Wireless Communications Based Gauge System For Artificial Lift System Optimization

The complexity and cost of exploring for oil and gas has increased significantly in the past few years due to Intelligent Wells, Multilaterals and Heavy Oil field developments. New challenges for drilling, completing, producing, intervening in a well, environmental regulations, and wide swings in the price of oil have changed the role of technology in the oil fields. The industry is relying on technology to affect the costs of exploring for hydrocarbons in the following ways: - Reduce operating expenses (OPEX) by automating the processes used to explore and produce hydro - lncrease net present value (NPV) by providing systems that enhance the recovery of hydrocarbons f carbons, reducing the frequency of unplanned intervention, and improving information and knowledge management to decrease operating inefficiencies. From reservoirs. The new technologies improve production techniques to delay and/or reduce the production of water from downhole drilled and that will reduce the number of surface facilities required. The surface equipment requirements to handle increasingly larger quantities of hydrocarbons at these facilities should also decrease with the implementation of new technologies. - Reduce capital expenditures (CAPEX) by creating processes that will decrease the number of wells New processes for drilling, completion, production, artificial lift, and reservoir management have been created by advancements in technology in fields such as high temperature sensory, downhole navigation systems, composite materials, computer processing speed and power, software management, knowledge gathering and processing, communications and power management. Horizontal drilling and new fracture techniques have allowed operators to produce hydrocarbons profitably from areas that were uneconomical just a few years ago. Sensor technology in conjunction with data communications techniques provide on-demand access to the information necessary to optimize hydrocarbon production levels and achieve costs goals. Surface and downhole sensors are changing the way hydrocarbons are produced by optimizing production from downhole, supporting extend the life of artificial lift systems and providing information used to update reservoir and production models. A new technology that combines sensors with wireless telemetry provide the operators with new versatility and capability to place sensors in areas of the wellbore that were prohibitive due to technical difficulties and/or economic justification. The ability to communicate in and out of the wellbore using wireless systems can increase the reliability of the production system and decrease the amount of time required for the installation of the completion hardware in the wellbore. The elimination of cables, clamps, external pressure and temperature sensors, as well as splices on the cable that can fail inside the wellbore provides a significant advantage when attempting to place sensors in wellbores to monitor production or to optimize the pumps used in Artificial Lift applications.

WIRELESS SIMULTANEOUS ACQUISITION OF DYNAMOMETER AND FLUID LEVEL DATA FACILITATES ROD PUMPED WELL OPTIMIZATION

Real time analysis and visualization of the performance of a rod pumped well are achieved using multiple small and

compact wireless sensors that simultaneously transmit acquired data to a digital laptop manager that integrates the

measurements, displays performance graphs and provides advanced tools for analysis and troubleshooting of the

pumping system.

Battery powered wireless sensors for fluid level, pressure and dynamometer data acquisition are easily deployed and

quickly installed on the well. The laptop manager automatically recognizes and commissions the sensors. The user

sets up and controls the acquisition of data which may include multiple sensors that synchronously monitor variables

such as tubing and casing pressures, fluid level and polished rod acceleration/position and load as a function of time.

Elimination of cables and connectors improves the reliability of the hardware and data while speeding up the set-uptear-

down process. The user interface presents a smart instrument rather than a complex application.

Among the many innovations provided by these well performance analysis tools stand out the real time visualization

of the operation and fluid distribution in the down-hole pump, the simultaneous display of quantitative surface and

pump dynamometer graphs in conjunction with fluid level and wellbore pressures. Acquired data, wellbore

description and pumping system characteristics are saved as a historical data base creating a continuum of the well's

information and performance for direct comparison and detailed analysis.

The paper describes the hardware and user interface, the procedures for installation and acquisition and several

examples of field data and well performance analyses for a variety of rod pumping installations.

Wireline Retrievable Progressing Cavity Electric Submergible Pumping System Field Trial

Development of the REDA PC progressing cavity electric submersible pumping system began in 1991. The primary driving force behind this product development was the problem of accelerated wear of sucker rods and production tubing in deviated and horizontal wells when using surface driven progressing cavity pump systems. Many producers were replacing sucker rod and production tubing strings multiple times per year. This was severely affecting the economic viability of the oil wells. Since May 1994, REDA PC units have been installed in over 60 oilwells. The main cause of pulling the pumping system has been pump life. The harsh downhole conditions reduce the pump"s, ability to produce fluid while the REDA PC drive system is normally unaffected. As a result, a customer requested that a system be designed that would allow the pump to be pulled and replaced while leaving the bottom drive system undisturbed. This paper will describe the tubing deployed REDA PC system and explain the wireline retrievable configuration, the in-well testing to date, and the future developments for the system.

WOLFBERRY TRANSISTION IN STIMULATION

The "Wolfberry" play is named after the two main productive formations, the low-permeability Wolfcamp and Spraberry, and is a very large part of the everyday business in the Permian Basin. Activity in the Wolfberry has recently increased, spurred by the current relatively strong oil prices. However, the economic foundation of these producing wells is their stimulation and the management of completion costs. All of these wells require multistage fracture treatments to achieve economic production and therefore significant effort has been given to continuous improvement in efficiently completing and fracturing Wolfberry wells. To illustrate the evolution of the optimization process, a retrospective of the changes implemented in fracturing Wolfberry wells over the past 10 years in several counties in the Permian Basin is presented. This paper addresses in particular, choices involved in optimizing stimulation stages (including perforation schemes), treatment fluids and proppants, to maximize net present value contribution of the hydraulic fracturing treatments.

Working Pressure Upgrading of Wellhead Equipment For Stimulation Work

One of the most common problems encountered in designing a stimulation treatment is a low working pressure rating of surface equipment. Quite often, tubular goods are capable of much higher working pressures than the wellhead equipment, and the primary limit of pressure and injection rate is above ground. Breakdown and "Ball Out" treatments are often restricted by low working pressure ratings when the maximum allowable pressure at the pump is less than the pressure required to inject fluid into new or fluid-damaged perforations. Even though high pressures may be required for only a few minutes, it is vital to successful completion of a well that each perforation or zone be opened. Pressure limitations can be especially critical since the fracture area developed and proppant transport are direct functions of injection rate. When the pressure limiting component of a well system is above ground it can usually be "upgraded" safely and reliably by one of these methods: 1. Isolating the wellhead from treating pressure 2. Substitution of a "Treating Tree" for the production Christmas tree 3. Special landing joints or "Top Out Joints" for working through blow out preventers or wellhead assemblies where conventional trees have not been installed. Each of these methods has its strong and weak points and warrants detailed examination.

Working With Oil And Gas Rules And Regulations

Almost everyone connected with the oil and gas business will, at one time or another, be faced with rules and regulations governing oil and gas operations. The purpose of this paper is to present a generalized concept of some of the laws adopted by the various regulatory agencies in Texas and New Mexico. To completely encompass all rules and regulations in effect in the space and time allotted would be impossible. But, by supplementing the information contained in this paper with the reader's own knowledge and that available from other sources, one may gain a broader perspective of this particular phase of the oil and gas industry as well as a more complete understanding of the workings of the regulatory bodies.

Workover And Stimulation Of Water Injection Wells Using Continuous Coil Tubing

Continuous coil tubing has become a viable alternative to the conventional workover method of injection well cleanout. With the increase in the wellhead price of oil, a greater emphasis is placed on the efficiency of in-place waterfloods. When an injection well within a flood becomes plugged, the method by which the well is monitored should indicate if there is a problem. Based on that indication and all available relevant data, a decision can be made as to the kind of problem which has developed and likely methods of correcting that problem. The use of coil tubing in many cleanout procedures is a cost- and time saving method. The circulation method is accomplished without the need of moving or disconnecting any part of the injection string. The wells do not have to be backflowed and stimulation jobs can be done with minimum exposure of the injection string to the corrosive effects of acid. A treatment technique can be designed to correct or counteract problems within the injection profile on a point-to-point basis.
