Characterization and Evaluation of Deltaic Sandstone Reservoirs of the Dunvegan Formation, Kaybob South Arman Ghanbari, Steven M
Characterization and Evaluation of Deltaic Sandstone Reservoirs of the Dunvegan Formation, Kaybob South Arman Ghanbari, Steven M. Werner, Lukas Sadownyk, Matthew Gonzalez, and Per Kent Pedersen Department of Geoscience, University of Calgary, Canada Summary Sandstones of the Cretaceous Dunvegan Formation within and around the Kaybob South Field are part of a legacy gas pool producing from a complex delta lobe. It is important to note that recently, oil production has also picked up in this area mainly with the implementation of horizontal wells. This presentation will investigate the complexities and variations of the Dunvegan from a geological perspective. Further, investigation will be undertaken on recent developments on a potential light oil play using horizontal drilling in the fine-grained deltaic sandstones of the Dunvegan. Introduction The Dunvegan Formation is a prolific gas producing unit in west-central Alberta. It was discovered in the 1950’s and has recently received attention for its oil production in horizontal wells within and near the Kaybob South (Figure 1). The area of focus in this study is the southwest of the Kaybob South region (Figure 1). This region also exhibits oil production on the peripheries of the pool where horizontal wells are located. The Dunvegan is stratigraphically trapped with deltaic sands acting as reservoir. The Dunvegan delta Figure 1. Adapted from Bhattacharya., 1994 – Kaybob gas pool is itself contains highly river marked by the yellow dot. The pool of study is within the red box where dominated deltas and a map of cumulative production is shown. Red production bubbles transgressive sheet sands indicate this is a gas dominated pool. -

Stable isotope and compositional analyses suggest that wet gases in the central study am are produced via active thermogenic gas generation, with gases sourced in the Doig and Montney formations. -
Kaybob Dunvegan Oil: a Not-So Unconventional Oil Play
Kaybob Dunvegan Oil: A Not-So Unconventional Oil Play Alison E. Essery, Jim C Campbell, Tangle Creek Energy. Suzan Moore, Moore Rocks. Teresa Marin, Petrography Consulting. Industry has become focused on “tight” or “unconventional oil resources”. Significant recent activity includes horizontal oil completions in conventional tighter marine sandstones such as the Cardium, Viking and Montney formations. These reservoirs comprise mappable sandstone targets, albeit with lesser permeability than discoveries made twenty years ago. The Kaybob Cretaceous Dunvegan oil play has very similar reservoir characteristics and more than 95 Dunvegan horizontals have been drilled in the last three years resulting in significant light oil production. The Dunvegan formation was exploited as a gas- and oil-bearing fluvial/deltaic play for several decades. The first horizontals were drilled in thick fluvial channels in the mid-1990s in the Latornell/Ante Creek/Simonette areas of Alberta. Recent oil production is occurring in more marine settings. The formation has been extensively studied and documented by many authors (e.g. Bhattacharya et al 1991, Plint 2000). Several clinoforming units or shingles (G-E) are interpreted to prograde to the east into coastal areas. In particular, the delta associated with the Dunvegan E unit at Kaybob incised far into the marine environment, so that it was subjected to the reworking process of waves and tides. Core and cuttings work contributed greatly to confidence of the interpretation of wave and tide reworked shorefaces. Detailed core work revealed good examples of shorefaces overlying slumped delta front sandstones as well as tidal bundles associated with the tidal currents. Core to log calibration showed that gamma log signatures can be unreliable for facies identification. -

Potential for Freshwater
POTENTIAL FOR FRESHWATER BEDROCK AQUIFERS IN NORTHEAST BRITISH COLUMBIA: REGIONAL DISTRIBUTION AND LITHOLOGY OF SURFACE AND SHALLOW SUBSURFACE BEDROCK UNITS (NTS 093I, O, P; 094A, B, G, H, I, J, N, O, P) Janet Riddell1 ABSTRACT Freshwater bedrock aquifers are hosted almost entirely by Cretaceous strata in northeast British Columbia. The most important prospective regional bedrock units for freshwater aquifers are the coarse clastic Cenomanian Dunvegan and Campanian Wapiti formations. Much of the Lower Cretaceous Fort St. John Group and the Upper Cretaceous Kotaneelee, Puskwaskau and Kaskapau formations are dominated by shale strata and generally behave as regional aquitards, but locally contain members that may host aquifers, including fractured shale sequences and coarse clastic intervals. In the Peace River valley, some of these aquifers are well known, but outside that region, hydrogeological data are sparse and many aquifers remain to be formally identified and delineated. Hydrocarbon exploration activity is occurring in new areas because of shale gas development. New exploration will generate lithological and geochemical data from areas where data is currently sparse, and will significantly improve our knowledge about the hydrostratigraphy of Cretaceous clastic units across northeast British Columbia.

Department The University of British Columbia Vancouver, Canada DE-6 (2/88) ABSTRACT Middle Triassic Doig reservoirs in the Fireweed, Buick Creek, Cache Creek and West Stoddart fields (94-A-13 to Twp.86, Rge.18) of northeastern British Columbia consist of deltaic and shoreline sands encased in shelf and offshore mudstones and siltstones. The reservoirs comprise a series of northwest and northeast trending elongate sand bodies that lie along a south-southeast depositional trend analogous to the position of the original Doig shoreline. Sediments of the Doig Formation are divisible into two facies associations and ten lithofacies representing deposition in shelf to offshore, and deltaic and inter-deltaic environments.
