Coiled tubing drilling is an area where geologists and engineers must work together very closely, because an understanding of the formation is absolutely vital when planning wells drilled in tight gas sands, unconventionals, and in re-entries.  New developments in coiled tubing have made it possible to economically drill and produce often overlooked zones and re-entry drilling. Welcome to an interview with Richard Stevens, an expert in the area of coiled tubing drilling, who discusses the drilling technique and the importance of teams that include engineers and geologists.

New products can revitalize under-performing wells in mature fields. However, it is important to understand precisely why the well is not producing and to select the treatment that will work for the unique conditions of the well. Welcome to an interview with Olivia Carey, who has committed herself to finding new solutions for wells in need of revitalization. She discusses the products, candidate wells, and increased production using new products.

The goal of this two-day workshop is to proactively create opportunities yourself and your company in a low price environment. You will learn how to bring value propositions to operators. Revitalize reservoirs for less than the cost of plugging and abandoning, paid for by increased production. Rethink reservoirs and push paradigm shifts that will result in breakthroughs.  We will discuss how to use these times to pilot new products and technologies and thus position innovative companies to boom when conditions improve. This event is for engineers, geologists, geophysicists, land professionals, and entrepreneurs. *Please see our discounted rates for unemployed geoscientists, students and young professionals

Understanding fractures and fracture networks is absolutely vital for determining the best places to drill and for pinpointing sweet spots. Fracture characterization is also important for optimizing completion and production, both in vertical and horizontal wells. In mudrocks and shale plays, understanding fractures as well as the geomechanical properties is an important part of the well design. Welcome to an interview with Stephen Sturm, whose work with fractures and fractured reservoirs spans many of the world's shale plays.

Explorer Historical Highlights

When Occidental Petroleum Corporation was reorganized in 1959, its total oil production was some 100 barrels per day. By the time Moammar Gaddaffi nationalized the industry in 1969, Oxy Libya, the wholly owned subsidiary, was producing 800,000 barrels per day. Such an amount made Oxy Libya the eighth largest producer in the world.

VG Abstract

Production from unconventional petroleum reservoirs includes petroleum from shale, coal, tight-sand and oil-sand. These reservoirs contain enormous quantities of oil and natural gas but pose a technology challenge to both geoscientists and engineers to produce economically on a commercial scale. These reservoirs store large volumes and are widely distributed at different stratigraphic levels and basin types, offering long-term potential for energy supply. Most of these reservoirs are low permeability and porosity that need enhancement with hydraulic fracture stimulation to maximize fluid drainage. Production from these reservoirs is increasing with continued advancement in geological characterization techniques and technology for well drilling, logging, and completion with drainage enhancement. Currently, Australia, Argentina, Canada, Egypt, USA, and Venezuela are producing natural gas from low permeability reservoirs: tight-sand, shale, and coal (CBM). Canada, Russia, USA, and Venezuela are producing heavy oil from oilsand. USA is leading the development of techniques for exploring, and technology for exploiting unconventional gas resources, which can help to develop potential gas-bearing shales of Thailand. The main focus is on source-reservoir-seal shale petroleum plays. In these tight rocks petroleum resides in the micro-pores as well as adsorbed on and in the organics. Shale has very low matrix permeability (nano-darcies) and has highly layered formations with differences in vertical and horizontal properties, vertically non-homogeneous and horizontally anisotropic with complicate natural fractures. Understanding the rocks is critical in selecting fluid drainage enhancement mechanisms; rock properties such as where shale is clay or silica rich, clay types and maturation , kerogen type and maturation, permeability, porosity, and saturation. Most of these plays require horizontal development with large numbers of wells that require an understanding of formation structure, setting and reservoir character and its lateral extension. The quality of shale-gas resources depend on thickness of net pay (>100 m), adequate porosity (>2%), high reservoir pressure (ideally overpressure), high thermal maturity (>1.5% Ro), high organic richness (>2% TOC), low in clay (<50%), high in brittle minerals (quartz, carbonates, feldspars), and favourable in-situ stress. During the past decade, unconventional shale and tight-sand gas plays have become an important supply of natural gas in the US, and now in shale oil as well. As a consequence, interest to assess and explore these plays is rapidly spreading worldwide. The high production potential of shale petroleum resources has contributed to a comparably favourable outlook for increased future petroleum supplies globally. Application of 2D and 3D seismic for defining reservoirs and micro seismic for monitoring fracturing, measuring rock properties downhole (borehole imaging) and in laboratory (mineralogy, porosity, permeability), horizontal drilling (downhole GPS), and hydraulic fracture stimulation (cross-linked gel, slick-water, nitrogen or nitrogen foam) is key in improving production from these huge resources with low productivity factors.
