Moving their directional drillers into their Houston real-time remote operations centers has improved drilling efficiency for two of the top shale producers. This paper presents an interdisciplinary approach to the description of tectonic dislocations made on the basis of interpretation of seismic data, petrophysical analysis of well-logging data in horizontal wells, and inversion of a multifrequency propagation tool. This work presents a systematic geosteering work flow that automatically integrates a priori information and real-time measurements to update geomodels with uncertainties and uses the latest model predictions in a decision-support system (DSS). The use of intelligent software is on the rise in the industry and it is changing how engineers approach problems. A series of articles explores the potential benefits and limitations of this emerging area of data science.

The formation of scale deposits upon tubing, casing, perforations, and even on the formation face itself, can severely constrict fluid flow and reduce the production rate of oil and gas wells. In addition to lost production, a considerable portion of the workover budget is expended in efforts to remove these deposits and prevent their recurrence. As a consequence, scale prevention has been and continues to be a common exercise and is successfully applied in many areas. Although the principles behind scale formation and prevention are generally well understood, there are many new forms of scale prevention and new scale inhibitor application technologies. Some people consider scale prevention a mature subject matter area with "nothing new under the sun," but in fact there are many new developments, some of which will be highlighted in this presentation. This presentation will review the major elements that normally comprise any effort aimed at the successful control of scale deposition, starting with scale identification, followed by scale prediction, inhibition, and removal. Several case histories will illustrate the application of these scale control techniques in oil production facilities. Scale formation can be a show stopper, but if properly managed, scale can be prevented economically. Charles Hinrichsen earned a BS degree in Chemistry from the State University of New York at Stony Brook and an MS and PhD in Chemistry from Cornell University. He worked at Texaco and later Chevron for forty years at Chevron's Energy Technology Company as a Chemical Treating Specialist. From 1998–2001 he coordinated Texaco's chemical operations in Angola, West Africa, and from 2001–2003 he served as Senior Corrosion and Chemical Treating Engineer in Wafra, Kuwait.
This paper discusses a study undertaken to gain better understanding of nuclear magnetic resonance (NMR) characteristics of volcanic reservoirs with different lithologies. This paper compares the results of gas identification and lithology identification using pulsed-neutron spectroscopy in openhole and casedhole environments. Coring is essential to offshore exploration programs—but sometimes cores are taken from the wrong formation or return to surface in poor condition. One firm thinks it can solve these costly issues with a first-of-a-kind coring device that uses logging instruments that add accuracy and integrity. The rising cost of fracturing offers a significant incentive for finding ways to avoid unproductive rock.
This paper presents a data set involving the pumping of multiple, unique chemical tracers into a single Wolfcamp B fracture stage. This paper introduces a new core-analysis work flow for determining resistivity index (RI), formation factor (FF), and other petrophysical properties directly from an as-received (AR) set of core samples. Houston-based Surge Energy drilled the Medusa Unit C 28-09 3AH well in the Midland Basin to a TMD of 24,592 ft, with a total horizontal displacement of 17,935 ft, or 3.4 miles. This paper discusses a project with the objective of leveraging prestack and poststack seismic data in order to reconstruct 3D images of thin, discontinuous, oil-filled packstone pay facies of the Upper and Lower Wolfcamp formation. A new technique that analyzes scanning electron microscope (SEM) images of formation samples has been used to measure porosity and total organic carbon (TOC) in the Wolfcamp Shale of the Delaware Basin in west Texas.
This paper presents the results of a 3-year project aimed at mass field implementation of ultrahigh-speed (UHS) electric submersible pump (ESP) systems in western Siberia. This paper presents an interdisciplinary approach to the description of tectonic dislocations made on the basis of interpretation of seismic data, petrophysical analysis of well-logging data in horizontal wells, and inversion of a multifrequency propagation tool. Russia’s need to continue expanding the oil and gas business is pushing it to look east for more production and markets. But everywhere it turns there is stiff competition in a world awash in oil and gas. Russia has looked to the east to find more oil and gas, growing markets and investor support, allowing it to shrug off the global slump and trade sanctions.

The Permian Basin is now influencing the upstream water market on the way down, while many questions swirl around the implications of unprecedented shut-ins. The industry has very limited experience in shuttering production on a large scale in unconventional reservoirs. Many questions remain on how stimulated, nanodarcy shale reservoirs may respond. George King discusses the paradigm shifts needed in the industry. The merged companies will offer large-diameter coiled-tubing, directional drilling, snubbing, wireline services, and pressure pumping services.
This short course is designed to provide knowledge and understanding of surface equipment, downhole tools, various applications, and operational contingencies for rigless well interventions involving coiled tubing, slickline, or wireline. The participants will learn first-hand knowledge of the capability of each intervention and what to consider when choosing which intervention method to utilize. The course will cover recommended risk mitigation and well control barriers as well as best practices gained from years of experience and application. To further illustrate the intervention methods utilized to resolve well issues or enhance well performance, real world examples for coiled tubing, slickline and wireline will be presented and discussed. Recognize and explain function of CT, Slickline, and wireline equipment Recognize and explain function of the Pressure Control Equipment and Bottom-hole assembly's for coiled tubing, slickline and wireline interventions.
