The two most basic tools used in petroleum exploration and production are well logs and seismic data. Their integration is essential to enhance the probability of success of exploratory and development ventures. In this module we concentrate on the subject of well logs. Although we always hope for success when we drill wells, we can learn valuable information from dry holes also. So, let’s see what we can ascertain from well logs.
We will go on a tour of some selected outcrops of the Cretaceous System of central Texas. This general area constitutes one of the best exposures of Cretaceous strata anywhere around the globe. In the course, we will emphasize various aspects of the development, stratigraphy, sedimentology, structure, and paleontology of these Cretaceous units. It is also our aim to provide you with additional historical and geographical data that will make this virtual field tour interesting and informative.
On February 22, the U.S. District Court for Northern California issued a preliminary injunction against suspension of the Bureau of Land Management’s (BLM) 2016 rule on Waste Prevention, Production Subject to Royalties, and Resource Conservation. The Obama-era rule seeks to reduce methane waste from venting, flaring, and leakage during oil and gas production on onshore federal and Indian lands. The latest court decision is one in a series driven by legal sparring between proponents and opponents of the measure, which began almost immediately after the rule was finalized.
The Senate Energy and Natural Resources Committee held a hearing on January 23 that underscored concerns surrounding the reliability and resiliency of the electrical power system, particularly under certain weather conditions. Experts on the witness panel discussed the overall performance of nation’s grid during recent cold weather events, and potential areas for improvement.
On January 19, the House Subcommittee on Energy and Mineral Resources held an oversight hearing to identify and examine regulatory obstacles to offshore geological and geophysical resource surveying on the U.S. Outer Continental Shelf (OCS). The hearing was held in response to a December 2017 Government Accountability Office (GAO) report detailing the permitting process for seismic research and identifies instances of inefficiency and inconsistency in meeting federal internal control standards. Congress is seeking compromises within the regulatory framework that would allow the U.S. to understand our offshore resource potential and ensure national energy security, while also minimizing the negative effects of anthropogenic noise in the marine environment.
On January 18, the House Natural Resources Subcommittee on Energy and Mineral Resources held an oversight hearing to assess the Department of the Interior’s (DOI) progress on eliminating burdens to domestic onshore energy production. During the hearing, witnesses commented on the regulatory uncertainties, inefficiencies, and inconsistencies that may disproportionately impact small businesses. BLM’s Deputy Director for Programs and Policy Brian Steed affirmed that recent actions to reduce regulatory burdens have created more revenue for the agency.
Secretary of the Interior Ryan Zinke announced his plans for the development of the National Outer Continental Shelf Oil and Gas Leasing Program (National OCS Program) for 2019-2024. The new Draft Proposed Program (DPP) aims to make more than 98 percent of the undiscovered, technically recoverable oil and gas resources in the OCS available for leasing and exploration. Less than a week after release of the DPP, Secretary Zinke informally announced that all of Florida’s coastline would be removed from consideration in the proposed five-year leasing program, prompting questions from various lawmakers and other stakeholders about the apparent preferential treatment given to the state.
The surge in recent years of earthquake activity associated with some oil and gas operations, most notably in Oklahoma, has spurred a range of actions and responses from state geoscientists and regulators. States have taken measures to monitor these earthquakes and moderate the activities that may be causing them, particularly the deep underground injection of large volumes of wastewater. Many states with extensive oil and gas operations but little or no increased earthquake activity have also adopted practices to prevent and prepare for potential induced earthquakes in their area.
