Butler seeks to review not only the drilling but also the utilization of horizontal wells for the recovery of traditional crude oils and gas, along with the upturn of heavy oils and bitumen. The researcher finds out that horizontal wells appear to hold immense promise for a non-expensive production of oil. According to the investigator, horizontal wells can be used to mitigate coning issues. Additionally, the research claims that the cost of horizontal wells is not expansive when compared to other wells.
Butler is well aware of the role that his study plays in the field of oil engineering. Several aspects attest this particular claim. Foremost, the research motive or purpose is well clarified. It is described in a manner that every interested person will understand. Additionally, the researcher uses a precise methodology to facilitate his study. He defines each concept or variable, identifies the relationship between them, and analyzes data in a way that produces meaningful results.
High validity and reliability also characterize the study. Its validity comes in the sense that the researcher uses a series of examples. Additionally, Butler cites the findings of the previous studies and at the same time, he uses expert assertions to support his claims and arguments. The reliability is traceable given that the conclusions of the study have been replicated in the previous studies.
While this is the case, the study has some deficiencies. Of central importance is the notion that Butler seems to be somewhat technical. As such, there is a range of technical terminologies, which are pertinent to the engineering field. The use of technical terms, which are peculiar to a certain field, necessarily means that those who are not conversant with the terms are left out. Since they cannot understand the words, these people can easily be disoriented. There are those parties that are interested in the study by Butler. However, the technical words render them as outsiders.
