We’re Always Looking for Newer & Safer Technologies
Weatherby Energy is active throughout North America, drilling both vertical and horizontal wellbores, capitalizing on new trends and technology in the industry. Our energy and expertise allow us to move forward with leading edge technologies that build on our tradition of success. The Company remains nimble and is poised to capitalize on opportunities throughout the oil patch.
Hydraulic fracturing is the propagation of fractures in a rock layer by a pressurized fluid. Some hydraulic fractures form naturally — certain veins or dikes are examples — and can create conduits along which gas and petroleum from source rocks may migrate to reservoir rocks. Induced hydraulic fracturing or hydrofracturing, commonly known as fracing, fraccing, or fracking, is a technique used to release petroleum, natural gas (including shale gas, tight gas, and coal seam gas), or other substances for extraction.
Coiled tubing refers to metal piping, normally 1″ to 3.25″ in diameter, used for interventions in oil and gas wells. The main benefits over wireline are the ability to pump chemicals through the coil and the ability to push it into the hole rather than relying on gravity. The tool string at the bottom of the coil is often called the bottom hole assembly (BHA).
It can range from something as simple as a jetting nozzle, for jobs involving pumping chemicals or cement through the coil, to a larger string of logging tools, depending on the operations. Coil tubing has also been used as a cheaper version of work-over operations. It is used to perform open-hole drilling and milling operations. It can also be used to fracture the reservoir, a process where fluid is pressurized to thousands of psi on a specific point in a well to break the rock apart and allow the flow of product. Coil tubing can perform almost any operation for oil well operations if used correctly.
The Slim-hole (Aka: micro hole or small hole) drilling technology is one of the most cost effective method of oil and gas reserve development. It involves drilling smaller diameter holes and using small diameter production casing and tubing. The use of small diameter well bore reduces the overall cost of exploration drilling and reserve development. The Oil Jet Pump is the industry smallest and able to be conveyed inside 2-3/8 or 2-7/8 inch production strings, thereby allowing slim-hole-micro-hole operators to retain economical operation factors associated with slim-hole development methods.
Ever-improving seismic images are a continuous goal across our industry. Seismic images are critical throughout our entire operations, ranging from New Venture, Exploration, Appraisal and Development endeavors. Imaging success in our offshore environments has yielded improvements in our emerging resource play activities. We have internal capabilities to acquire, process, and interpret almost any seismic program. We focus internal efforts on a select few programs which are proprietary in nature and outsource remaining efforts to established vendors.
Horizontal oil and gas well drilling has become one of the most valuable technologies ever introduced in the business. It is an enhanced oil recovery (EOR) or gas recovery method that is becoming more and more popular as the price per barrel of oil gets higher. Unlike a directional well that is drilled to position a reservoir entry point, a horizontal well is commonly defined as any well in which the lower part of the well bore parallels the oil zone.
The angle of inclination used to drill the well does not have to reach 90° for the well to be considered a horizontal well. Applications for horizontal wells include the exploitation of thin oil-rim reservoirs, avoidance of drawdown-related problems such as water/gas coning, and extension of wells by means of multiple drain holes.
Cost experts have agreed that horizontal wells have become a preferred method of recovering oil and gas from reservoirs in which these fluids occupy strata that are horizontal, or nearly so, because they offer greater contact area with the productive layer than vertical wells. While the cost factor for a horizontal well may be as much as two or three times that of a vertical well, the production factor can be enhanced as much as 15 or 20 times, making it very attractive.
To give an idea of the effectiveness of horizontal drilling, the U.S. Department of Energy indicates that using horizontal drilling can lead to an increase in reserves in place by 2% of the original oil in place. The production ratio for horizontal wells versus vertical wells is 3.2 to 1, while the cost ratio of horizontal versus vertical wells is only 2 to 1.
