September 2008 – Horizontal Cementing

Horizontal wells have become the most economic well configuration for many plays today. In order to effectively treat and produce horizontal sections, zonal isolation is required through cementing. To achieve this zonal isolation, several steps must be followed in preparing the well for cementing. They are: determining if cementing is necessary, selecting slurry design, and borehole preparation. Some innovations in cement have come in the form of expansive cement, foam cement, and acid soluble cement. These slurries perform specific functions and are reservoir specific. Improvements in borehole preparation over time have come in the form of evolving best practices and spacer and pre-flush chemistry. A successful cement job takes proper planning an preparation and this presentation will outline the guidelines.

November 2008 – Appropriate Hydraulic Fracturing Technologies for Mature Oil & Gas Formations

PRESENTATION

Hydraulic fracturing has been described as one of the three most significant technologies to be developed in the upstream oil and gas industry in the last 50 years (the other two being 3D seismic and horizontal wells). However, the traditional approach to hydraulic fracturing has been that it is a technology best applied to new wells, drilled into low permeability formations. It is true that fracturing has been highly successful in this environment - but it is also true that fracturing can be both technically and economically successful in a very wide range of reservoirs, including depleted oil and gas assets. Various strategies such as skin bypass fracturing, batch fracturing, screenless frac-packs, coiled tubing fracturing and neutral density proppant fracturing can be combined with complimentary techniques for zonal isolation, relative permeability modification and scale inhibition, to produce low-cost, high-value solutions for mature assets. Success in this environment is not necessarily about using the latest and greatest fluid system or computer monitoring technique. The successful application of hydraulic fracturing to mature oil and gas reservoirs is about recognizing that there is a wide range of appropriate solutions available. A number of case histories will be used to illustrate the effectiveness of these techniques, when they are systematically applied.

One idea I would like members to take away from this lecture: hydraulic fracturing is not just for new wells in tight formations.

December 2008 – Perforating with Lasers

Lasers are on track to provide safe, non-explosive, damage-free perforations.

For decades, experts have considered the potential of laser energy to penetrate rock as an alternative well construction and completion method; however, the technical application of lasers was dismissed as energy intensive and inefficient. Conclusions from 40 years ago continue to influence industry misperceptions despite massive developments in laser systems and applications.

New breakthroughs in laser technology have addressed efficiency, portability and reliability issues required for successful commercial field applications. The latest multimode configuration of fiber lasers are now capable of delivering multiple kilowatts of power from an efficient, compact laser source with excellent beam quality, reliability and long life. They represent an enabling technology that opens the door for near-term subsurface laser applications at remote sites. Examples of remote surface field applications have been made.

The application of high power lasers to create the path between wellbore and target reservoir could significantly reduce the primary drawbacks of using explosives - safety and damage. It is desired that the process of cutting through steel, cement and rock by the laser would leave a relatively damage-free area at the interface of the reservoir and allow a connection free to flow with minimal skin damage. Recent research results have proven the laser perforation concept under multiple downhole conditions, including pressure. Other completion applications are envisioned, as well.

January 2009 – Powerwave Injection Technology – Secondary Recovery, Waterfloods, and CO2 Floods

In the oil industry, any progress in technologies designed to enhance production is most commonly based on empirical discoveries and only later followed by attempts to develop a consistent physical theory to explain, analyze, and predict field behavior. However, in 1997, a group of scientists and engineers sought to change that mindset. Through a series of laboratory tests utilizing a rigorous theory, this group developed a new fluid flow enhancement technology known as the PowerwaveTM process. Powerwave is an injection technology wherein a volume of liquid is introduced through casing or tubing and is pulsed at high accelerations by downhole devices into the reservoir. The injected fluid then increases the porosity, pressure, permeability, saturation, and homogenization of an ever-increasing coherent volume of the porous media through porosity dilation (expansion of the pore throat).

Powerwave is modeled after the effects of earthquakes on the pores in rocks to stimulate the flow of oil. The technology allows oil producers to tap into mature oil fields, in addition to wells that are not producing as well as they should. As early as the 1950s, earthquakes were observed to affect fluid levels in oil wells, and production increases were often reported. Beneficial effects decreased over time following a seismic event. This led to the concept of seismic excitation for flow enhancement.

To increase oil recovery, many field attempts in the United States, Russia and China (among others) have been made to induce and couple seismic waves as a method for secondary oil recovery during traditional oilfield waterflooding. In theory, vibratory forces are thought to promote the movement of oil by diminishing capillary forces thereby reducing adhesion between the rock and fluids. This causes trapped oil to be liberated and flow with the CO2 or waterflood.

Implementation of Powerwave in injection wells has led to injectivity index increases of 40 - 900%.

February 2009:  The EOR Kiss of Death – It was a Technical Suicide

Abstract

The One Idea: How business risks of a CO2 enhanced oil recovery project are handled can make or break a project. The first questions that must be answered in a CO2 EOR project are always technical:

  • Can CO2 recover incremental oil?
  • If yes, at what rate and volume?
  • What is the necessary investment?
  • What are the ongoing operating costs?

The answers to these questions will determine whether the project will be a technical success, but then you have to delve into the business aspects of the project. Using real examples and experience from the creation of the Weyburn CO2 Miscible Flood, the business risks for a typical potential project will be highlighted.

The answers for your project will be different than for Weyburn but the questions you have to ask are the same: Will my supplier be around long enough to give me the CO2 I need or will he be bankrupt next year? Should I build the supply pipeline or spread the risk (and the reward) with a third party builder? Can my partners really afford this project? What can I do if I need their vote to get the project approved, etc.?

Understanding these business risks and the measures you must take to quantify and minimize them will go a long way to ensuring your project is both a technical and an economic success.

May 2009 – How Logs can Help You Make Better Shale Wells

Do you know your clay type and percentage? Are there structural or lithology changes? Do you know your borehole stresses and anisotropy? Do you have a good cement job? How will you divide your well for perforations and hydraulic treatment staging? Do you know where your production is coming from?

This presentation addresses which of these questions can be answered by logs at each stage of the life of your horizontal borehole: while drilling, in open hole after reaching total depth, in casing before, during or after hydraulic treatments.
