Oklahoma Oil Expansion: Utilizing Unconventional Technology to Develop Conventional Targets

Oklahoma’s Anadarko Basin, one of the world’s super basins, is currently known for horizontal drilling in the Woodford Shale, the principal source rock in the basin. However, above the Woodford, many attractive oil and gas reservoirs have been pursued with vertical technology over the past 100 years. As one of the deepest basins in the United States, with horizontal Woodford wells routinely drilled between 14,000 to 17,000 FT TVD, there is a lot of rock above the source in which hydrocarbons have accumulated.

Lynx Oklahoma Operating is focused on developing targets for horizontal drilling within and adjacent to existing legacy fields in the Anadarko Basin, specifically Caddo County, Oklahoma. After analyzing multiple targets in Caddo County, including the deep Woodford, Meramec, Springer, Red Fork and multiple Hoxbar reservoirs, Lynx decided to initiate its horizontal program targeting crude oil in the Hoxbar Marchand. The Hoxbar Marchand is a sandstone oil reservoir with a typical gravity of 42 to 48 degrees API at 9,500 FT to 10,500 FT TVD, historically developed utilizing conventional vertical technology since the mid-1960s.

Legacy vertical Hoxbar Marchand wells vary in performance. Many are marginal vertical producers and vertical wells drilled but never completed for various reasons, including reservoir properties deemed commercially unproductive, commodity prices and operator challenges. Lynx’s Chief Executive Officer Nelson Bolen states, “These variables provide an attractive dynamic when analyzing conventional reservoirs for modern horizontal unconventional development, as the vertical penetrations provide a detailed subsurface database, showcase producibility, but leave most of the oil behind.” Although vertical Hoxbar Marchand development was in thicker, clean sandstones and thinner, dirtier sandstones, prospects in the thinner, dirtier rock were often not developed beyond the first few wells. This provides an opportunity to add value utilizing modern unconventional technology on legacy conventional rock.

According to Al Warner, senior vice president of geology, “Lynx’s geological approach was to first construct a series of detailed cross sections wherein individual sandstone benches, generally 5’ to 25’ but, in some instances, up to 50’ were correlated. These individual benches were then mapped over their entire extent, providing targets that, in many cases, extend beyond the known limits of a given field or play. In a number of instances, this detailed ‘splitting’ of the sandstones included mapping and extending the shalier sandstones over broader areas which have proven commercially productive.”

When targeting sandstones, like the Hoxbar Marchand, the gamma ray log is not the gospel when identifying productive or nonproductive rock. Other factors must be considered during drilling to stay in the optimum interval. Hydrocarbon shows both gas and oil provide excellent evidence of potentially productive rock, but are not always easily identified, especially when drilling with weighted oil-based mud. Rate of penetration is another excellent leading indicator that is utilized during geosteering and for target changes.

Crucial Takeaways | The Expansion of Early Stage Technological innovation Enterprise Financial commitment and Enhancement in Electrical power and Oil and Fuel | McDermott Will & Emery

How is engineering impacting the strength industry? In the most up-to-date webinar in the Power Transition sequence, McDermott Will & Emery Spouse Parker A. Lee hosted Shawn Helms, co-head of McDermott’s Technological know-how and Outsourcing Exercise Team, Nadine Herrwerth, managing director at TWTG, and BJ Walker, managing director at Tudor, Pickering, Holt & Co for a 30-minute discussion where by they opined on the current and potential effect technologies plays on regular and renewable vitality corporations.

Underneath are crucial takeaways from the webinar:

1. Industrial World wide web of Things (I-IOT). I-IOT products and solutions and expert services can be used to make improvements to internet site safety and efficiency. I-IOT merchandise have the capacity to observe products, such as valves and temperature sensors on equipment, and file information on exterior dashboards for analysis and alerting. As a result of the use of knowledge assessment, information gathered by I-IOT products can discover developments, create versions and detect long run gear failure. As a result, I-IOT products and solutions and companies can improve the efficiency, dependability and safety of machines.

Although the software of I-IOT gadgets is reasonably new to the sector, these products are able of getting retrofitted to recognized and previously operational websites.

2. Know-how Businesses and Electricity. When technological innovation providers are significant individuals of vitality output, they can also give considerable insights and intelligence in regard to electrical power use and output. Synergies between technology and electrical power industries are repeatedly evolving and providing enhancements in energy investments, efficiencies and trustworthiness. For illustration, drones are capable of leveraging artificial intelligence to maximize effectiveness and regularity of gear checking and inspections, significantly gear that is positioned in distant regions (these as offshore).

3. Trader Concentrate on the Strength House. An crucial topic in the oil and gasoline marketplace is the new concentrate on transforming the field to a generator of cashflow. In attracting new buyers to the power market, significantly as new systems are introduced, buyers should really know there is usually a for a longer period wait period to receive a return on financial commitment than what a common investor would typically be expecting. In addition to normal buyers, engineering companies are investing in renewable strength sources for purposes of environmental obligation and in order to electrical power their personal business. It is envisioned that this development will keep on to improve in strength intensive areas, this sort of as the cryptocurrency house.

4. Engineering in Traditional Oil and Gasoline. Even though not broadly appreciated, the oil and gas industry has normally been closely reliant on know-how and an area exactly where innovative technologies are developed—and that is undoubtedly the situation right now. Due to the fact oil and fuel experts are proficient with, and conversant in, the software of new systems, look to those professionals to be market leaders in the power transition as new businesses and products and solutions are formulated.
