New Technology to Enhance Applications of Borehole Image and Sidewall Coring

17 Juni 2015 - 17 Juni 2015
The quest for hydrocarbons has moved from easy to find and easy to produce reservoirs to more complex reservoirs in terms of their location and their producibility potential. It is no surprise that technology has kept pace with the increasingly complex demands from oil and gas industry to enable the operators to achieve their objectives in a cost effective and efficient manner. Today many technologies developed to aid formation evaluation studies for exploration and development of conventional hydrocarbon have found their use in unconventional energy business. Borehole image measurements and sidewall coring are considered as key input for formation evaluation programs. Borehole images with their high vertical and spatial resolution are capable of providing detailed information on texture, fracture and pore-distribution and thin-bed character of reservoirs. Such key details help the operators in various stages from acquisition to production and development. Sidewall coring is a cost effective way of acquiring formation samples for evaluating reservoirs through various lab-analyses and for calibrating logs. Both these measurements have evolved a great deal from the time they were introduced. Among various borehole image types available in industry the electrical conductivity based images are most commonly used. Due to basic measurement principle the quality of images depends a great deal on the type of fluid in the borehole along with the number of sensors in the tool. Until recently there was a big gap in our capabilities to acquire quality images in very high resistivity reservoirs drilled with high salinity mud and in the reservoirs drilled with oil based muds. That however is not the case anymore; recent advances in measurement technology have removed this gap. On the other hand sidewall coring technology has added a large volume mechanical rotary sidewall core. The core samples acquired using new technology allows the operators to acquire plug size cores with more flexibility in core-point selection beyond their key reservoirs. These two measurements provide a first-hand understanding of reservoirs in terms of their broad internal architecture and basic petrophysical character. Their applications and benefits are discussed in this presentation.
