Increase the return of your investment! Naturally, everyone is interested in doing this. The object of this paper is to discuss some recent developments of accessories which may be adapted to your present sucker rod pump which will make it better suited for the well condition. All of these accessories may be adapted to most of the conventional sucker rod pumps, and will increase their efficiency or service life, thus increasing the return on your investment.

As a result of increasing emphasis on cutting waste, streamlining operations and improving recoveries, the use of the short cycle adsorption unit has become a widely accepted method of processing gas streams.

The production of high gas liquid ratio (GLR) wells has been a problem for oil producers since the first sucker rod pumping systems (SRPS) were installed. This paper examines three key factors in improving SRPS efficiency in high GLR wells. These include pump design, rod string stability and field operations. Although pump design and field operations are well documented, an attempt is made to clarify these areas. Also, new light is shed in the area of rod string design with special consideration of rod buckling and its associated problems.

This paper describes field implementation of a newly-developed downhole injection @I-II) tool for same-well-bore, simultaneous-gas-production-and-water-disposal, for water drive oil and gas formations with water coning problems. The method enhances the production rate of water-free gas while minimizing disposal cost and eliminating problems associated with water disposal. (Fig. 1)

The accurate determination of residual oil saturation is of critical importance in evaluating the feasibility of applying an enhanced recovery process in a specific reservoir. The economics of the new improved recovery processes are extremely sensitive to the residual oil saturation in place at the beginning of the project and to the conformance expected to be achieved within the project area. This means that both the amount and the distribution of oil remaining in place must be determined to adequately evaluate the potential of the venture.

Incident at Morales involves a variety of ethical issues faced by a company that wants to quickly build a plant in order to develop a new chemical product to gain a competitive edge over the competition. This 36 minute video developed and distributed by the National Institute for Engineering Ethics will be shown.

The accumulation chamber is an efficient method of oil production by gas lift. The fundamental purpose of the chamber is to provide additional storage space in the well bore during intermitting gas lift operation. Various formulae are offered for the calculation of chamber design. It is shown by theoretical analysis, supported by field data, that the use of the gas lift chamber principle improves production.

In the reaction of formation rock with acid, as in a matrix acidizing treatment, varying quantities of insoluble fines are released or otherwise dislocated by the flow. Also, normal reservoir flow can break or dislodge fragile clays and minerals present on the pore linings. If allowed to settle and accumulate, these fines have the capability of plugging pore throats when disturbed in mass upon the return flow of the treatment and formation fluids.

A case study was conducted on San Andres Formation wells to evaluate the benefit of focused efforts to optimize hydraulic fracturing treatments for improved well productivity. The application of conventional fluids and techniques had provided lower than expected post-treatment productivity and a rapid decline rate, suggesting that fracture conductivity was less than optimum. Several recently introduced hydraulic fracturing technologies were combined to develop an integrated treatment design and application package to improve well production.

In the present state of the oil and gas economy, operators have been searching for ways to increase production and cash flow with no gamble and with an AFE expenditure that gives their money back and a good return on their investment the first year.Operators are finding that one sure way to increase production and cash flow on producing wells is to relieve the RESTRICTING BACK PRESSURE on the producing formation on wells which respond to this technique.

The increasing recognition of Plunger-Lift as a viable method for producing many wells, has brought a number of changes to the technology involved. The importance of proper plunger-lift performance criteria (as reported in an earlier SPE paper) has been recognized and steps taken to incorporate this information into modern day control systems. This paper discusses the usage of plunger velocity in establishing operating cycles for gas wells and for oil wells.

Removal of emulsified oil from waste water is receiving renewed attention in light of best practical control technology and treatment level requirements. This paper presents a discussion of the induced-gas flotation process as a method for cleaning waste waters by removing suspended contaminants using, froth floration. The origin of the process is briefly reviewed and a comparison is made to dissolved-air flotation showing that the two processes have both similarities and differences. A method of inducing and dispersing gas bubbles into water with individual cell mechanisms is discussed.

Separation of oil and water has been important in crude oil production historically. Some oils and produced brines do not mix with enough stability to seriously complicate handling. Water in oil emulsions are more common than the oil in water type, often called "reverse emulsions" or "O/W"S". We will see, however, that there are problems in clarifying produced water, or more specifically removing trace amounts of suspended oil and solids from this water. This discussion will bear upon resolving the more stable dispersions of oil in water that are encountered in oilfield production practice.

The most valuable assets held by any company are the men and women who do the work. The job of properly defending these assets equals, or transcends, all other responsibilities of supervisory personnel. Responsible industrial organizations recognize the economics involved in protecting employees and are seeking individuals with ability to promote safety.

Statistics demonstrate that there is big money in oilfield theft, approximately half a billion dollars yearly. Yet, most operators would be hard pressed to itemize their actual assets or verify ownership of stolen or lost equipment. This paper discusses the lack of internal control prevalent throughout the petroleum industry and identifies, through initiation of company policy and procedures, methods to both minimize oilfield theft and maximize cost-effective loss prevention accountability.

Waterflooding concepts in carbonate reservoirs of West Texas and New Mexico have changed drastically in recent years. The original flood designs for many waterfloods called for peripheral water injection with minimal interior injection. The use of generalized geologic correlations or averages of rock properties in the design and execution of these projects led to delayed and inefficient flood response.

Infill drilling in conjunction with waterflooding is being used to accelerate production and improve recovery efficiency. Many authors have discussed the reasons for infill drilling and the factors which affect the success of an infill drilling project.I,2,3,4,5,6 Reservoirs are heterogeneous rather than homogeneous. Van Everdingen1 related this to spacing and infill drilling. He noted that the East Texas field has been developed on a five-acre spacing. Recovery in this field with close spacing will be about 87% whereas other fields usually average 30%.

This paper presents oil-water inflow performance relationships (IPR) for water drive reservoirs above the bubble point. A wide range of rock and fluid properties, relative permeability curves and initial water saturations has been considered. The effect of a skin region around the wellbore is also included in the analysis. The general theory and application of pressure-production relationships have been discussed.

Over 40 years ago, the late President Hoover set forth a creed which is perhaps even more applicable today than when he said: "It is only through the elimination of waste and the increase in our national efficiency that we can hope to lower the cost of living, on the one hand, and raise our standards of living, on the other. The elimination of waste is a total asset. It has no liabilities."" This is the creed by which we in the oil industry are trying to live when we attack the problem of corrosion losses or waste in oil and gas producing equipment.

The Injecta-Box

The Iatan East Howard Field is located in eastern Howard County, Texas. Production is commingled from the San Andres, San Angelo and Clearfork zones. Pressure support in the field is provided by waterflood. Injectivity into these zones was poor due to the buildup of iron sulfide and biomass. Several methods were used to cleanup this buildup. The first method used was to cleanout the wellbores with 15% acid and 14% sodium hypochlorite (bleach), utilizing a coiled tubing unit. The second method was to pump bleach and acid into the injection system, which would in turn be pumped down the wells.

An innovative patented casing plunger offers production increases in Panhandle reservoirs. Several years ago, casing plungers were introduced to Panhandle oil & gas reservoirs. While several applications responded well, others were limited by wellbore conditions and reservoir fluids. Those problems have been addressed in a recently patented casing plunger, providing substantial increases in daily production and recoverable reserves.

During the de-watering phase of typical Black Warrior Basin coalbed methane wells, an artificial lift method is needed to produce large volumes of water yet. have the ability to handle a moderate amount of produced solids such as coal fines and frac sand. In response to this scenario, the Coleman Pump Company developed a free style jet pump with a design specific to the problems encountered during coalbed dewatering operations. The unique design of flow passages in the pump allows retrieval of a very small portion of the pump while still providing a greater than normal flow capacity.

To gain a better understanding of the significance of insert rock bits in today's drilling, it is important to review the evolutionary process of the entire rock bit development. Modern-day rock bit technology began in 1909 with the introduction of the first rotary cone rock bit. Prior to this time, the use of the rotary drilling process had been limited to soft formations because harder formations were difficult or impossible to drill using the scraping action of the drag bit. The rotary cone bit, then, enabled the industry to drill much harder formations than previously possible.
