications reagarding drilling optimization and directional control.
Practical Rig-to-Office Data Communications
Authors: McCoy R. S. 
Published: December 2007

ABSTRACT
In recent years, Data Communications has become one of the fastest growing technologies. Linking computers with telemetry, and founded upon the clear and obvious perception that accurate and timely information is of great value to the appropriate users, Data Communications has been eagerly accepted by industries that depend upon clear visibility and control of operations, insightful interpretation of available data, and critical decisions based upon economic objectives.
Historically, oil companies have been conservative in adopting systems and techniques that alter or impact traditional oilfield processes that affect the collection, review and reporting of oilwell drilling data. This reluctance has been based upon a lack of understanding of new technology, a natural concern for the problems of implementing that technology with a minimum of disruption, and a legitimate concern for justifiable cost.
This paper provides a brief overview of the potential impact of Data Communications technology on the oil industry. Based upon experience in the oilfield, it addresses the practical aspects of implementing this technology both at the rig and in the office. The process of involving and gaining the cooperation of wellsite personnel is discussed in terms of real-time and "batch" transmission of drilling data, and the extent to which computer expertise is required. Special considerations of wellsite security and office-to-rig Data Communications are also addressed.
Perhaps the most critical aspect of Data Communications concerns economic and operational justification. This paper suggests justification for Data Communications in terms of reduced drilling costs and improved well control.

The purpose of this paper is to try to present an industry picture which is based upon trends and statistics that may enable you to see what the overall future outlook may be for the petroleum engineer. No attempt is being made to quantify you as individuals. The obligation which you as an individual have, and the experience and success which you may achieved is pretty much up to you. The prime objective of engineering training is to gain knowledge and, through the application of such knowledge, to make possible the production of the required supply of minerals and raw materials and to utilize such materials to provide a better product to the ultimate consumer at a lower cost. The participation of the petroleum engineer in industry is governed by knowledge, desire, and effort, or, perhaps, they should be re-arranged with effort heading the list. The value of the petroleum engineer is dependent upon what he achieves for himself and for his employer. Petroleum engineering is a relatively new field. In 1900 there were only 3000 engineers classed as metallurgical and mining.

Authors: Schmitt G. , Steinmetz D. , Engels D. , Bruckhoff W. 
Published: December 2007

ABSTRACT
The resistance of various low alloy steels to mass loss and localized attack under conditions of sweet gas production was investigated in artificial production water at 70–130°C under 4–6 bar CO2 at flow velocities of 3.5–6.2 m/s. Experimental conditions were found for reproducible production of pitting and erosion corrosion and its effective inhibition by dissolved lead salts.
Thermally Stable Polymeric Gellant for Oil-Base Drilling Fluids
Authors: Patel A. D. , Salandanan C. S. 
Published: December 2007

ABSTRACT
A polymeric oil gellant, which imparts thixotropic properties to oil-base drilling fluids has been developed. Present day state-of-the-art additives, such as organophilic clays, various soaps, asphaltic materials and mineral fibers which are used to impart gel structure to oil-base muds have certain limitations. One of the major shortcomings is thermal instability. In addition, some of these additives contribute to undesirable solids buildup. To minimize these problems, we have developed a novel oil-dispersible copolymer from styrene-butadiene and functional monomers. This novel oil-base drilling fluid additive provides a drilling fluid which exhibits a variety of highly desirable properties, such as elevated yield point and a more effective gel structure. This novel additive does not significantly increase the plastic viscosity of the drilling fluid.
Modeling of Permeability Reducing Vertical Conformance Treatments
Authors: Tsau J. S. , Hill A. D. , Sepehrnoori K. 
Published: December 2007

ABSTRACT
Chemical treatments (usually polymer gels) are commonly applied to improve the vertical conformance of oil reservoirs by selectively reducing the permeability in some zones near the well. The results of such treatments have been sporadic and unpredictable; The objective of this work was to define those reservoir characteristics which lead to successful treatments and to provide guidelines for the application of conformance treatments by modeling them with a reservoir simulator.
Several cases have been run to identify the reservoir properties that strongly influence the outcome of a conformance treatment. Among the conclusions that have been drawn from this study are: 1. A low level of reservoir crossflow is conducive to a successful vertical conformance treatment; 2. The contrast in the permeability-thickness product of the reservoir layers is a useful parameter in identifying treatment candidates; 3. Vertical conformance treatments reduce the amount of injected water needed to recover a given volume of oil; and 4. Little sensitivity to the level of permeability reduction is observed as long as the treated region was reduced to a permeability as low as that in the low permeability layer.

ABSTRACT
Power consumption in rod pumped wells is related to the power used in lifting fluid column loads as well as overcoming dynamic effects and power losses that occur in mechanical equipment. A testing system has been designed and a computer program written that locates and quantifies system losses, comparing them to the power required to drive the entire system.
Operating Experience With a Two-Stage H2S Scrubber Using Caustic Soda
Authors: Siemak J. B. , Gelbs M. 
Published: December 2007

ABSTRACT
Hydrogen Sulfide (H2S) and Carbon Dioxide (CO2) are natural occurring gases produced along with crude oil in many oil fields in California. Natural gas when highly contaminated with these gases has very little commercial value and also causes safety, environmental, and corrosion problems in pipelines and equipment. It therefore must be treated before disposal or blending. The Bremer Fee lease multi-stage scrubber facility was built to remove H S from well-produced sour gas streams, so that the resultant sweet low Btu gases could be disposed off by venting.
On the Equivalence of a Hot Water and Gas Drive to a Steamdrive
Authors: Doscher T. M. , Hosseinmardi M. K. , Baghdikian S. Y. 
Published: December 2007

Abstract
The hypothesis that the recovery of oil by a steam drive could be duplicated by a combination hot water and non-condensible gas drive has been confirmed in bench scale, non physically scaled experiments. Despite the inherent limitations of such laboratory experiments, it is believed that the results point to the potential of a new powerful enhanced oil recovery process for both viscous and high gravity crudes.
The Use of Density Control Foam Fracturing for Selective Proppant Placement in the Bartlesville Formation
Authors: Barber P. L. , Themig D. J. 
Published: December 2007

ABSTRACT
A major consideration in fracture stimulation of the Bartlesville formation in Eastern Oklahoma is the lack of competent barriers to prevent downward fracture growth out of the oil-producing interval and into the water-producing interval. This has resulted in sizeable increases in water production with little or no effective stimulation of oil production.
Attempts have been made to design stimulation treatments to minimize the downward fracture growth through the control of job size and pumping rates. This approach has produced some successful fracture treatments as will be discussed in this paper, but evidence indicates that in many cases proppant has been placed in the water-producing interval despite these measures.
This paper will present a different approach to minimizing water production resulting from hydraulic fracturing. It is based on the assumption that downward fracture growth cannot be sufficiently controlled using existing procedures. This approach will present the use of density controlled foam fracturing to selectively place proppants in the upper portion of the fracture adjacent to the oil-producing interval. Included are case histories of density control fracture treatments as well as those of conventional treatments performed in the Bartlesville. Also included are radioactive tracer surveys to support selective proppant placement using a density controlled foam fracturing process.
